Great Martingale Calculator. This app computes bet progressions to any kind of bets.
Maximum and minimum bets refer to the casino limits. Payment of the bet is in the format X:1 where X is the amount of the payment e.g. 2:1 (roulette colour bet), 35:1 (roulette straight bet). Please be sure the bet data is in format X:1, if not it is necessary to convert it. e.g. Sports bets are in decimal odds (3.5, 1.6, 2.2 etc) you just have to rest one unit: 3.5-1=2.5 payment bet.
