A session ends when the ball lands where it may, and the dealers clear the board of losing bets (and pay winning ones of course) When the new session starts you can put your chips down where you want to bet, and you don't really have to be in a hurry. The inside bets are made up of specific numbers or combinations of numbers within the number layout, or along the border of it. Split bet - you can place a single bet on two individual numbers if those numbers are beside each other on the table layout. Corner bet - lets you bet on four adjoining numbers. Placing your chips at the point where four numbers meet will indicate you want a corner bet. This is different than inside bets, where the total of all of your inside bets must meet the table minimum. Odd or Even - similar to the red black bet, this even money bet is based on whether the resulting number will be odd or even. Low or High - this bet lets you predict whether you think the next number to come up will be part of the range from 1 to 18, or part of the range from 19 to 36. Columns - at one end of the set of 38 numbers are boxes with the words '2 to 1' written in them. Dozens - a bet very similar to the columns bet, dozens lets you place a bet on either the first dozen numbers (1-12), the second dozen (13-24), or the third dozen (25-36)

You should always calculate your expected loss and how long you can play on a given bankroll before playing any game, but with roulette it's especially important. Making a bet is easy - you just place your chip(s) on the number(s), color, or sets you want to bet on. We've added blue circled letters to the diagram to point out how to make the not-so-obvious bets (the sets of 2-6 numbers) In most games players can continue making bets even while the ball is still spinning. Don't reach for your winnings until the dealer removes the marker, or the dealer will scold you. Roulette chips can in fact be any denomination - $1, $5, $25, etc. When you buy in, tell the dealer what denomination you want. Remember that you can bet inside or outside if you like; there's no requirement to bet both on a given spin. In this way, Roulette is more like slots - one single bet can win a lot. You can certainly switch to another number if you want, but that won't improve or worsen your chances. It's more important to know what the house edge is, than how to calculate it, but here's a quick analysis in case you're interested. if you win, the casino doesn't pay you 37 to 1, they pay you less - 35 to 1. The European wheel has a lower house edge (2.63%) because it has only 37 slots instead of 38 (no 00) If you play Roulette, the most important thing is to find a casino that offers the European wheel (which is called "Single 0" Roulette) Atlantic City has a special rule which reduces the house edge to 2.7% on even money bets (Red/Black, Odd/Even, 1-18/19-36): If 0 or 00 comes up on on even money bet, you lose only half your bet. European games have an option called en prison which reduces the house edge to 1.35%, but it's generally not available in the U.S., even in casinos that use the European wheel. If you win the second spin, your bet is "released from prison" and you get it back.
