How the no-repeat number draw works
- Set the range. It starts at 1 to 75, the numbers on a US bingo card.
- Press Draw for each number. Every number drawn is removed from the pool.
- The list shows every number drawn so far, in order, and the count shows how many are left. Press Start over for a new game.
Uses for a no-repeat number generator
- Bingo: call 1 to 75 for US bingo or 1 to 90 for UK bingo.
- Raffles: draw ticket numbers for first, second and third prize.
- Classrooms: call student numbers so nobody is picked twice.
- Tasks and turns: number the tasks and draw the order to do them.
Does the draw remember my numbers?
Yes. The drawn numbers are saved in your browser, so a refresh doesn't lose the game. Use Clear or Start over to reset. To pick several different numbers in one go instead, use the main random number generator.
Is it really random?
Yes. Every result comes from your browser's cryptographic random number generator, crypto.getRandomValues, the same source used for security keys. Nothing is decided in advance and nothing is stored on our server. See the live fairness test.
