The purpose of this is to preserve the randomness of the game and prevent sharp-eyed players from predicting the outcomes. If you take some time to scrutinize how these numbers are ordered around the wheelhead, you will discern they are placed in such a way so that red, black, odd, even, high, and low numbers are evenly dispersed. There 18 red/odd/low numbers and 18 black/even/high numbers as is the case on all roulette wheels. The sequencing of the numbers on French wheels coincides with that on European ones. The numbers on the wheel are dispersed and do not appear in the same order as they do on the betting layout. French roulette uses a wheel with a total of 37 divisions that contain numbers 1 to 36, with 18 black and 18 red pockets that alternate along with a single-zero pocket colored in green.
