United States (multi-state)
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 5 numbers from 70 plus 1 from a separate pool of 24. The number of possible combinations is:
C(70, 5) = 12,103,014 × C(24, 1) = 290,472,336

"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 23.07
Sum of all division probabilities — usually the number the ads quote.
Odds of the top prize
1 in 290,472,336
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 28.1 coin flips in a row correctly (228.1 ≈ 290,472,336). If you bought one line every draw, at two draws a week you would expect one top-prize win roughly every 2,793,003 years.
