What is the highest number on a roulette wheel?

Although the total number of slots differs between American roulette, with 37 and 38 respectively, this is only due to the extra double zero in the American version. Otherwise, both wheels have 36 numbered pockets, alternating in black and red, ranging from 1 to 36, with green pockets for the zeros. Therefore, the highest number on a roulette wheel is 36, which is painted red in both variations.
