From a software/hardware engineering perspective, how difficult is it to get into the slot machine game? I imagine it must have quite a rigorous set of guidelines and testing procedures that must be followed diligently to avoid running afoul of regulations set out by gambling states.

Also, I assume it must require a lot of trade show visits to try and sell major casinos on your machine, since the number of customers for your machines is severely limited. Is it an upfront cost business (aka, they pay you $XXX for each machine) or is it more of a partnership with the makers where the casinos share profits on the machines with the developer/designers? Off the top of my head, I'd think the latter would be more feasible as I'm sure popularity of machines must be somewhat short lived, as there always seems to be different machines all the time.

Anyway, I'm curious if anyone with more experience in this area could give some brief highlights on what it's like working in that arena. I've always been curious :)

I worked in the business for a number of years and still have friends/colleagues that are there.

From an engineering perspective slot machine design isn't very hard at all. It's pretty much video game design. There's a relatively recent CPU putting down images, playing back video, doing some light/sound choreography, and maybe doing some mechanical motion on some games. Let's put it as slightly more complex than Candy Crush but way less complex than writing Halo. There's also a mechanical component with artists and designers making cabinets, art glass, and wacky add-ons that sit on top or around the machine.

The hard work in slot machine design is in the math of the slot machine. You're trying to design a game that balances something interesting on-screen with enough volatility that keeps players hooked. If you decimate their bank in the first 100 spins that player will never come back. One typical way to manipulate this is through the secondary games or bonus games that pop up on certain reel combinations. At first this was a way to work around certain patents (the most famous being IGT's Telnaes patent) and now players just come to expect various levels of extra action when certain slot reels are hit. Every player likes something different, of course. IGT's Double Diamonds reel-spinning slot is over 25 years old and players still look for it.

The math also has to jive with the gaming board. Certain states will mandate minimum payout percentages, or a mixture of these that average a certain payout. (This is why dollar slots in Vegas pay way better than penny slots. As long as all the action in the casino averages to the legal minimum, they're okay). Your typical slot manufacturer has a number of math/stat MS or PhDs working out the numbers on paper as well as a testing department that tries to verify the math empirically. I'll say "tries" because some designs are so complex and non-deterministic or dependent on player choice that it can't be verified entirely on paper anymore. Almost all American jurisdictions employ independent gaming labs that inspect the code and verify the math as well before the slot is approved to release in a given state. If you can get approved in Nevada, you're usually good everywhere as a rule of thumb.

And then yes, the theme of the slot has also become incredibly important. Licensing pop culture items (movies, TV shows, dead musicians, celebrities, etc etc etc) is a constant fight between the manufacturers to capture and leverage into a usable slot idea. Some think it is creatively lazy to grab the next hot movie and turn it into a slot. Some think that's what you need to do to attract people's attention in a visually crammed environment. C'est la vie.

A slot machine designer worth his salt can mix and meld all of these things into an interesting game. New and different game mechanics are hard to come by, though. When something does hit, you'll see that model replicated dozens of times with slightly different math or new themes slapped on top of it. You throw a lot of shit at the wall to see what sticks.

Business wise, up until a few decades ago, slots were sold by manufacturers and entirely owned by the casinos. In the last 20 years or so this has transitioned into a participation relationship where the manufacturers own, maintain, and operate the games themselves and share a percentage of the handle with the casino. This has made the business a lot more cutthroat because a streak of lousy games can get you kicked off a property (or corporation) entirely. This is the downside of throwing shit at the wall, so you test and test continuously at smaller properties. Participation also allows interesting game mechanics like multi-casino slots (like Megabucks) where the manufacturer is holding the jackpot in an interest-bearing account in their reserves. Think about that when the jackpot is in 9 figures and nobody has hit it for a year.

Anyway, if you're really interested, the big companies are always hiring. These days it's IGT in Reno, NV and WMS in Chicago, IL. There are smaller companies here and there (Konami, Aristocrat, Mikohn) and then a constellation of independent design groups that consult and design games on spec for the big dogs. Most designers work their way up from programming games or designing art for slots but if you have any video game or casual game experience there's always room for new talent.

jedberg2• 12 years ago

IGT's Double Diamonds reel-spinning slot is over 25 years old and players still look for it.

