As far as video poker goes, the machine is playing no different than a physical dealer would. The payback percentage is set by changing the amount awarded for any particular hand. So if you spend a while learning about the different games, you can tell which machines are set to a higher payback by looking at the pay table. Good to know, thanks. Yes it shows the remaining cards afterwards, but I often wonder if all of them were predetermined, or if they were just fucking with me.

The other day I burned through 20 bucks on there. Luckily I noticed the machine next to me, someone had walked away with 1 25cent credit left in it, and I ran that back up to 40 bucks. Okay, if it shows the remaining cards afterwards, then they were placed and your choice affected the outcome. If the cards were NOT shown, then your choice didn't affect the outcome. This comes in to play most often during slot machine bonus rounds. And they were fucking with you.

Sounds like you've got optimal play memorized. Hope you've got a club card so you're getting comped on amount bet. Try to find a place that comps on amount bet, rather than coin in. Man if I ever found any evidence of them doing that, I would have to get their license taken away I don't particular mind that the house always win, but cheating is another thing.

It's not cheating, it's just that your bonus would have been predetermined, and picking between different items on screen is really just eye candy. There's absolutely no way a casino would use a machine that cheats, and there's no way a manufacturer would sell a machine that cheats. Both companies know that it would basically shut them down permanently if it happened. To what extent has your programming for players' clubs involved card counters or other advantage players?

Casinos really take card counting personally, but they often forget to wipe out the comps that card counters have earned. Is this an issue you have worked on? Do you deal with issues having to do with comps e. Most casinos use pit bosses to identify counters. Once they're identified, they're just flagged in the back end system. There are a couple IAMAs here from counters and it didn't sound like they would try to use club cards while playing. Are you asking about points earned based on play, or about comps given?

It looks like you're asking about comps given. If so, well, once a casino gives something to a player, they can't take it back. Doesn't matter if it's a free meal, a tshirt, a car, or a small pacific island. Sounds like you guys were pretty on top of the whole counter issue. Makes sense the way you lay it out. Can't imagine a counter would last too long there.

Environment - depends on the department. Dress code - relaxed tshirt and jeans. Work culture - depends on the project. How much do you make? How many years of software development do you have? Other sectors you've worked in? What kinds of bugs can arise from your systems? Besides tasks surrounding RNG, what exactly is there to do? Do you write software for new machines? Upgrades for old machines? It seems like once the software goes thru vigorous testing it's ready to go live and the job is done, what more is there to do?

Can you reuse bits and pieces from other systems? You want my earnings? Not going to say. As far as I know, all of us make a decent wage, but nothing spectacular.

OS and IDE depends on the project. For what it's worth, I prefer Python and Django. And I hate Java. Ultimately, they're all just tools - we do the best with whatever environment we have to use. There isn't really an upgrade path for software. If a new version is released, the earlier software on the machine is wiped out and overwritten completely.

Currently I write software for undisclosed projects. The job is never done. We are always looking for new ways to engage players and make sure that they enjoy their time on our machines. I have an idea. Make the machine pay less money more often. When I play, much like you I don't play to win because I know the odds. I play for the free alcohol. You're looking for a low volatility game. There are a couple of video poker forums where you can read up on which variants have the highest payback percentage.

And yeah, your point about length of play is a good one. There's been a lot of thought about that in the industry lately. Lately being the last 10 years It seems like lately manufacturers are starting to understand this again and have started putting more emphasis on fun rather than simply extracting as much cash from a player as quickly as possible. I'm a software engineer - how did you get a job writing this software?

It's always seemed pretty interesting, which companies would I need to apply to? First off - you must have a clean criminal record.

It sucks, but there's no way around it. I got the job because I was a SQL guru and fit well into the exact position they were looking for. Since then I've grown into more areas and responsibilities.

You should apply to all of the slot manufacturers if you want to write code for games. You should apply to all of the casinos if you want a job working on apps and backend software. Your best bet is to find a good recruiter in Vegas. They will know the industry and where you'd be best placed. Send me a private message and I'll see if I can recommend a recruiter. I do that so I can better understand what our competition is up to.

And most importantly, I do it so I can see things from a player's perspective. Maybe I sidestepped your real question I don't gamble, since I know the odds. But I do play any and all machines just so I keep in touch. I lose a lot of my own money, but I figure it's worth it to really see things from the perspective of a player. Thank you for that.

