Historians have dated both ‘double zero’ and ‘single zero’ roulette back to the late 1700’s and although the popularity of the game has spread worldwide and ebbed and flowed the 18th-century player would have no problem recognizing today’s version of the game. Roulette has changed very little over the past few centuries. These are terms that you’ll hear often in roulette discussions so it’s a good idea to take the time and understand what these terms mean, the differences between the games and the odds on each variation of roulette.
