Oz Lotto Number Generator

This Oz Lotto number generator picks seven numbers from 1 to 47 per line, the way the Tuesday game is played. Generate one line or up to 20, keep a lucky number on every line, and copy them or print them before you buy. It’s free and there’s nothing to sign up for.

Oz Lotto number generator: odds of all seven

There are 62,891,499 ways to choose seven numbers from 47, so that’s the chance a single line wins Division 1. It’s far longer than a six-number game. Each extra number on the line multiplies the possibilities.

The lower divisions are a lot more reachable. Oz Lotto also draws supplementary numbers, which count towards some of the smaller prizes, so a line with three winning numbers and a supplementary can still pay.

Systems vs single lines

A system entry covers more numbers in one go: eight numbers instead of seven covers all eight seven-number lines inside it. It costs the same as playing those lines separately, so it doesn’t improve the odds per dollar. It just makes sure your lines share numbers in an organised way.

If you’d rather go the other way and spread your lines out, tick “No two lines share more than two numbers” and the generator keeps them apart.

The numbers come from your browser’s built-in secure random generator, the same kind used for encryption. Every combination is exactly as likely as every other, so a generated line is no better or worse than one you choose yourself. What it does do is stop you picking the same birthdays as thousands of other players.

Playing more than one game? The lottery number generator covers eleven lotteries on one page, and the lottery odds calculator works out the chance of every prize tier.

Seven numbers from 47 is a very long shot. Treat it as a bit of fun. BeGambleAware.org is free and confidential if it stops being fun.
