This is a really addictive little game.

It's an online game that puts you with up to 14 different players and you have to figure out who among you is a murderer and who is innocent. If you're a murderer you have to lie and manipulate your way around the other players and kill everyone before they figure out it's you. There's a full explanation of the game on the website but if you have a spare half an hour, give it a go.
