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
Define a reverse bet.
A reverse (an if-bet reverse) is two conditional bets run in opposite orders. Win the first selection and your unit stake rolls to the second, and the same applies in reverse. Total stake is 2× unit stake.
How does a reverse differ from a parlay?
A parlay needs both selections to win for any payout. A reverse still pays when only one wins (at a loss, since you risk the second leg). Reverses give partial cover, trading off the higher upside of parlays.
When does a reverse bet make sense?
Use one when you hold two confident picks but want to cap the downside if one loses. They’re common in US sports betting where parlay-style products are restricted. The math usually slightly favours straight singles unless a selection carries specific risk-management value.
How does an if-bet differ from a reverse?
An if-bet runs one way: A → B (B fires only if A wins). A reverse is two if-bets in both directions: A → B AND B → A. It covers more outcomes but doubles the stake.
