What are the actual top-prize odds?

1 in 62,891,499 — the number of ways to choose 7 numbers from 47. That is roughly six times longer than Irish Lotto's 1-in-10,737,573, which only asks for 6 from the same 47 — one extra number to match makes a large difference to the odds.

Oz Lotto-Style Number Generator

Generates 7 random main numbers between 1 and 47, matching the Australian Oz Lotto draw format. The three supplementary numbers are drawn by the operator from the balls left, so they are not part of a line.

Every valid number combination has exactly the same probability. This tool cannot improve your odds, and past draws never make any number more or less “due”.

What this generator does

Generates a seven-number Oz Lotto line. Seven main numbers rather than the usual six is what distinguishes Oz Lotto, and it is why filling a slip by hand takes longer and why the top-prize odds are considerably longer than a six-number game.

Worked examples

A full line: Seven main numbers from 1–47 — one more number to pick than a typical six-from-47 format.
Including a number you want to keep: Lock in a number you always play and the remaining six main numbers are drawn around it, rather than it being left to chance alongside the rest.

Common use cases

Generating your own Oz Lotto-style numbers
Comparing self-picked numbers against a quick-pick

Limitations and good to know

Seven numbers from 1 to 47, which is why an Oz Lotto line is longer than most.
Seven numbers from 47 makes the top-prize odds considerably longer than a six-number game, which is worth knowing before comparing jackpots between draws. No method of choosing the seven improves them.
