Formula
A reverse bet is two if-bets in opposite orders. Each if-bet places a second wager only if the first wins.
Both win: 2 × ((O₁ − 1) + (O₂ − 1)) × stake
Selection 1 wins, 2 loses: (O₁ − 3) × stake
Selection 2 wins, 1 loses: (O₂ − 3) × stake
Both lose: −2 × stake
Total exposure = 2 × unit stake.
Frequently Asked Questions
What's a reverse bet?
A reverse bet (a.k.a. an if-bet reverse) is two conditional bets fired in opposite orders. Your first selection wins and your unit stake rolls onto the second — and the same logic runs the other way too. Total stake comes to 2× unit stake.
Reverse vs parlay — how do they split?
A parlay needs both selections to win for any payout at all. A reverse still pays when only one wins (at a loss, since you’re risking the second leg). Reverses hand you partial cover in exchange for less upside than a parlay.
When does a reverse make sense?
When you’ve got two confident picks but want to soften the blow if one falls. They’re a staple in US sports betting where parlay-style products are restricted. The math usually edges slightly toward straight singles unless one pick carries very specific risk-management value.
If-bet vs reverse — what separates them?
An if-bet runs one way: A → B, where B only fires if A wins. A reverse is two if-bets pointing opposite ways: A → B AND B → A. The reverse covers more outcomes but doubles the stake.
