In Matryoshka you are a collector of the famous dolls. There's just one problem – all sets are mixed up, and everyone has dolls that don't match! Swap cards with each other to complete your sets. Full sets are worth a lot of points, of course, but having different sizes helps too. Each turn, a player trades one of his dolls, and then everyone may make an anonymous bid. The seller chooses his favorite bid, and then the exchange is done! If you know how to bluff well, you can get exactly the trades you want. Can you complete your matryoshkas?
