How to play
- Choose an operation, a number range, and how many cards to generate.
- Click Generate cards to build a set of bingo cards that are checked for uniqueness against each other.
- Switch to the caller screen and click Call next to read problems aloud; each call is added to the history list.
- Use Print all cards to print a paper copy for every player, or check Card previews to see every grid on screen.
Pick an operation — addition, subtraction, or multiplication — set a number range, and choose how many players need a card. This tool builds a full set of bingo cards where every card is checked against every other card so no two are ever the same, using a fair shuffle to fill each 5x5 grid with distinct answers and an optional free center space. Once the cards are ready, switch to the caller screen to draw problems one at a time; each call is logged in a running history so you can always see what has already been read aloud, and the call list is built to cover every answer used on every card. When the round is over, print the whole set of cards as individual pages. Nothing you type or generate is uploaded anywhere — the whole tool runs in your browser and works without an internet connection.
Frequently asked questions
- How does the tool make sure no two cards are the same?
- Every newly built card's full grid is compared against every card already generated, and any exact duplicate is discarded and rebuilt, so the finished set is guaranteed to contain no two identical cards.
- Will the caller screen ever call a number that isn't on any card?
- No. The call list is built directly from the answers that actually appear on the generated cards, so every call corresponds to at least one card and no card is left waiting on a number that will never be called.
- What happens if I pick too small a number range?
- If the range doesn't contain enough distinct answers to fill a card, the tool shows a clear message asking you to widen the range instead of generating broken or repeated cards.
