How the street bet works
A street covers 3 numbers in one row of the layout. Example: 1-2-3. Pays 11:1. Hit probability: European 3/37 = 8.11%, American 3/38 = 7.89%.
Net per win: +11 units. Net per loss: −1 unit. Expected value: −2.70% of stake on European.
Strategy applications
Flat street betting is a moderate-variance inside bet. Used by sector strategies that target specific physical wheel locations.
Combined street bets (multiple streets in one spin) increase hit rate proportionally and decrease net per win.
Three streets covering 9 numbers in adjacent rows: 24.32% hit rate, net per hit on the winning street = 11 − 2 = +9 units.
Variance
Per-spin SD on a $10 street: ~$30. Lower than single-number (~$58), higher than six-line (~$23).
Practical: long flat sections punctuated by 11:1 jumps. Less dramatic than single-number but still spiky.
Test results