It's the only slot I'll play because it has the best pay table in the casino. It's the only one that pays 1600 coins for a 2 coin bet with sufficient payouts otherwise.

FreeKill2• 12 years ago

Thanks for the detailed reply. Very informative. Much appreciated... I had no idea those big progressive jackpots were actually managed by the slot machine makers and not the casinos themselves. It does make sense though, when you think about it, because how else would it work cross casino?

Stumbled across this interesting article: http://www.wired.com/2011/07/ff_scammingslots/

The big issue isn't engineering, it's licensing. In the words of the attorney that helped me with a Nevada gaming license application, "They really want to make sure you're clean before they give you a license to steal". For example, if you went to high school in Hawaii, they will send two gaming agents to Hawaii - on your dime - to interview your high school teachers. The process is long and expensive.

And that's just Nevada. You have to be licensed in each individual jurisdiction where your games will be shipped. This, of course, is all before you even broach the subject of putting your game on casino floors with slot/table game managers.

As far as revenue models, both of those you mentioned are used. This also goes back to licensing - if you are only licensed as a manufacturer (a slightly less onerous process) then you cannot get a percentage of profits. You must have an operating license to obtain a percentage. This is why many table game manufacturers (3 Card Poker etc) get a flat fee per table per day instead of a percentage. The machine market is dominated by IGT and WMS, and good luck penetrating it. You may, however, be able to develop a fun game and license it to one of the big slot firms. Probably the easiest way.

joezydeco7• 12 years ago

If you hang out at the back of the Global Gaming Expo (aka G2E), there are dozens of inventors in little booths trying to show off their new game and get you to try it. If you don't have a connection to a big company, this is one way to get discovered, but by judging what I've seen in some of those booths, you really have to have a compelling, easy, addicting game to get noticed. And most of those little guys have none of the above.

pardon the hijacking, but what's with this trend of everything above the fold looking like an entire complete page with almost no content? half the time i land on sites like this, i sit there for 5 seconds wondering where the hell the content is. the scrollbar is not that visible, guys. if i dont see partial content hiding at the bottom of the fold which would clue me into the fact that there's 10 more pages worth of scrolling, i'm not gonna "get it" by noticing a scroll bar.

the pretty UI is not worth the horrid UX

EDIT: i think repliers are focusing too much on scrollbar visibility. this isnt the main issue. i have no problem with the scrollbar being visible on other sites. it's plenty visible on my Win 8.1 / Firefox 1080p res. The problem is that A) i dont want to scroll an entire page before i begin reading and B) i dont want it to be the primary (and sole) indicator of additional content. I have to look over to the side to get the only cue, it's really annoying.

/rant.

dm25• 12 years ago

I've noticed that too and also do not like it.

I'd prefer the traditional style article and thumbnails where necessary (not just for the sake of cramming images into articles).

Maybe they've done testing and this style article gets read/shared more, it certainly looks more official and permanent but it's still just a blog post / news article.

This is where I first saw it, and it's annoying to read the huge text and adjust to the images that float under text: https://medium.com/war-is-boring/that-time-an-air-force-f-16... Apparently they never even considered what it would look like when someone tries to print that article, the 1st half of the page is a solid black image, then the text is laughably large.

NotAtWork2• 12 years ago

That page you linked is horrendous!

sosuke• 12 years ago

I don't love it, but think of it as a book or magazine cover or full page picture at the start of an article. I've just started scrolling on every page I land on at this point.

LeoPanthera• 12 years ago

the scrollbar is not that visible

That's the real problem. It's become very trendy to have nearly-invisible, or even actually-invisible scrollbars. This is a horrible loss of UI and I have never understood it.

leeoniya3• 12 years ago

the thing is, it's as visible as it always was. i'm on Win 8.1, Firefox - it's plenty visible, it's just not the first place i look and shouldn't be.

