DO NOT PLAY ON THAT GAME. MAX BET IS 43 COINS. ITS A FAIL SAFE LOSS FOR US AND A WIN FOR THE OWNER. well you can donate more LTCD so the max bet will be higher, the max bet calculation is done by this formula:
total funds available / 100 = maxbet
EDIT: game is not rigged, but its protected for the martingle system, so if you use it there is no garantee you will win!
