Mysterium [official site] is one of my favourite board games. It’s somewhere between Dixit and Cluedo in that you’re a psychic trying to find a murder’s culprit, location and weapon but the only clues you have to go on are these wonderfully illustrated cards given to you by the “ghost” player which form your psychic visions. The game now has an official online version so I’ve been checking it out to see how it translates.