I'm going to tell my mother-in-law about this comment, since she's gambling away her grandchildren's inheritance. I would encourage you to look into gambling addiction resources so that you can present her with some reasonable discussion, rather than a blunt attack on her lifestyle been through this before.

For instance, any result of a wager must be physically written to disk and guaranteed not to be cached in the drive's cache before the result can be displayed to the player. You can look at the NGCB website for the specific regulations. But basically, the slot machine must never ever lose information about the previous 30 I think 30, it's been a while since I read the regs wagers and outcomes.

A significant amount of the engineering that goes into a slot machine is there specifically to make sure it cannot cheat a player out of a valid win.

Also, logging is extremely important. According to the regs, the machine must be able to recall everything about those past 30 games. So if there's a dispute, a regulatory agent can walk up to the machine, plug in a key, and play back everything that happened on the machine, including every button or screen press the player made, all RNG results, and more.

Which jurisdictions do you write code for? The logging I have to do isn't nearly so in depth. I have to recall the last 10 game outcomes, each of which has to be able to display 50 subgame outcomes, but that's it.

We have meters and things we record but there's very little data involved in an actual game record and it's almost all tied to the game result. Did you ever write some super secret code into the software that only you knew? And in such a way that you can win money every time, using your secret method? Nope, never even considered it. The only person that did that back in the 80s, I think is currently in prison. The industry doesn't attract the kind of people who would considering doing so. Kind of boring - no intrigue or excitement.

But you could if you wanted to right? And if so, is it possible to bury the code so deep that no one will know? The guy who did it in the 80s was able to do so because back then a machine could be developed by a single person. Those days are gone. These days the software is complex enough and most manufacturers are paranoid enough such that there are at least two people who see and understand every bit of code that goes into any machine.

The chance of both people and a few others in the process risking serious prison time is pretty much zero. Ron Harris did it in the 90's and he's out of prison now. What I don't get is, he was smart enough to do all this, then he bet a run on Keno, which is statistically basically impossible, which led to his arrest. The silly thing is, Keno pays off full for a run, so a run is for idiots only.

That's the guy I've been alluding to for a while. Forgot that it was in the 90s - I'd thought it was the late 80s. I can't think of any mistakes you could make that would lose a casino money. Most mistakes tend to fall in their favor. And if you look at other threads on reddit from people that work in casinos, there's really no threat of violence from a casino.

If you abuse the casino, they just ask you to leave. If you do something criminal, they just hold you in a back room until the police arrive and then turn you over to them. I meant a mistake such as writing a unit test which doesn't actually test the right thing, and consequently introducing a bug which causes anomalous payouts. Things like that might easily look malicious even if they are not.

In my case I would probably get fired and gain a reputation pretty quickly that would mean I wouldn't be able to find a job in the industry again. I know of at least two companies that had things like that happen. Both honored the win, paid out, and then had discussions with their insurance companies. I don't know the fate of the programmer in either case - but in one of the two I'm fairly sure nothing bad happened, since it wasn't really caused by any one person's mistake.

In practice, though, they'd rather get trouble makers off the property. So a belligerent drunk might get held down below if he's causing harm to other guests, but most likely they'll just call a cab and pawn the problem off onto the cab driver. There are plenty of places in Vegas for non gamblers. Even in the major casinos, there are showrooms and restaurants, and concert venues, and plays, and etc etc etc. Out side of that, Vegas is a normal city. We have all the stuff most other cities have.

Except a sports team. There is a while tourism and convention industry. I don't gamble and I still enjoy living and working here. A lot of people complain about a lack of culture and community, but it always seems like those people aren't actually getting out and trying to find it. Plus I've always found Vegas to be a friendlier place than anywhere else I've lived - it definitely doesn't suffer from the Seattle Freeze. Also a great area for offroading, shooting, hiking, climbing, camping, and just about every other outdoor activity.

I don't exactly like living in an area where our entire economy is basically dependent on discretionary income. Tourist destinations are always slower to recover than the general economy. The big concern is Macau And I will give Goodman credit - he tried to expand the economy by encouraging manufacturing and high-tech businesses in the city. And there are a lot of small custom manufacturers here.

It's not a bad place to set up shop. And it's not a bad foundation for an economy, just have to save up to be able to wait out the lean times. Unfortunately, it looks like most major businesses here haven't done that. If you were going to go in to a casino and try to actually win some money, what would you look for as external signs to choose a machine? If you have a casino nearby, you should look for the video poker machines and start reading through some video poker forums for tips.

