Bingo is played by marking pre-set numbers on a card, a sheet of paper or an online interface to a series of randomly selected numbers. A bingo can be called by a player if an unbroken straight line of five spaces is made after marking the selected numbers.
A game of bingo is typically concluded after a winner has been declared. To declare a bingo, a player must be the first person to call out the word "bingo," after which the results are verified before the official confirmation of a victory. Bingo can be played as a recreational game or for prizes.
