A Bingo Masterboard is a tool used in the game of bingo to help keep track of the called numbers and provide a visual display for the players. It consists of a large board with numbered squares corresponding to the numbers that can be called during the game.
Bingo Masterboards are designed to be compatible with the US standard numbering system for bingo cards. In this system, each bingo card contains a unique combination of numbers arranged in a grid. The range of numbers used typically follows the format B1 to O75, where the letter indicates the column (B, I, N, G, or O) and the number represents the specific value within that column.
