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 (also called an if-bet reverse) is two conditional bets placed in opposite orders. If your first selection wins, your unit stake rolls to the second selection — and the same logic applies in reverse. Total stake equals 2× unit stake.
A parlay requires both selections to win for any payout. A reverse pays even when only one wins (though at a loss because you risk the second leg). Reverses give partial protection at the cost of lower upside than parlays.
When should I use a reverse bet?
Reverses are useful when you have two confident picks but want to limit downside if one loses. They’re popular in US sports betting where parlay-like products are restricted. The math usually slightly favours straight singles unless one selection has very specific risk-management value.
What's the difference between an if-bet and a reverse?
An if-bet is one-directional: A → B (B only triggers if A wins). A reverse is two if-bets in opposite directions: A → B AND B → A. Reverse covers more outcomes but doubles the stake.
