Slot Machine Par Sheet

Posted onby
Welcome to VegasMath. If you need world class gaming mathematics for the casino industry or social media games, you’ve come to the right place.
Whether you’re a startup with a great idea or an experienced company who simply needs better gaming math, we can deliver on time and on cost. We specialize in the design and development of mathematical models for slot machines (Class III, Class II, and Class II conversions), bingo, keno, video poker, scratch cards, pull tabs, table games, side bets, skill games, gaming promotions, new games – you name it. We pride ourselves in the timeliness and quality of our work, along with the support we provide.
We can work with a high-level idea, a fully documented formal specification, or anything in between. Our math models and PAR sheets aren't just numbers – we can also supply design assistance and suggestions to make your game have the best possible player experience. A game might be mathematically accurate but provide a poor player experience resulting in games sitting unplayed for hours, if not days. We prepare player simulations that not only identify such cases, but quantify them.
Using material prepared by our own Diana Gruber, our colleague Guy Hasson has created a seven-part presentation explaining how to read a PAR sheet. Guy's presentation uses one of Diana's PAR sheets for a relatively simple slot machine, and he has posted each part of the presentation on LinkedIn®. Check out Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, and Part 7.
Please explore our website to learn more about the services we provide, or contact us to let us know how we can help with your gaming math needs.

  • Your post on par sheets (under the hood) suggests that slot machine programming uses the expanded reel strip (virtual reel) to control (or program) the desired payback%.
  • Every slot machine at a casino uses something called a par sheet which provides information about the odds for each tile on a reel. Each reel is weighted to reach a certain number of spins for every time a certain tile is generated by the algorithm.
So I wrote a Basic program on my iphone to calculate the return for Quick Hits Platinum Black & White Sevens. I used the odds Mission linked to in an earlier thread. Still haven't found a 100%+ QH game, but I really haven't been looking. Just writing the program was a nice mental exercise. I would really like to see some Par sheets for some other current progressive slots to do the same thing and calculate if the game is a positive play. All the slot websites I've checked (IGT, WMS, Bally, etc.) require you to have some sort of job with a casino to see their Par sheets on their websites so I'm outta luck there. Any suggestions?

I think you have two of my stories mixed up. To make a long story short, I don't have any PAR sheets I can legally share and lost my legal fight over another similar matter. More on that when I write about it in May.
It's not whether you win or lose; it's whether or not you had a good bet.

Dr Kevin A. Harrigan and Mike Dixon, University of Waterloo, Waterloo, Ontario, Canada got PARS sheets from the Canadian government for their article entitled.

There are some PARS sheets for old games that have been posted online (see my blog) but not progressive games.

There are some PARS sheets for old games that have been posted online. I am not sure what the big deal is about them, as the tricks are not overly difficult to figure out.


I have a whole box of PAR sheets but don't want to get sued for publishing them. It is really no big deal to have some. I already explain how some slots are designed on my Odds site much more clearly than any PAR sheet.

Thank you paco, I have read that before and it is a good read.
Wiz- I am anxious to hear what happens in may. I am jealous of your sheets. If I had them, I would make a professional slot player app with calculators for the more common progressives. Throw in the mystery progressive target point calculator with some other gambling tips and ouila! You have professional slot playing for dummies.

Darn, but I look forward to reading it. I was all ready to pay $20 for the legal defense fund.

Is it out of order for me to ask if the FOI case was against government regulators or were you bringing it against the manufacturers?

My PAR sheets are for games from the late nineties and early zeros. As far as I know, none are progressive.

You, sir, are out of order! Sorry, I've always wanted to say that. The case was against the Nevada Gaming Control Board, and I lost. The story is pretty boring; don't get your hopes up. After a lot of legal expense on both sides the judge ruled against me without stating a reason.Slot Machine Par Sheet

PAR sheets ? Strips, straps and stops...?
What is relevant disclosure?
You tell a mesmerized drunk: you put your money in here and you press this little red button here, then lights flash and you either win or lose.
Is a casino required to disclose how bright the lights are or how sultry the recorded voice is? The only disclosure issue is the stats of hitting it big or not hitting it at all.
Such disclosure now appears to be made as a percentage basis over a non-defined 'long term'.