JohnTHaller• 12 years ago

Not being able to see your scrollbar is the fault of your browser's and/or OS's horrid UX.

megablast• 12 years ago

Is it hard to scroll on your machine. On a mac it is incredibly easy to scroll on a webpage, that is why I think these designs might be more popular.

leeoniya3• 12 years ago

nope, very easy. scroll through thousands of lines of code per day. what i dont scroll through every day is a lot of content-less whitespace - i'd complain about that too :)

AgentME• 12 years ago

What's really annoying is the pages where the background image stays fixed as you scroll down (and text starts to scroll up over the background image). Sometimes I believe I'm at the bottom of the page when scrolling appeared to do nothing and I get ready to close the tab before I notice some text had come into view.

Er, I usually notice the text. When I first started seeing some of these, I remember thinking some of them had failed to load when I couldn't scroll, so I guess I don't always notice the text.

I come from a country where casinos are much rarer than they are in the US, and I recently went in my first casino ever after living in the US for 4+ years.

So I entered this weird place in Montana, with colorful machines everywhere. A more experienced friend instructed me to play a certain machine, in which I put $5 and got 100 virtual "tokens" in exchange. Then the machine asked me to pick 7 random numbers from a 10x10 grid. I touched the 7 numbers, and pressed a flashy "Go" button. The machine "randomly" (of course I have no certainty that it was truly a random process) picked 7 numbers, and only 1 of mine matched. Total gains: 0. I repeated the process several dozen times: select your numbers, press a button, watch the machine make funky sounds as it "randomly" selects number, see if yours match. The best round I got was when 3 of mine matched, and I got back something like 10 credits, going from 47 to 57. 10 minutes later, I was at 0.

It strikes me as a tragedy of our modern society that such contraptions make for a significant portion of state income, and that they are as popular as they are. It is sad that the average American citizen does not have a sufficient grasp of basic probabilities to even consider putting money in such a machine, because it means that the school system essentially fails at preparing kids for the real world. And it is sad that governments are encouraging those temples for theft to prosper the way they do. Because it really is theft - just a kind of theft where the victim is coaxed into it with the help of smoke, mirrors, and free booze (not unlike the phone scams that prey on the elderly and manage to extract thousands of dollars from them). And not only is it institutionalized theft, it is institutionalized classist theft, as the vast majority of the victims are from the lowest socio-economical classes of society.

dm25• 12 years ago

There only in a few cities in the US where you can gamble like that, it's illegal in most places.

Las Vegas, Atlantic City, Indian reservations, cruise ships, and casino boats are the only places I can think of that allow gambling in the US.

I'm not sure if there is a loophole for horse racing tracks or how that works.

Video gaming machines might be what you what you saw but they're really not much different than an arcade that spits out tickets. I think those video gaming machines are becoming more rare / illegal.

Our brains aren't wired to correctly calculate the fact that we're more likely to lose than win.

Same with lottery tickets, people get addicted to those things and don't stop until they run out of money. Even people in Haiti would receive a little money (meant to be used for food and other essentials) and spent it on lottery tickets.

I believe gambling is legal in Michigan[1]. It was done in attempt to bring some money in the state.

It's increasingly legal. In the northeast, you're never far from a casino.

There are many places in the US that allow gambling off of Indian reservations. There is even a casino near downtown here in Philadelphia.

You said Las Vegas, but you meant Nevada.

JeffL• 12 years ago

I don't think it's theft. It's people paying for variance/excitement. I don't think anyone really thinks they are going to gain money over time.

The interesting thing to me is that probably the same people paying for variance by gambling are also paying to remove variance via car, health, and home insurance.

Gusfoo_22• 12 years ago

(of course I have no certainty that it was truly a random process)

You do, as it happens. In order to operate, all machines must pass fairness and randomness testing. They are also under a spot-check regime to ensure there are no post-manufacture changes or defects.

It is sad that the average American citizen does not have a sufficient grasp of basic probabilities to even consider putting money in such a machine, because it means that the school system essentially fails at preparing kids for the real world.

You're not playing as an investment/to win, you're playing because it's fun. The probability of winning is a factor that affects the 'fun' element.

