Trust me, all those strategies are just gamblers fallacy. No matter what strategy you apply, you will cannot beat the house. You will lose against the house in the long run. If all those strategies actually worked, then casinos wouldn't exist anymore. They would have been wiped clean by their users. Remember, casinos implement various rules so that the house never gets cleaned. For example if you play using martingale strategy, after making losses, you will eventually reach a point were you won't be able to double your bets anymore because of the bet size limits the casino may set.
