When playing roulette you don't have to play the single numbers and hope for a big 35 to 1 hit. You can make a center bet in a block of four number at 8 to 1 odds. You can also divide your bet in the center to two number and get a 17 to 1 pay out. The total win with these types of bets is not as high as a single number, however your odds are greatly improved by betting multiple number in lieu of just a single spot.
