In the Bingo Mania app, users are given a random grid of numbers at the start of each game. As the numbers are called, the app automatically marks the corresponding numbers on the user's grids. The objective is to complete a specific pattern, such as a straight line (horizontal or vertical) or a diagonal line, by checking off the numbers. Once a player has completed the required pattern, the game automatically ends and the user wins. The first player to successfully complete the pattern wins the game. Once the game is over, a new game automatically begins.
