How numbers are drawn
Pressing Generate uses your browser's cryptographic random number generator (crypto) to pick 6 unique numbers from 1 to 45 with a uniform, unbiased distribution. Unlike ordinary pseudo-random generators, it's unpredictable and fair, so every number has an equal chance. You can create up to 5 sets at once, and each set shows its sum and odd/even split so you can glance over the combination.
Exclude and fixed numbers
Open the options to enter numbers to exclude and numbers to fix (always include), separated by commas. For example, exclude last week's winning numbers, or fix your birthday numbers and let the rest be random. Fixed numbers can be up to 6; if too many numbers are excluded to form a set of 6, or a number appears in both lists, you'll see a note.
Good to know
Lotto is a fully random draw, so there is no 'lucky' combination and no number pattern that wins more often — auto-picked, hand-picked, or generator numbers all share the same 1-in-8,145,060 odds. This tool just helps you pick fairly at random; it does not guarantee or improve your chances of winning. Please play responsibly. All calculations run only in your browser.
Frequently asked questions
How are the numbers generated?
Your browser's crypto RNG picks 6 unique numbers from 1–45 with a uniform distribution — fully random each time, with no server or algorithmic bias, and nothing is sent to a server.
Can I exclude or force-include specific numbers?
Yes. Excluded numbers never appear; fixed numbers are included in every set (up to 6). The rest of each set is filled at random.
Do generated numbers improve my odds?
No. Every combination has identical odds in a random draw. This tool only helps you pick fairly at random and does not guarantee or increase any chance of winning — play responsibly.
