The invention of the game that we're familiar with today is generally attributed to the French philosopher and mathematician, Blaise Pascal, who is credited with originating the probability theory. But forerunners of Roulette, basically carnival wheel games, were in use throughout Europe, as early as the mid-1500s. They fall under one of two categories: "inside" bets and "outside" bets. Inside bets are made on the individual numbers, one through 36, and the zeros. Betting on a single number is called a "straight-up" wager. Say you bet on number 23. If the ball drops into the number 23 pocket, you're paid off at 35-1. Those are all the inside bets. Outside bets are the wagers made on the outside of the layout. These are the bets on red-black, odd-even, and high-low. If you place your chips in the even box and the ball drops into the number 24, you win. The first 12, second 12 and third 12 all pay 2-1. If you give the dealer a $20 bill, he'll give you back 20 wheel chips worth $1 each. The player next to you might be betting with brown chips worth $5 each, and the player next to him might be using white wheel chips worth $25 apiece. Wheel chips allow for a practice that's unique to Roulette: the co-mingling of different players' bets. It indicates the lowest wager allowed on any outside bet and the lowest total bet inside. The chip minimum tells you the least amount you can bet inside on a number. You CAN'T exchange them anywhere else in the casino, not even at the cashier's cage. Most Roulette wheels in Las Vegas have two green-colored pockets, one displaying a zero, and a second with two zeros. On occasion, you'll encounter Roulette wheels that have only one zero. The house edge on a single-zero wheel is only 2.7%. The double-zero game has one bet that you should always avoid: the five-number bet on 0, 00, 1, 2, 3. While interesting to observe and look for patterns, they don't provide much information of practical use.

Roulette Tips

Keep in mind that all the bets on the roulette table naturally return a 5.25% Casino Advantage (except the five-number bet), although there are some situations when this advantage can be lowered to 2.6% and 1.3%.  With this in mind, here are the best non-system related tips that will help a player hold out at the roulette table:

Tip - Play the European version of Roulette

Most online casinos will offer both the American and European versions of roulette. With these bets, a 1.3% House Edge is obtainable, and will help a bankroll hold out longer with more positive return.  Additionally, it is only the even money bets that qualify for the "en prison" rule (see tip #3), which will bring the House Edge down even more.

Tip - Play a roulette table that offers the en prison or la partage rule

With this rule in place, which not all casinos offer, (and so therefore is a subject worth looking into when picking an online casino to play roulette at) the House Edge can be brought down to 1.35%.  It states that when a 0 (and 00 for the American version) is landed by the roulette ball, all even money bets are not lost, but are rather afforded the opportunity to stay on the board for the next bet, or be taken back by the player.  In the long run, this rule can be the deciding factor on whether a player ends in the red or not.  It may not even come into play during a round of roulette.  the fact that it can be exercised is quite reassuring, made evident by a House Edge reduced by half.  Las partage, called the Surrender rule, governs even money wagers in the same fashion, except that it returns half of the wager, thereby returning a 2.6% House Edge.

Tip - Do not place the five-number bet

The five-number bet, simply put, gives a House Edge of 7.3%.  This is the highest casino advantage of any other roulette wager, and should always be avoided.  With 5 to 1 payout odds, a player is better off taking the 8 to 1 payout on a corner bet.

As one can see, an approach to playing roulette can still be based on the numbers, as few as they might be.  The Casino advantage and odds still change from bet to bet, but do so in such a way that making a wise wager choice is easy to not second-guess oneself over.
