You can also play the progressive system with preliminary idle spins. For example, make free spins in the real money game mode. After 10-15 starts, pay attention to columns, dozens, and color. If one column, one dozen, one color, or even/odd, you can start betting the minimum on the opposite odds (two dozens, columns, or contrasting color), doubling your bet in case you lose. The "quick roll" feature is very useful here. It will save a lot of time and allow you to get longer numerical sequences. Read more about the best casino roulette in the International Business Times.
