90-ball bingo
90-ball bingo is the bingo format played with balls numbered 1 to 90 and tickets laid out as a grid of three rows and nine columns, each ticket carrying 15 numbers. It is the standard game in Irish and British halls and online rooms, and every game is played for three prizes in turn: one line, two lines and a full house. Tickets are usually sold in strips of six, which between them hold every number once.
How a 90-ball ticket is built
Each row holds five numbers and four blanks, so 27 squares carry 15 numbers. The numbers sort by column, lowest on the left and up to 90 on the right, though operators split the ranges differently: some print 1–9 in the first column, others 1–10.
Six tickets of 15 make 90, which is why a strip covers the whole game.
90-ball against other bingo formats
The format most often confused with it is 75-ball, the North American game. The rows below come from published operator rules and game guides.

What a full strip does not guarantee
A full strip means every number called lands somewhere on your tickets, and players often read that as a better chance of winning than the price alone explains.
It is not. A prize still needs the right numbers on a single ticket, and six tickets give six chances whether they come as a strip or as loose tickets. What the strip changes is the pace of marking, not the odds per ticket, which depend only on how many tickets are in play across the whole room.
Coverage is not an edge.
