Number caller

Calling bingo for the table? Press Call next and a number is drawn at random from the ones not yet called. Mark the board as you go, or let auto-call do the calling.

Tips

Numbers come from the browser's cryptographic random generator, and each game draws every number exactly once.
Auto-call stops by itself after the last number. Pause keeps the time left until the next call.
The game type, range and called numbers are remembered on this device only, so a refresh does not lose your game.

Questions

Are the calls random and fair?

Yes. Each call picks one number at random from the numbers not yet called, using the browser's cryptographic random generator. Nothing is pre-set or repeated within a game.

Is anything sent anywhere?

No. The called numbers and your settings are kept in this browser on this device. Nothing is sent to Paperoom or any other service.

Does it work offline?

Once Paperoom is installed or the page has been saved for offline use, the number caller runs without a connection.
