Read the payout correctly
Payout ratios show profit only. The winning stake is also returned: a $1 straight win returns $36 total. With combined bets, subtract every stake first; several wins can settle on one spin.
Zero & French rules
Standard outside bets lose on 0 or 00. La Partage returns half only on eligible even-money bets. En Prison rules vary by table; read the layout rules before betting.
French call bets
- Voisins 17 pockets / 9 chips
- Tiers 12 pockets / 6 chips
- Orphelins 8 pockets / 5 chips
- Jeu zéro 7 pockets / 4 chips
A call combines bets across a wheel sector. Net returns vary by winning pocket; there is no special edge.
