Bingo caller and printable bingo card generator
Free 49-number bingo caller for handwritten 7×7 cards. Host a 3D draw without repeats and print blank cards. Advanced settings generate 2–30 random cards with automatic verification.
Rules and fairness
- Players fill their own cards / Computer-generated cards: Draw a 7×7 grid on scrap or plain paper for each player. Printing is optional. Write each number 1–49 once, in any order. No repeats, omissions or free centre. Wait until everyone has finished. Do not change cards after drawing starts. Advanced settings: Prefer not to fill cards by hand? Generate 2–30 random cards to print, with automatic verification. 1–49 · 7×7 · no free square. Rows, columns and both full diagonals count. Two cards per A4 page, suitable for black-and-white printing. Print copies of blank cards for handwriting. Generated cards print without marks; keep the session after printing.
- Draw next ball: Both modes use Web Crypto to draw uniformly from remaining numbers without replacement, before animation. Handwritten cards are checked by the host; their layouts and champions are not tracked. Advanced generation uses Fisher–Yates permutations of 1–49, rejecting identical cards. Skipping never redraws.
- Check a bingo: When someone calls bingo, the host checks their paper against the called numbers. Handwritten cards have no automatic champion detection. Computer-generated cards: Match the session ID on the paper, then enter its card number. Only revealed numbers count. All cards qualifying on the earliest draw share the title, regardless of who calls or checks first. Continue drawing for other players.

Key features
- Free 49-number bingo caller for handwritten 7×7 cards. Host a 3D draw without repeats and print blank cards. Advanced settings generate 2–30 random cards with automatic verification.
- After k draws, each remaining number has probability 1/(49−k) on the next draw. Fixed cards are not guaranteed equal winning chances; there is no catch-up adjustment.

Randomness and privacy

Both modes use Web Crypto to draw uniformly from remaining numbers without replacement, before animation. Handwritten cards are checked by the host; their layouts and champions are not tracked. Advanced generation uses Fisher–Yates permutations of 1–49, rejecting identical cards. Skipping never redraws.
