European roulette uses a single-zero wheel with 37 pockets (0–36). That lone green pocket shapes every bet you make.
The table separates inside number bets from outside group bets. Same spin, different risk profiles.
Single zero: One green pocket; fewer ways for the house to win than double-zero games.
Number order: A carefully balanced sequence to spread red/black and high/low around the rim.
Inside vs outside: Inside pays more but hits less; outside pays less but lands more often.
Compared with American roulette, the European layout trims the house edge and keeps decisions straightforward without dulling the drama.
Odds, House Edge, and Payouts
The math that matters
With 37 pockets, the baseline house edge is 2.70%. That’s the fraction of each unit the casino expects to keep over time.
Straight up (1 number): 35:1; chance about 1 in 37.
Split (2 numbers): 17:1.
Street (3 numbers): 11:1.
Corner (4 numbers): 8:1.
Line (6 numbers): 5:1.
Dozens/Columns: 2:1.
Even-money (Red/Black, Odd/Even, Low/High): 1:1.
If a table offers la partage or en prison on even-money bets, a zero halves your loss (or parks the stake for one more spin). The effective edge drops to about 1.35% for those wagers-an elegant perk worth seeking.
