Bingo sheets are also known as scratch cards or lucky tickets. They are small, rectangular sheets of paper with a series of spaces or squares on them. The object of the game is to cover all the squares on the sheet with numbers from 1 to 35.
Bingo games typically have a number of different squares with different numbers assigned to them, and players try to fill in as many squares as possible by marking off numbers with a wooden or plastic marker. Prizes are awarded for each square that is covered, and the player with the most prizes at the end of the game is the winner.
Bingo games can be played at home or in a casino, and they are usually played with teams of two or more players. The game can be very addictive, and players may find it difficult to stop playing once they get started.
Bingo sheets can also be used for other purposes, such as as a means of tracking progress in a school project or as a way to keep track of expenses.
