Lunomino

Lunomino is a card game where you try to get five in a row with suns and moons through playing your domino shaped cards 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
