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 Lotto NZ, you pick 6 numbers from 1–40 (a pool of 40 numbers):
Each ticket covers exactly one combination, so your jackpot odds are 1 in 3,838,380 — which matches the official published odds of 1 in 3,838,380.
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 3,838,380:
