If you flat beta and get out when you double or lose everything what are chances at Roulette.

I think both strategy the maths can be done and used to decide.

But I suspect t the best way to double is bet all on black at one go you have a 48% chance of doubling that may be better that flat bets or Martingale.

Actually if you want to play only one game and bet all in, the best bet is to bet on Banker in baccarat.
