Bingo Card Generator

Standard BINGO Card

A BINGO card is a 5×5 grid with the letters B-I-N-G-O across the top. Each column contains a random selection of numbers from a specific range. The center square is a free space.

Number Ranges by Column

Each column draws 5 unique numbers from its 15-number range (or 4 for N, since the center is free). The total pool is 75 balls.

How to Win

Standard winning patterns include:

• Line: 5 in a row horizontally, vertically, or diagonally
• Blackout: All 25 squares covered
• Four corners: The four corner squares
• Letter patterns: T, L, X, and many more

How many different cards exist

Counting cards where position matters, the total is P(15,5) for four columns and P(15,4) for the N column, which is 360,360⁴ × 32,760, or about 552 septillion. Ignore the ordering within each column and the figure drops to C(15,5)⁴ × C(15,4), roughly 111 quadrillion. Either way, two players getting the same card by accident is not something you need to plan around.

Randomness

Each column is drawn with a Fisher-Yates shuffle, so every legal card is equally likely. Nothing stops two identical cards appearing in the same batch, it is simply far too unlikely to matter.

Printing

Use your browser’s print function (Ctrl+P or Cmd+P) to print the generated cards. Set paper size to Letter or A4 and use portrait orientation for best results. Four cards fit on one portrait page at default scaling.

Customising the header

The header box takes any five-letter word, so a themed night can run on TRIVIA, PARTY, GHOST or the name of whatever you are celebrating. The number ranges do not change, only the letters over the columns, which means a card printed under a custom header still plays against a standard 75-ball caller.

Uses

Bingo turns up at school fundraisers, office parties, retirement homes, holiday events and classrooms. It survives in all of them for the same reason: there is no skill in it, so a table of eight can play across four decades of age difference and nobody is carrying anybody.
