Does an electric slot machine have a table which determines the odds of getting particular combinations or does it determine if somebody wins and then picks a combination that produces the result?
Example of the first. Suppose two cherries in any of two (of three) columns is a $1 win. And we want the player to have a 1% chance of getting this result.
Cherry / Cherry / Anything - Odds 0.33%
Cherry / Anything / Cherry - Odds 0.33%
Anything / Cherry / Cherry - Odds 0.33%
Then it picks “anything” at random (excluding cherry) for the last spot.
I suppose this could be a fully enumerated table as well. Assuming the other available symbols are Bell, Seven and Lemon:
Cherry / Cherry / Bell - Odds 0.11%
Cherry / Bell / Cherry - Odds 0.11%
Bell / Cherry / Cherry - Odds 0.11%
Cherry / Cherry / Seven - Odds 0.11%
Cherry / Seven / Cherry - Odds 0.11%
Seven / Cherry / Cherry - Odds 0.11%
Cherry / Cherry / Lemon - Odds 0.11%
Cherry / Lemon / Cherry - Odds 0.11%
Lemon / Cherry / Cherry - Odds 0.11%
Example of the second.
$1 Payout - Odds 1% -> Produces a proper result.
No, I’m not planning a trip to a casino, just one of those random thoughts that pops into my head.
