Call bingo numbers for a group without a cage

1–75, shuffled and called one at a time, with the letter columns announced — the caller part of a bingo game, minus the plastic balls.

The job

Someone has to draw and call numbers without repeats, and announce them the way players expect — 'B-7', not just '7'. The caller draws, announces by column letter, and keeps a call history so disputed boards can be checked.

Draw and announce

Tap to draw: the number appears with its column letter (B 1–15, I 16–30, N 31–45, G 46–60, O 61–75). The history grid shows everything called; undo takes back a mistaken draw without burning the number.

Calls copy to clipboard as a text log — handy for settling 'was G-52 called?' afterwards.
75 draws exhausts the game; the tool ends the round rather than repeat a number.

Cards and fairness

Pair it with bingo-card for the players' boards. Draws use a Fisher-Yates shuffle seeded from crypto randomness — the same uniform ordering the card generator uses.
