🎯 European vs American: The $1,000 Difference
The single biggest mistake recreational roulette players make is playing the American (double zero) wheel when a European table is available.
On a $10 bet over 1,000 spins:
- European (2.70% edge): Expected loss = $270
- American (5.26% edge): Expected loss = $526
That is a $256 difference just from choosing the wrong table. The house edge on American roulette is nearly double that of European roulette — all because of one extra green pocket (00).
📊 All Roulette Bets Ranked by House Edge
Here is the truth most casino sites won't tell you: every single bet on a standard roulette wheel has the same house edge.
Whether you bet Red/Black (1:1) or a Straight Up number (35:1), the casino's mathematical advantage is identical:
- European: 2.70% on ALL bets
- American: 5.26% on ALL bets (except the 5-number bet at 7.89%)
The only exception is the La Partage / En Prison rule on some European tables, which drops the edge to 1.35% on even-money bets. If you play roulette, finding a La Partage table is the single most +EV decision you can make.
