Lanterloo or Loo is a 17th-century trick taking game of the Trump family of which many varieties are recorded. It belongs to a line of card games whose members include Nap, Euchre, Rams, Mao, Hombre, and Spoil Five. It is considered a modification of the game of "All Fours", another English game possibly of Dutch origin, in which the players replenish their hands after each round by drawing each fresh new card from the pack.
