La Partage Roulette Rule Explained
La Partage is a French roulette rule that returns half an even-money stake when the ball lands on zero. For Canada players comparing roulette tables at licensed online casinos, the rule matters because it cuts the house edge on qualifying outside bets from 2.70% to 1.35%. It applies to red/black, odd/even, and high/low wagers on single-zero games, not to straight, split, street, corner, or other inside bets. This glossary explains the formula, the difference from En Prison, and the checks players should make under Canadian provincial regulation before choosing a roulette table.
How La Partage Reduces Roulette House Edge
La Partage changes only the zero result, not the wheel odds. On a single-zero roulette wheel with 37 pockets, an even-money bet covers 18 numbers and normally loses when 0 appears. Under La Partage, the dealer or RNG system returns 50% of the stake and collects the other half. That adjustment reduces expected loss from 1 unit per 37 spins to 0.5 units per 37 spins, so the house edge on qualifying wagers is 1.35% instead of 2.70%.
La Partage Compared With Standard Roulette
La Partage should be compared with the wheel type first. American roulette uses 0 and 00, so even-money bets carry a 5.26% house edge because two losing zero outcomes sit on a 38-pocket wheel. Standard European roulette has one zero and a 2.70% edge. French roulette with La Partage keeps the single zero but shares the loss on red/black, odd/even, and 1-18/19-36. En Prison can reach the same 1.35% edge, but it holds the bet for another spin instead of returning half immediately.
