Random Number Bingo Card Generator

Used by developers, writers, and creators worldwide.

A random number bingo card generator saves you from hand-writing grids or wrestling with spreadsheet formulas before game night. Each card is a 5×5 layout with 24 unique numbers and a free centre square — the standard 75-ball format. Set the highest number to 75 for classic play, lower it to 30 for a faster kids' round, or push it past 75 to stretch a fundraiser event. Every card is independently shuffled, so duplicates across a batch of 20 or 30 cards are vanishingly rare. Configure two settings, click generate, and copy the output straight into a document for printing.

  • →Set the maximum to 30 and generate 10 cards for a fast-paced children's game that wraps up in under 15 minutes.
  • →Pair the output with a random number generator set to the same maximum — bookmark both tabs before your event starts.
  • →If printing, use a monospace or table font when pasting into a document so columns stay aligned without extra formatting work.
  • →For virtual bingo over video call, share each card image individually with players in advance so no one sees another's card.
  • →Regenerate cards completely if you reuse the same game format the following week — players memorise patterns on familiar cards over repeated sessions.

FAQ

how many numbers are on a standard bingo card

A standard 75-ball bingo card has 24 numbers in a 5×5 grid plus a free space in the centre, totalling 25 squares. This generator follows that layout exactly. If you want 90-ball play, set the highest number to 90 — the grid stays 5×5 rather than the traditional UK 9×3, but the number pool matches.

are all the generated bingo cards guaranteed to be unique

Each card is independently shuffled from the number pool, and the number of possible 5×5 bingo arrangements runs into the trillions, so duplicates in any realistic group are extremely unlikely. For large events over 50 players, regenerate the batch once and do a quick visual spot-check for extra confidence.

what maximum number should I use for kids or shorter games

Set the highest number to 25 or 30 — a smaller range means called numbers hit cards faster, rounds finish in minutes, and younger players stay engaged. You can also generate fewer cards to keep the caller's pace comfortable. Raising the maximum above 75 does the opposite, stretching play time for fundraisers or longer events.
