Kumbu (2011)

"Kumbu is a memory game with an African theme and a twist, namely that the tiles have pictures on both sides. (Thus the name "Dubbelzijdig Memo", or double-sided memo.) When you play the game, you lay out the tiles, then take turns revealing two tiles to try to make pairs – but when you turn over a tile to reveal the other side, you don't turn it back if you fail to make a match. Thus, the hidden sides of the tiles keep changing throughout the course of the game. A player wins the game when he has the most tiles in the end. Kumbu includes multiple variants. "