And it is sad that governments are encouraging those temples for theft to prosper the way they do. Because it really is theft

No, it is entertainment. It's not at all theft in any way, shape or form. You may not enjoy it, and that's fine. But other people do enjoy it.

thisjepisje2• 12 years ago

Wouldn't it be fairly easy to have a machine operate in "fair mode" during testing, and in "unfair mode" after that? Timers, secret commands and what have you.

shiven• 12 years ago

No, it is entertainment. It's not at all theft in any way, shape or form. You may not enjoy it, and that's fine. But other people do enjoy it.

Can be said for many other things too. Including things that are outright illegal, heinous and criminal. Slippery slope and all that.

NotAtWork2• 12 years ago

You do, as it happens. In order to operate, all machines must pass fairness and randomness testing. They are also under a spot-check regime to ensure there are no post-manufacture changes or defects.

Many of the machines actually aren't random. Rather, large batches of results are (semi)randomly chosen such that there's a particular distribution of results in the next several thousand (or a million) results.

unsignedint3• 12 years ago

So some thought about this, as I used to be regular of a local casino, not because I felt I had to go, just to play with cash vouchers, they used to send, maybe occasionally putting in a 10 dollar bill or two. I didn't make money out of it, but I did not lose my own money. I guess when they realized they are not making money from me, they stopped sending me those vouchers... Bummer! :-)

Those machines are really designed to salami slice players. You can play many of those machines from a penny per line, which equates to about 15 to 30 cents per play for full lines, depending on a machine. There are people who play at higher stakes, like a max bet of $2 per play, or even $5, but observing people, majority seems to be played at much lower bet of a penny or two per line, so I'm guessing they consists of high fraction of profit a casino is making from.

It's fairly easy to lose a sense of spending when you are doing literally a thousand play per hour. (At 30 cents per play, You'd be spending fairly long time to spend $20, or even $10. At this level, a typical win would get you around $2 to $5, maybe $40 if you are quite lucky -- and perhaps real jackpot, being very, very rare, $200 or so.) Those "wins" really give you the joy that you'd anticipate for the next, and a lot of time, they'd put more money in just to anticipate another win, because when they have lost plenty of money, it's about a time they will start winning, right?

Knowing someone who really got into it, one sign I started seeing from them is that they'd start making a statement like "I'm not playing it for money, I play it because the game is fun." He would play the game literally for hours per session, often visiting there multiple times a week. Usually ends up losing -- maybe the only good thing is that he'd have accumulated quite a bit of free restaurant credits.

So if you are inclined to play, here's some suggestions, though for those people who would feel these suggestions are useful probably find the best is not to play at all:

1) Set a budget -- don't bring extra money. (And don't bring ATM card/credit card if you feel like you can't resist getting extra money out of them...)

2) Record every win/lose -- I've had Google Doc that keeps track of every wins/lose every machine. Every time I cash in, I'd record, every time I cash out, I also record that, that would give me balance sheet how much I'm spending/making.

3) Bet generously -- Don't bet a penny per line, go higher. You won't go anywhere with such low bet anyways. You'll have a better chance getting a better outcome going through that $20 in 2 minutes than spending 2 hours on it. Yeah, it may only last 2 minutes, but then you have good reason (See #1) to leave at that point -- and you are giving less chance for a machine to alter your psychology.

nostromo• 12 years ago

All great tips.

Once I had a big win (for me) in Vegas playing craps. I walked away with like $2000, and each of my friends did (to varying degrees) as well.

So, what did we do? We lost it all back over the rest of our vacation. However, that big win did something chemical in my brain. I remember it very well and think back fondly of it. But I don't even remember how I lost it all back. The win is still salient and the losses forgotten.

I don't regret it because I had a great time, but all of your tips apply. 1 & 2) It's easy to remember your wins and forget your losses, so budget and keep track. 3) Go in big, because the more you roll the dice, the more likely it is you'll revert to the mean.

I'd add one: 4) don't use the machines and learn one of the table games. The odds are better and it's a social interaction, rather than an expensive video game.

unsignedint3• 12 years ago

And to amend to your 4), if you must play on machines, learn to play video poker (I personally like Jacks of Better variant) as they often have a slightly better payout, and at least you are doing "some" work :-)

Sambdala• 12 years ago

To add on to point 4, learning craps gives you both the best odds and the best social interaction.

