How it’s calculated

Chance = 1 ÷ decimal odds = 1 ÷ 2.50 = 40.0%

Return = stake × decimal odds = $10.00 × 2.50 = $25.00

American: +a means $100 wins $a. Fractional a/b: $b wins $a.

PROLINE tickets

1 in 8

How the provincial lottery sports game works and what a ticket pays. If each of three picks has a 50.0% chance, the chance all three win is 1 in 8.

Hockey bets

24.8%

Moneyline, 60-minute line, puck line and totals. About 24.8% of NHL games go past regulation. That changes which bets win.

Odds converter

+150 → 2.50 → 40.0% chance

Turn American, decimal or fractional odds into each other and into an implied chance.

Margin and no-vig

−110 / −110

At −110 on both sides, each side implies 52.4%. The two add up to more than the whole. That extra is the book's margin.

Parlay payout

Price × price × price

Multiply the decimal prices of all legs. Every leg must win, and each leg adds the book's margin.

Rules by province

18+ / 19+
