did you every wonder how a machine can have a 95 6 hold
Did you every wonder how a machine can have a 95.6 % hold?

Or any other specific number above 75% in Nevada

Well it’s a function of a formula that says

  • The percent is part the probability of winning
  • The amount you win
  • The probability of losing
  • The amount you bet

another stat reminder
Another Stat Reminder
  • If I say what is the probability of tossing a head on a coin….you say ½
  • If I say what is the probability of getting a tail on the first toss and the second toss of the coin………..
  • You have to multiply the probabilities and we know it is less likely to happen
  • ½ * ½ = 1/4
  • On that old machine with 3 reels, 20 symbols the probability of hitting 3 lemons is……
  • 20x20x20 = 8000
slot machines

Today’s machines can have hundreds of virtual reels:

More than 300, and they don’t have to be the same number on each reel.

now look
Now Look

So now we have say 256 symbols per reel…and the jackpot is….

256 x 256 x 256 =



or a slight change to 300 symbols per reel is

Or a slight change to 300 symbols per reel is:

1/300 x 1/300 x 1/300 =