Once you're comfortable with the game, find a table that has a low minimum bet and a high max odds multiplier.

http://wizardofodds.com/games/craps/

spilk• 12 years ago

regarding #3, most machines here in Vegas explicitly state that to get the best multipliers, jackpot bonuses, etc, you have to do the max bet.

unsignedint3• 12 years ago

Correct, and most, if not all, progressive machines would require a max bet to actually win progressive earning (or it'll be reduced to preset pay table.)

The problem of max bet is that they tend to have very high value for max bet, and (especially for casual players) it can be pretty intimidating and even unrealistic depending on initial budget.

downandout3• 12 years ago

All of this is interesting from an engineering perspective, but the reality is that casinos don't have to use engineering to get you to spend money. They rely on addiction for their income, and there's no evidence that better slot machine technology has swayed addiction rates one way or another (although TITO - ticket-in ticket-out - has made it easier to lose one's money faster). According to one study, 2.8% of the player base accounts for 50% of net casino win; the top 10.7% provides 80% of the win [1]. Without the very small percentage of their visitors that become addicts, every casino on the planet would cease to exist in short order.

Strange that adding smaller wins to slots has only just arrived, as such more complex betting systems have been proven to make playing feel more rewarding for decades.

E.g. in Finland all supermarkets and roadside cafes have slot machines, and complex betting tactics described in the article have been there at least from the 1990s. They do differ a bit from Vegas slots, as the profits go to charity and the jackpots are ~50€, but still they are carefully designed to maximise the profits on the long run.

fiatmoney• 12 years ago

I would heavily recommend the book they mention ("Addiction By Design"). In addition to the bits about the casinos, there are a lot of fascinating insights into the minds of committed slot machine gamblers.

doomlaser• 12 years ago

The straight-up gambling industry relies on whales in an eerily similar way to many f2p games.

From the linked WSJ article [1]:

"The Bwin data also offer a peek at the economics of the casino industry that only insiders normally glimpse. Among the findings is an extreme reliance on revenue from a small number of gamblers.

Of the 4,222 casino customers, just 2.8%—or 119 big losers—provided half of the casino's take, and 10.7% provided 80% of the take.

Such revenue concentration long has been quietly acknowledged in the casino industry, but the Bwin information may be the first to show it with hard public data."

Compare that to the f2p industry. From Re/Code in February [2]:

"In a mobile monetization report released today, app testing firm Swrve found that in January, half of free-to-play games’ in-app purchases came from 0.15 percent of players. "

"Some game companies talk openly about the fact that they have whales, but others shy away from discussing them publicly. It costs money to develop and keep a game running, just like those fancy decorations and free drinks at a casino; whales, like gambling addicts, subsidize fun for everyone else."

I've worked in the industry for one of the biggest online brands and can second this. It was not unusual to see a single customer spend over a million euros. We even had a couple who maxed the account limit of 5 million euros and had to create a second one.

These VIPs have their own account managers who often talk to them on a daily basis and they are given lot of gifts which are expensive (trips, luxuries etc) but nowhere near the sums they are spending.

rebel• 12 years ago

Very interesting information, but I can't tell which industry you mean as the parent was referring to both casinos and f2p games? I assumed f2p but I've never heard of account managers giving gifts in f2p games, that would blow my mind.

thisjepisje2• 12 years ago

You mean people spend millions of actual euro's on a free to play game? Sorry for stating the obvious but this is a little hard to grasp.

mercer• 12 years ago

That's interesting, and it affects how I see the f2p industry. I was never a big fan, but I figured it was fair 'enough' and ultimately acceptable practice to give people a taste and charge them for more.

But if it turns out there's a really small subset of people that spend a lot, too much probably, then it's quite possible that this business model relies, preys even, on people who have an addiction or similar problem.

