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 7 numbers from 44. The number of possible combinations is:
C(44, 7) = 38,320,568
After the 7 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 | 7 main | 1 | 1 in 38,320,568 | 2.610e-8 | $20,000 a month for 20 years (up to 4 winners per draw) | 1 in 38,320,568 |
| Division 2 | 6 main + ≥1 supps | 14 | 1 in 2,737,183 | 3.653e-7 | $5,000 a month for a year | — |

"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 50.08
Sum of all division probabilities — usually the number the ads quote.
Odds of the top prize
1 in 38,320,568
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 25.2 coin flips in a row correctly (225.2 ≈ 38,320,568). If you bought one line every draw, at two draws a week you would expect one top-prize win roughly every 368,467 years.
