Can a previous number be checked?

Yes. Every revealed call remains in the ordered history until the game is reset.

Does switching variant keep the old game?

No. Changing between 75-ball and 90-ball resets the sequence so histories cannot be mixed.

Do my entries leave this device?

No tool value is sent, stored, logged, or placed in the URL. Closing or refreshing the tab clears the current work. Regular site analytics may still load without receiving the values.

What makes the selection random?

The tool uses the browser's Web Crypto getRandomValues source and unbiased integer selection. Filters and constraints change the eligible set, not the chance among remaining valid choices.

Secure browser-local randomizer

75-ball and 90-ball bingo caller

Start a securely shuffled call order, reveal one number at a time, and keep the full history visible for verification. The 75-ball version includes B-I-N-G-O column labels.

Bingo variant

Set the options, then generate a result.

How it works

Choose the 75-ball or 90-ball variant and start a game.
Use the call button with a mouse, touch, Enter, or Space.
Check the current call, history, and remaining count; reset for a new game.

Worked example

In 75-ball bingo, number 31 appears as N-31 because N covers 31–45. In 90-ball bingo the same call is shown as 31.

Limits and checks

Each game is a permutation of 1–75 or 1–90, so a number cannot repeat.
Resetting intentionally discards the current call order and history.
This caller does not generate player cards, verify wins, or replace the host's game rules.

Privacy
