Decimal odds are your stake multiplier: at 2.50, a $10 bet returns $25 in total if it wins, or $15 profit. It's the format all three of our operators display.
Divide 1 by the odds to get the implied probability: 1 ÷ 2.50 = 40%. The lower the odds, the more likely the bookmaker thinks the outcome is.
On September 24, 2026, a Japan–Uruguay friendly was listed at Ice with these 1X2 odds: 1.74 (Japan), 3.70 (draw) and 4.40 (Uruguay).
| Japan · 1.74 | 1 ÷ 1.74 = 57.5% |
|---|---|
| Draw · 3.70 | 1 ÷ 3.70 = 27.0% |
| Uruguay · 4.40 | 1 ÷ 4.40 = 22.7% |
| Total | 107.2% |
The three outcomes add up to more than 100%: the extra, about 7%, is the bookmaker's margin. Comparing odds for the same match across operators means looking for the thinnest margin.
