In Bingo, players aim to complete specific patterns on their cards, and the Postage Stamp is one such pattern. It involves marking four numbers in a block, usually in one of the corners of the Bingo card. Once all four squares in that corner are marked, the player can win if the game calls for this particular pattern.
Postage Stamp Example
For example, if a player marks the top-right corner of their Bingo card with four adjacent numbers, creating a small square, they would have completed a Postage Stamp.
