Bingo is a classic and timeless game of chance for 3 or more players. 

The game is managed by a caller, whose job it is to call out the numbers and validate the winning tickets. As each number is called, players check to see if the number appears on their tickets.
 
If it does, they mark it off with a cover piece. When all the numbers required to win a prize have been covered, the player shouts out "BINGO" in order to attract the caller's attention.
