Bingo is a game of chance in which players purchase cards containing a grid of numbers. As numbers are drawn at random, players mark matching numbers on their cards. The objective is to complete a predefined pattern, typically a straight line, a full house, or another arrangement, to win a prize.

Most forms use a 5-by-5 card with a free space in the center. In the United States, letters B-I-N-G-O designate columns with numbers drawn from specific ranges (B: 1–15, I: 16–30, N: 31–45, G: 46–60, O: 61–75) and a full card is often required for a blackout. In the United Kingdom and many other regions, bingo cards are printed for numbers 1–90 and patterns vary.

The game proceeds with a caller drawing numbers, which are announced to players. Players mark numbers on their cards accordingly. When a player completes the required pattern, they call out the win and claim the prize. In many venues, multiple winners may share a prize, depending on house rules.

Bingo originated from lottery-like games in Europe and developed into a popular form of entertainment and fundraising in the United States during the early 20th century. It gained a charitable and social role in many communities, with halls and clubs hosting games to support organizations.

Today bingo is played in physical halls, as casino games, and online. Online bingo often uses computerized random number generators and can feature various formats, such as speed bingo, fixed patterns, or progressive prizes. Electronic cards and caller software are common in institutional settings.

Regulation and accessibility vary by jurisdiction. Licensing, age limits, and responsible-gambling measures apply in many places. Charitable bingo remains important in some countries, while commercial variants predominate in others.
