Generate lottery-style number combinations for any format. Set the number range — for example 1 to 33 — how many numbers each line should contain, and how many lines (tickets) you want. Within each line the numbers are drawn without replacement, so a single line never repeats a number, just like a real draw. Optionally sort each line in ascending order, and copy every line at once for easy pasting.
Numbers come from crypto.getRandomValues, the browser's cryptographically secure random source, combined with rejection sampling that discards values which would introduce a modulo bias, so each number in the range is exactly equally likely. Everything runs locally in your browser and nothing is sent to any server. This is a random-number toy for fun and quick pick ideas, not a prediction or a guarantee of winning.
