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 defines a reverse bet?
A reverse bet (also termed an if-bet reverse) consists of two conditional bets sequenced in opposite orders. When your first selection wins, the unit stake carries forward to the second selection — and the identical logic runs in the reverse direction. Total stake equals 2× the unit stake.
How does a reverse differ from a parlay?
A parlay needs both selections to win before any payout occurs. A reverse still returns when only one selection wins (at a loss, since the second leg is risked). Reverses deliver partial protection at the cost of lower upside relative to parlays.
When is a reverse bet the right choice?
Reverses suit situations where you hold two high-confidence picks but want to contain the downside if one loses. They are common in US sports betting, where parlay-style products face restrictions. Mathematically, straight singles usually hold a slight edge unless one selection carries specific risk-management value.
How does an if-bet differ from a reverse?
An if-bet runs in one direction only: A → B (B fires solely when A wins). A reverse is two if-bets running in opposite directions: A → B AND B → A. The reverse spans more outcomes but doubles the stake.
