Every figure on this page is calculated from the game's published rules. The operator's own odds page is linked below as verification — but the working is here, on this page.
A standard entry picks 6 numbers from 45. The number of possible combinations is:
C(45, 6) = 8,145,060
After the 6 winning numbers, 2 supplementary/bonus balls are drawn from the same pool — they create extra divisions but don't change the jackpot odds.
| Division | Match | Winning combinations | Derived odds | Probability | Prize | Operator says |
|---|---|---|---|---|---|---|
| Division 1 | 6 main | 1 | 1 in 8,145,060 | 1.228e-7 | Jackpot pool share | 1 in 8,145,060 |
| Division 2 | 5 main + ≥1 supps | 12 | 1 in 678,755 | 1.473e-6 | Pool share | 1 in 678,755 |
| Division 3 | 5 main + 0 supps | 222 | 1 in 36,689 | 2.726e-5 | Pool share | 1 in 36,689 |
| Division 4 | 4 main | 11,115 | 1 in 733 | 0.1365% | Pool share | 1 in 733 |
| Division 5 | 3 main + ≥1 supps | 27,380 | 1 in 297 | 0.3362% | Pool share | 1 in 297 |
| Division 6 | 1 main + 2 supps or 2 main + 2 supps | 56,610 | 1 in 144 | 0.6950% | Pool share | 1 in 144 |
"Winning combinations" counts how many of the possible outcomes land in that division. "Operator says" is the operator's published figure — shown so you can check us against them (small differences are their rounding).
Odds of winning any prize
1 in 85.43
Sum of all division probabilities — usually the number the ads quote.
Odds of the top prize
1 in 8,145,060
One standard game. Two games doubles it — and it's still tiny.
How long are these odds? Winning the top prize is about as likely as calling 23 coin flips in a row correctly (223 ≈ 8,145,060). If you bought one line every draw, at two draws a week you would expect one top-prize win roughly every 78,318 years.
