Ĝaberŭoko

Ĝaberŭoko (Jabberwock) is a trick taking card game with an Alice in Wonderlands theme where players must fulfill different contracts (20 available), sometimes trying to take some specific cards, sometimes avoiding them.
The game contains standard Ace->10 cards and three different Jabberwocks in each color. The Jabberwock is a trump card that comes back in the hand of a player and immediately evoluate to a less powerful version of himself. Only another Jabberwock can beat him.
Because it's not good to have Jabberwocks in your hand at the end of the game, you'll have to find the right balance between taking cards with the trump and trying to weaken it to give it to someone else.
