Bingo Caller Sequence Generator

Running a game by hand means drawing numbers without repeating one and then settling the argument when two people shout at the same time. This draws the entire call order in advance — every number in the game exactly once — and then replays it against each card to find the call at which that card actually completed a line, two lines and a full house. Nobody has to take anybody's word for it.

Game

Cards in play

Between 1 and 40.

Seed (optional)

The same seed calls the same game again while the generator is unchanged. Deterministic, not cryptographic.

A game called from a seed is in the address with its settings: the link calls the same game while the generator is unchanged.

The call order and the winning call for every card will appear here.

What this generator does

Shuffles every number in the game into a call order, deals the cards, and then walks the calls one at a time marking each card, recording the call number at which each stage was completed.

How to use this tool

Choose the 90-ball ticket or the 75-ball card.
Set how many cards are in play, one per player.
Add a seed if you want the same game called again later: the calls repeat unless the generator has changed since.
Print the call sheet: the order to read out, the cards, and when each one wins.

Understanding the controls

Game: The 90-ball ticket is three rows of nine with fifteen numbers on it; the 75-ball card is five by five with a free centre square. The pool of numbers follows from the choice.
Cards in play: How many different cards to deal, from one to forty. Every card is checked against the others so no two players hold the same one.
Seed (optional): Type anything to call the same game again from the same words. Deterministic, not cryptographic — leave it empty for a fresh game.

Worked examples

Three 75-ball cards, one real game: With the seed round11: card 3 got the first line at call 33 and two lines at call 44; card 1 followed (calls 39 and 48) and was the first to a full house, at call 72 of the 75. Card 3 finished at call 74, and card 2 was last home at call 75, the very last number in the pool.

Common use cases

Running a charity or community bingo night without a machine
Settling which card genuinely got the line first
Checking a game is winnable before you print the cards
Practising calling before the night itself
Playing a whole game over a video call, where nobody can draw from a bag

How this generator works

The call order is a shuffle of the whole pool, so a repeat is impossible by construction rather than caught by rejection. The winning call is then found by replay: the sequence is walked from the start, each card marked as its numbers come up, and a line recorded at the call that completed it. Every claim on the page is re-derived from the sequence a second time and compared, so a stage cannot be reported one call early or late.

Randomness and fairness

The call order comes from your browser's cryptographic random source unless you give a seed, in which case the same seed reproduces the same game — deterministic, not cryptographic.

Limitations and good to know

The house rules here are one line, two lines and a full house; four corners and pattern games are not scored.
On a 90-ball ticket a line is a row of five numbers, which is how the game is normally played. On a 75-ball card a line is any row, any column or either diagonal, the free centre counting towards the lines through it.
Every card reaches a full house eventually, because the whole pool is called — the interesting number is when.
Forty cards is the limit, which is where distinctness stops being comfortable in the 75-ball game.

Privacy and your data

The game is called in your browser. No cards or call orders are transmitted or stored. A seed of lower-case letters, digits and hyphens goes into the address bar with the game and the number of cards, so that the link calls the same game; any other seed stays out of it.
