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 run in opposite orders. If your first pick wins, your unit stake carries over to the second pick — and the same applies the other way round. Your total stake comes to 2× unit stake.
How is a reverse different from a parlay?
A parlay needs both picks to win before it pays anything. A reverse still pays when only one wins (at a loss, since you risk the second leg). Reverses give you partial protection, with less upside than a parlay.
When should I go for a reverse bet?
Reverses come in handy when you’ve got two confident picks but want to soften the blow if one loses. They’re popular in US betting where parlay-style products are limited. The maths usually leans slightly toward straight singles unless one pick has very specific risk-management value.
What's the difference between an if-bet and a reverse?
An if-bet runs one way: A → B (B only fires if A wins). A reverse is two if-bets in opposite directions: A → B AND B → A. A reverse covers more outcomes but doubles your stake.
