Directly beneath the numbers are three clean spaces (on some layouts these are marked “2 to 1” and are situated on the players’ facet of the table). On either side of these or alongside one aspect of the columns are rectangular areas marked “1st 12,” “2nd 12,” and “3rd 12” on American-style layouts. On European-style layouts these phrases are “12p” (première), “12m” (milieu), and “12d” (dernière douzaine). Six more areas are marked “red” (rouge), “black” (noir), “even” (pair), “odd” (impair), “1–18” (low, or manque), and “19–36” (high, or passe). The roulette desk is composed of two sections, the wheel itself and the betting structure, higher known as the roulette format. One has a single betting structure with the roulette wheel at one end, and the opposite has two layouts with the wheel within the centre.
