Depending on who you talk to about roulette, there is often an uncertainty if it is a game of skill or a game of chance. That's an easy question to answer because it is all luck.
As with most other table games in the casino, players of roulette try to use the Martingale system to turn a profit. This system involves you doubling your bet after each loss which can see your stakes spiral out of control after a few losing bets and the Reverse Martingale System where you cut your bet in half after a win.
There are many other roulette systems people use in order to try and gain the upper hand but the main system you should concern yourself with in roulette and use consistently is the Money Management System. If you use it, you may be surprised how well it works!
There are 161 different ways to bet on the roulette wheel and with such a choice available the casino is very kind to players by allowing them to bet on numerous numbers and multiple ways. For example, you can wager on a 12 number column, a general bet on black and "odd" while placing a straight bet on the numbers 4 and 10.
Roulette is known to have the occasional "lucky" player but in reality you have more of a chance of "riding" on their betting strategies if they are "hot" than trying any "roulette system" of your own.
If you see someone winning then by all means start following their bets. The Pendulum swings both ways here so if you see someone on a clear losing streak, bet the opposite. This system works much better than any you will read about online or in the library.
Also, pay attention to the board which shows the last winning numbers, occasionally you will see runs of odd or even, black or red numbers. Follow it until it switches. It's possible the dealer isn't changing their way of spinning the wheel and it is generating this winning pattern for the players.
Roulette can be a very enjoyable game to play at the casino, but even with the $1 chips, it can eat away at a sizeable bankroll. Then again, it can also offer you a run of good luck. Remember, chance games are won when Lady Luck offers you a turn so be gracious after you cash in on your luck and then do the sensible thing and cash out!
