Tambola number generator
Host tambola — also called housie — without a number bag. The caller shuffles 1 to 90 at the start of the game and reveals one number at a time, so nothing repeats and everyone can follow along on the board.
Hand out tickets. Use printed or app tickets with numbers from 1 to 90.
Call numbers. Open Tambola caller and press CALL NEXT, or turn on auto-call. Cast your screen to a TV for a big room.
Check claims. When someone claims Early Five, a line, or Full House, check their ticket against the lit numbers on the board.

Questions
About tambola calling and random numbers.
How do I use this as a tambola (housie) number generator?
Switch to Tambola caller. The numbers 1 to 90 are shuffled when the game starts, and each press of CALL NEXT (or the Space bar) reveals one number — never a repeat. Called numbers light up on the board, and you can turn on auto-call and read-aloud for hosting.
Can I play tambola with numbers 1 to 100?
Yes. Choose the 1–100 board in Tambola caller. Standard tambola tickets use 1 to 90, so use 1–100 only if your tickets or game variant need it.
What happens if I refresh the page during a tambola game?
Your game is saved in your browser, so the board and called numbers are still there after a refresh. Press New game when you want to start over.
Are the numbers truly random?
Yes. Numbers come from your browser’s cryptographic random number generator (the Web Crypto API) with rejection sampling, so every number in your range is equally likely.
How do I get random numbers without repeats?
Leave “No repeats” turned on. You can pick up to 500 unique numbers at once, as long as your range has enough numbers in it.
Can I use negative numbers or big ranges?
Yes. Ranges can go from −1,000,000,000 to 1,000,000,000, including negative numbers.
Can I copy the results?
Yes. When you generate more than one number, press Copy to put them on your clipboard as a comma-separated list, or Sort to put them in order first.
