Know a bit about the reverse martingale strategy. The reverse martingale is increasing your bets when you win and decreasing your bets when you lose.[2] The idea is that if you go on hot streaks, you'll increase your earnings, and if you hit a dry patch, you'll limit your losses.

Find a roulette table with a small minimum bet and a high maximum bet. Again, the strategy is basically the same as the martingale, except reversed.
3
Bet a small amount on black or red, even or odd, 1-18 or 19-36. For the sake of example, we'll assume you made a red or black bet.

Wait until you hit your color. If you keep losing, continue betting your very small amount.
5
When you've hit your color and won a bet, double the bet on the same color for the next spin.
6
If you win, continue doubling your bet. This is the amount that you might bet if you won 14 straight bets:- 1 - 2 - 4 - 8 - 16 - 32 - 64 - 128 - 256 - 512 - 1024 - 2048 - 4096 - 8192

If you lose, move back down to your original bet. Using
the reverse martingale can be risky if you lose. As soon as you lose,
you've lost your entire earnings. To make the reverse martingale
successful, then, you need to ride a streak of wins and quit before you lose.
