La Primitiva odds — every division, derived

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.

The combinatorics

A standard entry picks 6 numbers from 49 plus 1 from a separate pool of 10. The number of possible combinations is:

C(49, 6) = 13,983,816 × C(10, 1) = 139,838,160

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 53.66

Sum of all division probabilities — usually the number the ads quote.

Odds of the top prize

1 in 139,838,160

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 27.1 coin flips in a row correctly (227.1 139,838,160). If you bought one line every draw, at two draws a week you would expect one top-prize win roughly every 1,344,598 years.
