Tool · Parlays
Most parlays are -EV. Some aren't.
Most parlays lose to the book's margin. Whet's parlay board shows which book prices your whole ticket, and what it pays, before you place it.
The parlay board
- Every game
- Every game in every league on the board for the next three days, and every bet in the game you pick.
- Your legs
- Tap any + to start a parlay. Your legs land in the slip.
- The book
- The slip shows which book prices every leg and what the ticket pays there. Then place it at your book.
Compound vig.
Each leg of a parlay carries the book's margin. A single bet at -110 has ~4.5% vig. A 3-leg parlay at -110 per leg compounds that: the price implies a better chance of cashing all three than you have, and that gap is the vig, taken three times over. Books love parlays because the structure favors the house.
Holding a slip and want the number? The parlay calculator multiplies the legs and, with the other side of each market, shows the fair payout and what the book keeps.
Common questions.
- Can a parlay ever be +EV?
- Yes, when every leg is priced better than its real chance. It is uncommon, because the book's margin compounds with every leg you add.
- How many legs should a parlay have?
- Fewer than you want it to. Each leg multiplies both the book's margin and the size of the swings.
- Which plan includes parlays?
- Whet, at $24.99 a month.
