The first difference is the card used for playing. American bingo cards have five columns and rows, all containing numbers except for the middle box. Every column is named after a letter in the word “bingo” and has a range of 25 numbers.
Hence, column B can have numbers 1 to 25, column I from 26 to 50, and so forth. In UK bingo, cards follow the 9 columns by 3 rows pattern. A column can have 10 numbers, but each row can only have 5 numbers. This means that there will be boxes that do not have any numbers at all. The cards also reveal another difference: American bingo has 75 numbers while its UK counterpart has 90.
