Strategic Bingo

In this game you play bingo with other players in a strategic way. Each of the players will hold a card with a grid of numbers on it, and once in a while, a ball will be drawn, if the number on the ball appears on your card, then you circle it. If your circled numbers form a whole line horizontally, vertically or diagonally, then you have made one line, and you have the choice to call "Bingo!" to score a point, you can also wait and circle more numbers until you get two lines and then you can call "Bingo!" to score two points, but if one of your opponents called "Bingo!" before that, then you cannot score that line you have already made. After that a new round starts with new cards for each player. The game ends when one of the players scored 3 points.
