When the battle begins, each player receives a randomly selected bingo card. As you collect the objects and enemies shown on your bingo card, the corresponding square is activated. To win the battle, you must create a straight line of four active squares—the active squares can be aligned horizontally, vertically, or diagonally.
When a player activates three squares in a line, a notification appears on the screen. The square needed to complete the line is then highlighted on that player’s bingo card.
