The amusement device of claim 1 wherein said means for automatically analyzing, calculating and altering combinations of said symbols during said other cycle increases the probability of winning combinations of said symbols relative to the probability of obtaining winning combinations of said symbols during said first cycle.
Claim 5
Dependent Claim
37 words
The amusement device of claim 1 wherein said means for discriminating between a winning combination of symbols and a losing combination of symbols at the end of said first cycle and said other cycle is a computer.
