90-Ball Bingo
The traditional UK and European bingo format played on a 9x3 ticket with numbers 1-90, offering three prizes per game: one line, two lines and a full house.
Definition
90-Ball Bingo uses tickets of three rows and nine columns, with each row containing five numbers and four blanks (fifteen numbers per ticket). Numbers from 1 to 90 are drawn one at a time by a random number generator online or a mechanical machine in halls, and players mark matches automatically or by hand. A single game typically pays three prizes of increasing value: completing any one horizontal line, then any two lines, then all fifteen numbers for the 'full house'. Like all bingo, the operator retains a portion of ticket sales as its margin, so the pooled prizes returned to players are less than the total staked, making it entertainment with a built-in negative expected value rather than a way to earn money.
Worked example
A player buys six tickets for a 50p game; numbers are called until someone completes a line, then two lines, and finally the full house, with each prize a fixed or pooled amount announced before the game.
Why it matters
For learners it is the entry point to understanding how bingo prizes are structured and pooled; for professionals it defines a distinct product vertical with its own ticket math, prize splits and session pacing.
