Bingo Card Generator

How to Make Bingo Cards

Bingo cards have 5 rows and 5 columns. Each column corresponds to one of the letters B, I, N, G and O. This generator randomly places numbers into the 5 columns. The center spot is usually "free" which means it always counts as a covered spot.

Which Numbers Go in Which Column on a Bingo Card?

Bingo card columns contain 5 numbers each, from 1 to 75. Except for column N which has 4 numbers and a "free" space. For the five columns B, I, N, G, and O, this calculator picks numbers at random from these number ranges:

• B - number range 1-15, pick 5 numbers
• I - number range 16-30, pick 5 numbers
• N - number range 31-45, pick 4 numbers, center space is free
• G - number range 46-60, pick 5 numbers
• O - number range 61-75, pick 5 numbers

Bingo Cards, Probability and Randomness

Bingo cards are generated by random selection of numbers. There are 5.5x10²⁶ possible number combinations and therefore, as many possible playing cards. So the chances of this calculator generating duplicate cards is very, very slim. You can compare cards you will use for a Bingo game to confirm that no two cards are the same.

This Bingo card generator is a pseudo-random number generator (PRNG) that chooses required numbers from the ranges below to create cards.