You won't win money, but you can get a lot of comps. If you're just an occasional visitor, I'd either get really good at poker or learn how to count blackjack. If you're in an area with multiple casinos, the best you can really do on slot machines is to compare the payouts between two machines with the same game. Look for one that has higher payouts. That will give you a better chance, because the machine is set to a higher payback, but still won't guarantee anything. It's all still completely random.

Can you program in a auto-win code, like in Ocean's Thirteen. Maybe something all redditors could remember, like the konami code? But no, there's no way that would or even could happen these days. There's way too much oversight for anyone to try it. And like I've said before - no one working in the industry would ever even think about it.

We all prefer our careers over prison. And to expand a bit - the background checks for people writing slot machine software and even back of house software such as the accounting systems can be pretty intense.

We make jokes about it, but some jurisdictions actually do a background check that's comparable to a government top secret clearance check. I used to work on the accounting integration systems for many casino's in CA and the front end kiosks used by staff. No background checks for anyone at our company. But that was in And maybe it's different for Indian casinos. CA really only pays attention to GLI, and that's more of a suggestion than a requirement.

Anyway, not surprised that you didn't have to do any background checks. Things are different in different areas. In a lot of areas, um, things are a bit fast and loose - those aren't areas where I'd be willing to gamble. Could you kill two birds with one stone and get a Secret clearance at the same time? If they're gathering the information anyway, why not? Sadly, the government doesn't work that way.

But at least I know that if I ever need a top secret clearance, I can get it. In the late 90s there was a lot of research done to try to understand why people like playing slot machines. Most of that research was ignored Right now the big buzzword is Farmville.

So everyone in the industry is trying to understand how that works on a person and leverage it. Yeah, we're all a bit slow. Above my level, I don't know. I can't really say what they do or don't know. However, I do know that amongst my team, most of us have read at least one book dealing with the psychology of gaming.

And thus we work towards meeting those goals. Disclaimer Everyone at my level see's the future coming. So we're not worried about hooking players. We're most concerned with what we can do to make the experience fun for a player. And part of making something fun is to engage the player and reward them for playing.

I spent a few months doing front end interfaces for casino games. My take on it was that it's a unique culture. Lots of money thrown away rather than running a coherent company. No leadership, no communications or collaboration. Most everybody in the place was a sad old man with some sort of addiction. People came and went, often without titles This is Bob, he's the new Tim. Random trips and random showing people around.

The company would pay for things you wouldn't expect, from oil changes to all the free power drinks and jerkey at work. Yeah, there was a time to when just being in the business guaranteed profits. That's not so true today.

I have no idea where you worked, but what you describe is in no way the norm. It kind of sounds like you were working with a company we know about I worked for U1 gaming in Montana. They make machines here and were just breaking in, in Nevada. The same guys made up Montana Video Lottery and another short lived company.

I left there with such a bad taste that I probably wouldn't even think about going back into casino games. Anyway, a lot of companies are managed pretty poorly. It sounds like you ended up dealing with a crappy company. Not much I can do for you other than hope that you found a better place to work.

I did, and considered myself lucky that I wasn't tied up in legal problems for years like others that worked there. Two different sound guys ended up taking them to court over issues. I've made video games for a number of companies and this was the last. I now animate for scientific out reach and make interactive educational software and am much happier. That's a pretty crappy company, but it's good to hear that you got out.

Happy to hear that you're doing well now. I've heard that slot machines are often programmed to first figure out the amount a customer wins, and then displays an appropriate front end based on that. Rather than having actual random 'wheels'.

Nope, that's completely false. Every spin is independent of the next. Slot machines don't analyze your behavior - there's no reason to. I don't think you understood me correctly, or I might of written my question wrong. I know each spin is independent of each other. My question was how an individual spin is logically programmed. Let me try again, with an example this time. Once this value is determined, the machine than displays the pretty picture that shows a win of that size.

So it determines you won 25 credits first, and then shows that you won that cause u had 3 lions or whatever. And you're correct as far as the individual spins goes. The machine determines and records a win or not before it presents it to the player. I think most slot players would be surprised to learn this. I imagine they are naively believing that they really were so close to winning a jackpot. Do you see any ethical issues with this?

