the.com/roulette wheel

means A spinning disk with numbered pockets that a ball bounces around before settling, used to determine winning bets in the casino game of roulette.

from From French roulette, 'little wheel,' a diminutive of rouelle, itself from Latin rota, 'wheel' — the same root that gives us 'rotate' and 'roll.' The game took shape in France, with the word first attached to the gambling device around the 1700s; the now-iconic addition of a zero (and later double-zero) pocket, which tilts the odds toward the house, came as the wheel's design was refined over that century.
