The game is presided over by a caller, whose job it is to call out the numbers and validate winning tickets. They will announce the prize or prizes for each game before starting. The caller wil then usually say "Eyes down" to indicate that he is about to start. They then begin to call numbers as they are randomly selected by an electronic random number generator (RNG).

As each number is called, players check to see if that number appears on their tickets. If it does, they may mark it with a special marker called a “dabber”. When all the numbers required to win a prize have been marked off, the player shouts in order to attract the caller’s attention. There are no formal rules as to what can be shouted, but most players will shout “Yes” or “Bingo”. Some players may also choose to shout “Line” or “House” depending on the prize, whilst others choose to shout “house” for any win (including a line or two lines), players may use any other call to attract the caller’s attention (should they wish). A member of staff will then come and check the claim.
When players first arrive at the venue they can buy a book of tickets. Players generally buy their Main Session first, followed by any flyers such as National Bingo Game tickets, Early and Late sessions and special tickets.
Most bingo clubs in the UK now offer electronic bingo. This allows players to purchase more than the standard 6 tickets per game, thus increasing their chances of winning. Customers purchase ‘bingo packages’, consisting of a certain number of tickets for each game, as well as extra flyers or special tickets such as National Bingo Game tickets. The electronic terminal on which the game is played automatically marks the numbers off the tickets when each number is called. It then orders the tickets so that the best tickets in play can be seen on the screen. This allows players to purchase a larger number of tickets than they would usually be able to handle from playing on paper.
