~ Or maybe to be fair, half truths, you cannot apply Martingale to poker, that assessment is false, it works perfectly in roulette and basically betting on red or black, Martingale essentially requires a 2:1 or 1:2, otherwise is any other strategy.
I never heard or seen someone using Martingale in poker games, if there is, this is the first time. Martingale is a devastating strategy if we don't know the right time to stop and reset. It is indeed good to use in roullete but still if we happen to have a bad session, it can still make a huge impact in our bankroll.
Martingale strategy can be used when playing
Video Poker. I'm doing it from time to time, and it's fun. You should try it. As it is always with purely luck based games, there's no guarantee that you will not lose your entire balance following this strategy, but if you are ready to stop in time, or your entire balance is not that big, try it, starting from the lowest bet possible, of course.
