A little while back I wrote a post explaining what a par sheet for a slot machine is and what it says and what its information means. But it seems that there might have been a bit of a misconception about what the information means and what it means in practical terms.
First a quick review. A par sheet is a set of sheets with performance specifications about a specific slot machine. These sheets help casino staff know whether a slot machine is performing within the range that it is supposed to. But these sheets, while revealing odds information, do not impact the actually playing of the slot machine.
One of the details on a par sheet is the machine’s payout percentage. This is used by casino staff to know if the machine is paying out as it should. For example if a par sheet says that a slot machine is supposed to have a payout percentage of 95% and it is paying out at 80% something is wrong with the internal workings of the machine. And it needs to be removed from the floor for repair.
Another detail offered on a par sheet is the odds on hitting the jackpot. A par sheet can say that there is a 20,000:1 chance of a slots player hitting the jackpot. What slots players need to understand is that this does not mean that if you spin the reels of this slot machine 20,000 times that you will win the jackpot.
The reason for this is because of the Random Number Generator (RNG). Each spin is independent of the last. For each spin the RNG will pick a combination for the outcome of that spin. The RNG does not count up to 20,000 and award a jackpot; that would undermine the randomness of its purpose.
What the par sheet is saying that out of all the combinations there are 20,000:1 odds. It is just an odds statement, not a secret to how to beat the machine.
Even if you get a chance to see the par sheet of a slot machine only regard it as interesting information. Do not regard it as the key to beating the machine. True it will give you a better insight into a slot machine—for example if one machine has a better odds on hitting its jackpot then another slot machine, then it makes sense to play the one with the better jackpot odds.
But do not believe that those papers will reveal the secret nature of your favorite slot machine. Remember that they are only performance guidelines for casino staff to use to tell if a slot machine is performing as it should.
