...Interesting from the viewpoint of information theory, similar to optimum bidding strategies in Bridge. Synopsis: There are 5 suits, with values 1-1-1-2-2-3-3-4-4-5 in each. Each player has a hand of 4 cards, which are held backwards so the player can see everyone else's cards but not his own. The goal of the game is to cooperatively lay down a perfect solitaire style meld of 1-5 in each suite. On each turn, a player can either play a card, discard a card, or give jotto-style information to one other player. http://boardgamegeek.com/file/download/9gg381aeug/hanabi_rules_-_card_1_corr...
