Roulette is the third biggest Casino game in the world because of its relative simplicity. There are two versions of Roulette: the European and the American Roulette. Let's focus on the American version. The American double zero increases the house edge.
Roulette payouts are not pot luck or simple jackpot wins, although they vary depending on what was wagered in the first place and where the chip is placed on the mat.
Straight bets yield the highest payouts. A straight bet is picking up one number out of all 36 to bet. You can choose zero or double zero. The payout is 35 to 1, meaning if you wagered you would get a nice 0 back. It's so high because you have a one in 38 chance of winning. Choose this bet on its own if you have cash to burn.
You can increase your chances but get a high payout (at least where roulette payouts are concerned) by splitting your bet. This means that you put your chip between two numbers on the board. If it lands on either of these numbers you get a 17 to 1 payout. You can take this option even further by using corner bets - yielding an 8 to 1 payout. You can use different combinations.
Perhaps the easiest method and at times the most rewarding (in the long run) is to simply bet on red or black. However this gives a low payout, which is even to how much you wagered. Say if you bet and win, you get your back with an extra .
Identical to this is the odd and even bet. Simply bet on whether the ball will land on an odd or even number. You don't have to decide the exact number it lands on though.
High bets are between 1 and 18, and low bets are between 19 and 36. Like the above two a winning bet would simply grant a payout of 1 to 1.
Of course these payouts can alter as you use different combinations - but then you decrease your odds of winning at all, and you can quickly burn through your whole bank balance.
The simplest method as outlined above is to bet on odd or even and red or black. Combine this with the Martingale system and you will eventually always be in the positive. It just depends on how big your bank balance is and if it can take a huge losing streak, or adhere to the maximum bet limit whilst taking a loss.
So the bets to avoid in this game are all single number bets and the five number bet because these types of bets have the largest disparity between true odds and actual payouts.
