Combined odds and potential payout, like all of them. Plus what the others hide: the bookmaker margin compounds with every leg, and here you watch it grow.
This is the expected value of the slip, and it does not depend on which odds you pick: every leg multiplies what you keep by 0.95. That is why bookmakers promote parlays, not singles.
At a typical 5 % margin per leg. Going from one leg to five is not linear: it multiplies by more than four.
| Legs | House take |
|---|---|
| 1 | 5.0 % |
| 2 | 9.8 % |
| 3 | 14.3 % |
| 4 | 18.5 % |
| 5 | 22.6 % |
| 6 | 26.5 % |
| 8 | 33.7 % |
| 10 | 40.1 % |

By multiplying the odds of every leg. A parlay at 1.85, 1.70 and 2.10 pays 1.85 × 1.70 × 2.10 = 6.60. Every leg must win: if one loses, the whole slip loses.
Because their margin multiplies with every leg. If the house keeps 5% on each price, a five-leg parlay hands it 22.6% of the slip value — four times a single. Parlay boosts exist to push you toward exactly the product where your bets leave the most margin.
At a 5% margin per leg, the expectation is losing 5% on a single, 9.8% on a double, 14.3% on a treble and 22.6% on a five-leg — whatever the odds. The formula is 1-(0.95 to the power of the number of legs).
Mathematically they only pay off if every leg has value on its own (odds above the true probability), because then the value compounds too. That is exactly the craft this platform verifies: finding value prices, pick by pick, with a sealed track record. If any leg lacks value, adding it only increases the house take.
