Schlafmütze (2005)

Schlafmütze is a card game of set collection, sly hand movements, and social observation for 3-7 players ages 5 and up. Players try to collect 4 matches of a drowsy character. The first player to do so subtly places the set down on the table in front of him. The other players, noticing this, place their own cards, matching or not, on the table. The last person with cards left in hand is the sleepyhead and must take the "sleeping goblin" token. Source: user summary
