How the maths works
Lottery odds come from combinatorics — counting how many ways you can choose a subset of numbers from a pool. The formula is:
C(n, r) = n! / (r! × (n − r)!)
where n = pool size, r = numbers to choose
For Keno NZ, you pick 10 numbers from 1–80 (a pool of 80 numbers):
Each ticket covers exactly one combination, so your jackpot odds are 1 in 1,646,492,110,120 — which matches the official published odds of 1 in 8,911,711.
Does buying more tickets help?
Yes — but the improvement is smaller than you might think. Each ticket adds one independent combination to your entry. With n tickets, your jackpot odds become n in 8,911,711:
