Magic Maze

The idea behind Magic Maze is actually pretty simple, as are (theoretically) the rules. You and up to seven friends take the role of four Dungeons & Dragons characters engaged in a petty larceny at a labyrinthine local shopping complex. Against a three-minute sand timer, you guide the characters around a walled maze, one move at a time, to find and steal weapons. The yellow barbarian must nab the yellow sword, the green ranger pinches the green bow, and so on. Once all four characters make it to their armaments, everyone scrams for the exit.
Here's what makes the game interesting: each player controls every character simultaneously, but only a few actions. In an eight-player game, you may only be able to move characters south, while your friend can only open doors, or move characters up and down escalators. Everyone has to coordinate…but nobody is allowed to speak. You can stare intently at your friends, or place the game's "Do Something!" figure in front of them, but you have to silently hope they realize what it is you want.