With some exceptions, probably, like pay-per-episode games.

oscilloscope2• 12 years ago

An interesting experiment in gambling addiction was the Bitcoin betting site Just-Dice. There were two ways to participate:

1) Choose your bet size and chance to win. The house always had a 1% edge, reflected in the payout. This edge is much lower than slot machines in Vegas.

2) Invest in the house. Every bet affected your bankroll based on your % invested relative to the total bankroll. The house edge was on your side.

The operators of the site, Deb and Doog, encouraged anyone trying to make money to invest. They argued the expected value was positive, even though high-rollers sometimes went on winning streaks.

Despite the warnings/statistics Doog produced and the fact that there was a +EV way to play (investing), players still got addicted to the dice game itself. The rolls resolved in a fraction of a second, so some players would go on a tear and bet 3-4 times a second. The minimum payout was 1% of the house bankroll, so single bets of several hundred bitcoin were possible.

Several high-rollers ("whales") played for 14-16 hours straight in a state of intense "flow", generally winning early on and losing everything by the end. Sometimes hundreds of thousands of dollars of bitcoin (1000+ btc) lost in a single session. Sometimes coins would come out of cold storage to continue playing. The site had a chatroom where even investors encouraged the player to stop before they were ruined, but the players would generally deny addiction and continue rolling.

After losing it all, some players described the experience they were having as a chemical rush- as if they had just taken a drug.

Even users who were invested and had made sizable profits from investing were not immune to the lure of the game. Several withdrew their invested bankroll just to "play around" and fell in the same inevitable fashion.

That is an insane level of product-market fit. Can you imagine if you got to claw back all of the equity you gave up at seed and Series A, because your investors wanted your product even more?

The original founder Erik Voorhees was American but has since sold the site for 126k BTC and now lives in Panama. A few months prior to selling the site US IP addresses were banned due to legal concerns.

The minimum payout was 1% of the house bankroll

You mean "maximum" and 0.5% (after 1% was found to be too much).

"Investing" in the house was generally too slow and boring for gamblers to consider. They are used to being able to double (or lose) their stake in a fraction of a second. By being part of the bankroll they get to make a 1% return per week if they're lucky. The site ran for a year and made investors a total of just over 40% in that year.

For a gambler accustomed to making 100% (or -100%) per second, 40% per year is insignificant. To anyone else of course it's huge.

I read a paper a while ago that explained a bunch of tricky design that goes into slot machines. The odds of a particular symbol on a reel showing up aren't uniform - they use "virtual reels" behind the scenes. The reels are designed to show a lot of "near misses" where you almost win. They have a lot of partial "wins" that pay less than you put in. They "nudge" reels so it looks like you're getting closer to a win, but the odds don't change. They arrange the reels so you see a lot of "good" symbols, but not in places that actually help you.

I'm not sure this is the paper I read originally, but it explains all this in detail (ignore the dodgy domain name): http://stoppredatorygambling.org/wp-content/uploads/2012/12/...

Gusfoo_22• 12 years ago

The reels are designed to show a lot of "near misses" where you almost win.

That used to be true but is not any longer after the regulator cracked down. It wasn't the reel design (the strips are fixed) but instead the reel position value.

spacefight2• 12 years ago

"Alternatively, Schüll discovered, some video machines actually make internal adjustments if they notice that a player is on a losing streak and is reaching their "pain point." This has to be done carefully — it's illegal for casinos to change the odds in a game once a player has started playing. But, she says, casinos can reduce the volatility of a game in a way that still preserves the overall payback percentage. That's technically still legal."

Yeah, right... technically legal but that sounds totally rigged to me.

That was the only thing I didn't quite understand in the article, what does "volatility of a game" mean?

It might be realted to how you feel being on the winning/losing side while you play. If you give more wins in a shorter timeframe, the player will feel is on a winning streak even though the overall odds are the same...

say the average payout is $0.75 per $1, instead of having a 1% chance of winning $75, and 0% of anything else, they could change it to 10% chance of winning $7.5 for example

It's just changing the standard deviation of the prize payouts - doesn't affect the statistical return to player figure. So the average will still be eg 96% of the stake is won back - but the s.d. can be changed to pay out little and often, or rarely in big amounts, etc.
