This method I made and it gets me really well on the game. what you wanna to is this:
Play with $5 on 49% double the money x2 every hit
If you lose increase the bets x2 to recover the lose:
Lose $5 >>> Bet $10 > Lose $10 >>> Bet $20 >>>>> Lose $20 >>> Bet $40 >>>>>> Lose $40 >>>>> Bet $80
Hit! get the $80 Bet $5 again and if you win you continue and continue to make $5 untill you lose
and increase your bets to recover
you will never have 10-15 times you miss bet on %49 so you will always recover your money back
and hit hit $5 after to make profits
This is simply martingale and it seems you are kinda new in gambling. To tell you the truth you can have 20 or 30 reds in a row or even more that could make your balance into zero. No matter how big your bankroll, martingale will drained it if you play for a long time. It's the worst strategy.
First it looks attractive using this method when you are new and use it in a short time. just leave in a few minutes, big chances your balance will run out because of that strategy. I myself have no special strategy, just play with fun and when you win,j ust stop. it's not a strategy actually but just little tips

Many newbie gamblers will fall for this strategy but soon they will realize it will make their funds Nil in short passage of time.
Even if you are lucky and keep on winning it before your balance exhausts, the winning amount is also not a big one.
