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. This "split" bet pays off at 17-1. You can bet on three numbers at a time, paying 11-1, four numbers (8-1), five numbers (6-1) and six numbers (5-1) Simple as that. You can buy in and play with standard casino chips, but each table has its own set of special "wheel chips." Wheel chips, which come in several different colors, are used so that the dealer can distinguish among all the different players' bets on the layout. When you go to exchange your cash, or casino chips, for wheel chips, inform the dealer of the denomination (within the stated betting limits) that you want your chips to be. Say you want each chip to be worth $1. Unlike other casino games where bets must be kept separate, Roulette players can stack their bets on top of one another's. 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. The zeros are called house numbers, because when the ball lands in one of them, the casino collects all bets except those placed on the zeros. The casino advantage on a double-zero Roulette wheel is 5.26%. 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. It has a whopping casino edge of 7.89%. Some casinos provide reader boards that track the last 20 to 30 spins. While interesting to observe and look for patterns, they don't provide much information of practical use. Roulette is a game of independent trials, which means the ball has no memory of what has occurred in the past, and cannot become more predictable because of prior results. Since the casino edge on both the inside and outside bets is the same, it doesn't really matter which you choose to play.

Roulette Tips

The only excuse for not playing the standard European version is ignorance, because the American version produces a higher House Edge.  European roulette does not offer the 00 on the wheel, thereby taking one more bet out of the equation, and lowering the House Edge to approximately 2.6% - the lowest edge at the table.

Tip - Place more even money bets than other wagers

The even money wagers will give the player the lowest House Edge at online roulette.   These are the Red/Black, High/Low and Even/Odd bets, which have a 50/50 chance of winning. 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.