I think slots aren't fun but am okay with it, but wish more slot players understood this fact of how the game actually functions. See my post above where I wanted to help someone that sounded like they have a real problem. I'm no more conflicted than loggers, oil rig workers, car designers, hair stylists, or tele-tubby actors. That's why I put Larry's name in quotes. You should be ashamed of yourself trying to sully his good name.

By making it appear as if he's wasting time in the internet when he could be working? What kind of software dev process do you use where you work? Is it a 'hip and modern' agiley sort of process or more cowboy like? More specifically, do you unit test slots software? Anything else interesting or unusual in the process compared to other development jobs?

Different manufacturers have different processes. I can't go into too much detail about ours, except that unit tests, functional test, and math verification tests are all extremely important to the process. What would you say the best way to test random functions is? I asked in more detail at stackoverflow but never really got an answer I was happy with.

If you're actually facing a real world scenario where this kind of thing becomes important, send me a private message - I'd be very interested in helping out and learning. That's not really my department. But I have read the regs, and the requirements for physical security of the machines are impressive.

They have to be able to stand up to some pretty severe abuse and keep operating, without being affected by external conditions. I'd say that physically, slot machines are far more secure than ATMs. There were a couple threads on reddit not too long ago from card counters that addressed these far better than I can. There are a few. I can't remember any specifically - they're pretty rare and mostly nonexistent these days.

And they would be display only. Yeah, everyone knows about them. Send me a private message if you want to discuss further. Have you been following any of the crazy casino busts in Alabama? For those of you outside of "Real sic America" the governor is on a holy crusade against casinos. Yes, I have been.

I try to keep up on any news that may affect the industry I'm in. Yeah, I'm a programmer, but it doesn't hurt to be aware of the wider implications of the world that might affect what I'm doing. I think I answered this above. And that doesn't count the database languages Hope she enjoys the job, and I hope it keeps her happy until she's retired and can sit back and watch other people do the job.

Ive been told if a casino is not paying out enough based on regulations that at the end of certain time frame month, or 6 month, or 1 year that they will let a bunch of people win to even out the books. Do they have any control over how many people win or not? That's news to me. I don't want to hurt their business, but reservation casinos are kind of a different world.

All I'll say is that in a regulated environment like Vegas or Atlantic City, that would never happen. Same with slot machines. For reservation casinos , they have to give out at least X percentage of what they take in right?

This is what I was told , they have a minimum that they have to give out. I'm not going to comment on reservation casinos.

Just keep in mind that they try to operate as a sovereign nation. I've done some research into them, but never written any. It's an entirely different market, with a lot of interesting twists.

I was watching a documentary once about gambling and the use of computers to generate random numbers. The program went into great depths into whether a not a computer could be random, because at the end of the day computers work on patterns. My question to you is, can a computer generate a completely random number? Or does it create a number by utilising a complex algorithm that makes it look random, but is essentially following a complex pattern?

That's a difficult question to answer, since we're starting to get into some areas of high theory A computer can generate a truly random number. If done correctly, a random number generator can be truly random.

In practicality, part of that randomness relies on the player. People are pretty random, so why not use them for a seed? I hadn't thought about it in this way before. Huzzah for exploiting the randomness of people I say! Change machines after a big jackpot -- the machine won't be due to hit again for some time.

From a money-management standpoint, it makes sense to lock up the profits from a big hit and move on. But the machine is not "due" to turn cold. In fact, the odds against the same jackpot hitting on the next pull are the same as they were the first time. Play a machine that has gone a long time without paying off -- it is due to hit. Slot machines are never "due. Casinos place "hot" machines on the aisles.

This belief is so widespread that end machines get a good deal of play regardless of how they pay. It is true that not all machines in the same casino are programmed with the same payback percentage. And it's true that casinos want other customers to see winners. But slot placement is more complex than just placing the hot ones at the ends of aisles. The payback percentage is lowered when the crowds are bigger and demand is greater. It's not that easy to change a machine's programming.

Changing the programmed payback percentage requires opening the machine and replacing a computer chip. That's not something to do cavalierly. When the cycle completes, it will remain true to the hold. Mind you, the length and number of bets is also random. Software that only allows the machine to payout a specific rate.

The machines are all tested prior to hitting the casino floors, including the card shuffling machines, and roulette wheels. Everything is tested and recorded to make sure there are no flaws. Occasionally, there can be glitches in the machine, software, etc that can cause the machines to reset and payout more than what they should. Within a short period of time, that machine or equipment will end up being replaced for a new one.
