The formula for a binomial standard deviation is: Square Root (number of games x probability of winning x probability of losing) x average wager x (unit of wager + payout in terms of units of wager) Using our current split wager example, with an average wager of $2 over 3 games, the formula would be as follows: Square Root(3 x 2/37 x 35/37) x $2 x (1+17). High denomination slots have a higher fixed Max Bet than ordinary slots. More so, high denomination slots have higher payouts. Some slot machines pay out better when you play max bet. For example, on some 3-reel slot machines, if you hit a line of the top-paying symbols you might win (for example) 1,000 credits if you are playing a credit per.
Does anyone know the formula for calculating the SD of slot machine. Specifically the red white and blue example on the Wizzard of Odds website with a SD of 9.03 for 1 and 2 coins and 10.8 for 3.
Thanks in advance

What Is Average Deviation

Weighted Average Of Standard Deviation
I get 10.8560991087 for three coin and 9.06179830482 for 1 or 2 coins so I might be wrong(maybe a rounding error).
First calculate the return. (.865761 for 1 coin).
Next for each line of the paytable take the pays and subtract the return and square that result. multply that number by the probiblity. Using one coin a getting Red 7, white 7, blue 7:
(2400 - .865761)^2 * 0.000004 = 23.0233
Then add up all these numbers.
Then take the squareroot. This is the Standard Deviation.
