Red and black togeda dey lose $20 for di zerowheelZeroDi one green pocket wey no even-money, dozen or column bet dey cover; na im be di source of di house edge. Dem also dey call am: single zero, 0.Read di whole tin → and notin for di rest: −$20/37, 2.70% of $20.
Red dey come out 18 times for 37: di $10 dey win $10 and di $1 on 17 dey lose, +$9. Di 17 dey come out once: di red bet dey lose $10 and di $1 dey win $35, +$25. Di oda 17 black numbers and di zero, 18 pocketsequipmentPocketOne of di 37 small boxes wey get number for di rotor. Dem also dey call am: slot, cup.Read di whole tin → in all: both bets dey lose, −$11.
