If you can take advantage of the 15-second delay before the ball is spun to do a brief analysis in order to get the right number or color prediction, then luck could be on your side and give you victory.
So that the casino will not manipulate? If there is manipulation, it would be more complex than that. As for me, I bet anytime and I do win or lose. What you will take is what you will take.
We don't know whether the casino is manipulating or not because we only play by watching the livestreaming of the game and all we have to do is place bets that we are sure will give a win.
Winning and losing are bound to exist in gambling so gamble for fun without thinking about losing or winning and when luck comes without you knowing it you can easily get victory despite the manipulation actions carried out by the casino.
What can I take?
Remember in gambling we cannot determine what we will take so everything depends on luck and courage when taking risks. So I don't agree with your last sentence.
