TRIBBLES CUSTOMIZABLE CARD GAME is a self-contained spinoff of the Star Trek Customizable Card Game from Decipher, Tribbles is a card game where you are trying to empty your 7-card hand in order to score points ("tribbles") that you have been able to play. Each card represents a certain quantity of "tribbles" (1, 10, 1000, or 10,000.) The game play follows a sequential order, with each player needing to play the next higher value of tribble out of his hand than the one played immediately before.The TRIBBLES CUSTOMIZABLE CARD GAME provides four preconstructed decks totalling 112 cards, which are color coded to fit a theme. These cards can be interchanged to create different decks. To make the game even more customizable, "tribbles" cards from the ST:CCG expansion set "The Trouble With Tribbles" are compatible with this game.
