Here is how to design a single reel slot machine
with only two outcomes and with payback = 95%.
Let L and W represent the # of losing and winning symbols respectively.
We need to solve the two following simultaneous equations to
determine the values for L and W.
1) L + W = 100
2) L - W = 5 or L = W + 5
substituting W + 5 into equation 1) in place of L gives:
W + 5 + W = 100
which simplifies to:
2W = 95 or W = 47.5
and therefore L = 52.5
Since you physically can't have 47.5 or 52.5
symbols on a reel, double those values to 95
and 105 respectively.
In Albert's example below the payback is actually
100/105 or 95.238%.
G'luck all,

He states that as soon as you hit the bet button (or pull the handle) the RNG selects the outcome for each reel and the corresponding symbols appear on the screen. However, he repeatedly says that the machine's EPROM chip determines what payback % the machine is set at, and the Casino Manager can change that chip at will.
