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 39. The number of possible combinations is:
C(39, 6) = 3,262,623
After the 6 winning numbers, 1 supplementary/bonus ball is drawn from the same pool — they create extra divisions but don't change the jackpot odds.

"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 27.83
Sum of all division probabilities — usually the number the ads quote.
Odds of the top prize
1 in 3,262,623
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 21.6 coin flips in a row correctly (221.6 ≈ 3,262,623). If you bought one line every draw, at two draws a week you would expect one top-prize win roughly every 31,371 years.
