But, how can I calculate the expected number of free spins for the game?Is it (5+7+9)/(1-(p_3*5+p_4*7+p_5*9))? Recent Searches The simple formula is *. You start with 10, but free spins can earn more free spins, infinitely. In that case, the expected final number of spins is n/(1-n*p), where n is the number of free spins earned per bonus, and p is the probability of the bonus per spin. In the the Atkin's case, the bonus probability is 0.011185, so the expected number of free spins per bonus is 10/(1-0.011185*10) = 11.259335.
