Loo

Loo (originally lanterloo, a word of Dutch origin), a round game of cards. Each player places in the pool a certain number of coins or counters (either three or some multiple of three), which are termed his "loo." The dealer, whose stake is double that of the others, deals three cards to each player and an additional hand called "miss." The card which remains at the top is turned up as trump, and the cards rank in all respects exactly as in whist. The player on the dealer's left then examines his cards and determines whether he will "declare," "withdraw," or "take miss." A player who declares and loses the trick is "looed" - i.e. he pays into the pool a fine equal in amount to the stake.
