Quite a large House Edge at roulette. Even using different manipulations with bankroll management, you will still lose it.
We draw a simple conclusion - there are no working strategies for roulette, only luck on a short distance and stop playing it.
Exactly.
Perhaps the only strategy that you can take is to be the house by investing in the bankroll, lol.
But roulette is one of these games that is all luck and no skill. And the odds are always stacked against you - make sure that you don't play American roulette with double zeroes.
