Lunomino

Lunomino is a card game where you try to get SIX in a row with suns and moons through playing your domino shaped cards/CARDBOARD right. On the cards, there are castles, (sun- and moon castles) and rainbows. The cards are played by putting half your card on your opponent's moon (or sun) and the other half of the card covering the table. You can't cover your own symbols. —description from the designer 6 in a row much more fun still same picture
