Saturday Lotto odds for every match

Eight balls come from one barrel: six winning numbers, then two supplementaries. A supplementary only helps on the numbers you missed.

Match Odds per line
6 1 in 8,145,060
5 + supplementary 1 in 678,755
5 1 in 36,689
4 + supplementary 1 in 7,240
4 1 in 815
3 + supplementary 1 in 297
3 1 in 52.4
2 + supplementary 1 in 33.5
2 1 in 8.2

For m matches: C(6, m) × C(39, 6 − m) ÷ C(45, 6). The supplementary split checks whether any of your other numbers is one of the two.

Why it’s the best-odds lotto in Australia

Saturday Lotto has the smallest number pool of the national games, so it’s the easiest Division 1 to hit: about 7.7 times easier than Oz Lotto and 16.5 times easier than Powerball. The jackpot is smaller as a result, typically a few million rather than tens of millions, and more often shared.

Playing 12 games every Saturday for 10 years gives about a 1 in 1,300 shot at Division 1. Change the numbers in the calculator to see your own.
