Low bet / Manque: numbers 1 - 18 (Manque is French for "failed" and is used because the ball has failed to pass 18) High bet / Passe: numbers 19 - 36 (Passe is so named because it has "passed" the centrepoint)

A wager that one of the high numbers (19-36) will win. Also known as 'Passe' in French Roulette.
