E3 Bingo
From Mario Fan Games Galaxy Wiki
E3 Bingo is an event that is held from almost a month before E3 to the day after E3 ends. Before E3 starts, members can participate by filling out a card with guesses of what they think might be shown, or little events that may take place. Every time if one of a member's predictions come true, he/she can mark it down. If one managed to get a line going across his/her card (horizontal, vertical, diagonally), he/she will get a bingo along with an E3 Bingo Winner badge.
