1. Never jump from table to table as you might leave your luck behind you.
2. The following strategy will work for sure: when you see your favourite number hit at least 3 times, then change the number and play for like 5 spins to get the change.
3. Gambling is not a good way out if you are in a bad mood. If you go to casino with such a mood, you will only be disappointed because karma will join your mood and you will win nothing. Gambling goes well with a good mood.
4. Be sure you don’t fight with your woman or man at the table as this can only bring you bad luck.
5. Everybody has a lucky number, so stick to them.

A well-known betting system in roulette is the Martingale system. There are a lot of variations of it. The principle is following: when you win, you pocket your bet. But when you lose, you double the size of your previous bet.If you win that will guarantee you get back your previous loss and one more unit.And so on.
The Martingale System works great only in case you have an infinite bankroll and no betting limits.
Another popular roulette system is the d'Alembert system. This system assumes that after a win, a player is less likely to win again.So after a win, you subtract a chip from your bet. The d'Alembert system also assumes that you are less likely to lose after a losing spin, so in that case, you add a chip to your bet. The fact that the roulette wheel has no memory and each spin is an independent trial with exactly the same odds of a win or loss is the previous spin is a weak point of the system.
