FAQ
What is a parlay?
Multiple bets combined into one ticket. All legs must win for the parlay to pay. Combined odds = product of individual odds.
Are parlays good value?
Generally no. Bookmaker margin compounds across legs. A 3-leg parlay at standard 5% margin per leg loses ~14% of fair value.
What is the maximum number of legs?
Varies by sportsbook. Stake supports parlays of 2–12+ legs. More legs = exponentially lower probability of cashing.
Can same-game parlays improve odds?
They appear better but bookmakers correlate the legs to maintain margin. Read the SGP terms carefully.
