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 2by2, you pick 2 numbers from 1–26 (a pool of 26 numbers):

C(26, 2) = 26! / (2! × 24!) = 325 combinations

Then you also pick 2 Whites numbers from 1–26 (a separate pool of 26 numbers):

C(26, 2) = 325 combinations

Since the two draws are independent, multiply them together:

325 × 325 = 105,625 total combinations

Each ticket covers exactly one combination, so your jackpot odds are 1 in 105,625 — which matches the official published odds.

Frequently asked questions

What are the odds of winning the 2by2 jackpot?
The jackpot odds for 2by2 depend on the prize pool and draw rules. See the full prize table above for the exact figures.
How are 2by2 odds calculated?
2by2 odds are calculated using combinatorics — specifically the combination formula C(n,r) = n! / (r! × (n-r)!). You pick 2 numbers from 1–26, giving C(26,2) = 325 combinations, multiplied by C(26,2) = 325 for the Whites ball. The total is 105,625 possible outcomes.
Does buying more 2by2 tickets improve my odds?
Yes — each additional ticket gives you one extra combination. If the jackpot odds are 1 in N and you buy 10 tickets, your odds become roughly 10 in N, or 1 in N/10. That said, even 10 tickets still leaves you with an astronomically small chance of winning the jackpot.
What are the best numbers to pick for 2by2?
There are no "best" numbers. Every combination has an identical probability of being drawn. Quick picks (random numbers) are statistically equivalent to any hand-picked combination. This generator uses cryptographically strong randomness so your picks are as random as possible.
What is the overall chance of winning any prize in 2by2?
The overall odds of winning any prize depend on the number of prize tiers. See the full prize table for details.
