DETAILS

constant bet: always bet the same amount of money
Kelly criterion: current winnings (see [1])
constant fraction: always bet a fixed fraction of the total amount of money in hand
martingale: bet the same after a win; double the bet after a loss (so all money lost will be returned after a win)
anti-martingale: bet less after a loss, more after a win (to keep going on "winning streaks" and to minimize losses on "losing streaks")
pay out odds: uses decimal odds form (2.0 means if you stake 10 dollars, you get 20 dollars back, including the 10 you bet)
25 trials: gives you the average money won by 25 people playing the specified number of games
Roulette and other information from [2] and [3].
