Ah, kingdomino got an award. I got a copy last year from a friend who picked it up at Essen. It is excellent. Pretty easy to learn, plays in 15 minutes, hidden depths to strategy. Great gateway game, and not too expensive either.
My only house rules are to remove the bonus points for a full board and centered castle, and to allow someone to declare a broken board and discard a tile at any time (instead of discarding their last tile).
Yeah, I don't like playing with the full board and centered castle for bonus points variants either. It seems unnecessary in most games, and just punishes someone who has a slightly less optimal board even further (they're probably not going to win it anyway).
