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 is a reverse bet?
A reverse bet (a.k.a. an if-bet reverse) is two conditional bets set up in opposite orders. Win the first selection and your unit stake rolls onto the second — and the same logic runs the other way too. Total stake comes to 2× your unit stake.
How is a reverse different from a parlay?
A parlay needs both selections to win for any payout at all. A reverse still pays when only one lands (at a loss, since you’ve risked the second leg). Reverses hand you partial protection, trading away some of the parlay’s upside.
When should I reach for a reverse bet?
Reverses shine when you’ve got two confident picks but want to soften the blow if one slips. They’re a favorite in US sports betting where parlay-style products are limited. The math usually nudges you toward straight singles unless one selection carries very specific risk-management value.
What sets an if-bet apart from a reverse?
An if-bet runs one way only: A → B (B only fires if A wins). A reverse is two if-bets pointing opposite directions: A → B AND B → A. The reverse covers more outcomes but doubles your stake.
