What number range does a standard BINGO card use?

A standard 75-ball BINGO card uses five columns labeled B, I, N, G, and O. B contains numbers 1–15, I contains 16–30, N contains 31–45 (with a FREE center square), G contains 46–60, and O contains 61–75.

What is the FREE space?

The center square (N3) is a free space - it counts as marked from the start and can contribute to any winning line that passes through it.

Mark off any complete row, column, or diagonal (including the two main diagonals). When a line is complete, a BINGO! banner is shown.

Can I generate a new card?

Yes. Click "New Card" at any time to generate a fresh random card and reset all marks.

Are the numbers truly random?

Yes. The card is generated using your browser's Web Crypto API for unbiased random selection.

Standard BINGO rules

A standard BINGO card uses a 75-ball format with five columns: B (1–15), I (16–30), N (31–45), G (46–60), and O (61–75). The center square is a FREE space that counts as already marked. Each column contains 5 unique numbers drawn from its range.

Winning patterns

This tool recognizes the three classic patterns: a complete horizontal row, a complete vertical column, or a complete diagonal (top-left to bottom-right, or top-right to bottom-left). When a winning line is completed, the matching cells turn gold and a BINGO! banner is shown.

Custom word BINGO

Traditional BINGO uses numbers, but the game is also a popular educational tool. Teachers use vocabulary BINGO (words instead of numbers), math-facts BINGO (answers to arithmetic problems), and science BINGO (element names, biological terms) to make review sessions engaging. Each player gets a different card arrangement so multiple winners are uncommon.

Probability of BINGO

In a standard 75-ball game with one card, the probability of BINGO by ball n grows slowly at first, then accelerates. On average, the first BINGO occurs around ball 41–43 in a room with a single card. With many players and cards, someone wins much sooner - typically around ball 30–35 in a large hall. The math involves hypergeometric distributions across all possible winning lines, which is why BINGO is a common topic in probability courses.
