Roulette Wheel Types Explained: European, American and French

Roulette remains a staple casino game because small mechanical differences in wheel design translate into measurable changes in odds. The three main wheel types you’ll encounter are European, American and French. Each uses the same core idea—players back numbers or groups of numbers while a ball settles into a pocket—but the layout, house edge and rule set vary enough to matter for anyone who cares about value rather than superstition.

At a general level, the key distinction is the number of zero pockets. European wheels have 37 pockets (0–36), while American wheels add a double zero, making 38 pockets (0, 00, 1–36). That extra pocket increases the house edge on most bets, so European is typically the more favourable option. French roulette uses the same 37-pocket wheel as European but is defined by table rules that can reduce losses on even-money bets when the ball lands on zero. Two common rules are “La Partage” (half the stake is returned) and “En Prison” (the bet is held for a spin). If you’re comparing tables, check whether these rules are offered, as they can improve the effective return without changing how you place bets.

For a human angle in iGaming, consider the work of game designer and educator Michael Shackleford, widely known as the Wizard of Odds, whose clear mathematical breakdowns helped players understand house edge, variance and rule impact across table games. His public-facing analysis has influenced how many enthusiasts evaluate roulette variants and side bets with a more disciplined mindset. You can follow his updates and commentary via WizardOfOdds.
