A game of late-night deduction and coffee for two or more players. Object: To figure out the secret rules that govern how the other players move pieces on their turn. You Need: * An area with diverse items that you can group in general categories. A table with four place settings at your local late-night diner should do nicely. * Paper and pencil for each player. Each player makes up a rule and writes it down. The player's rules dictates how he moves pieces when it's his turn. On each player's turn, the player moves a piece in accordance with his secret rule and then asks a yes/no question to another player. Players can also guess other players' rules for points. The game ends when all rules but one have been guessed. If your rule remains unguessed, then you lose 1 point. The player with the most points wins.
