C.O.G.: Shifting Gears is an 9-card pack that transforms the base game C.O.G. into a quicker and more portable version without sacrificing any of the interesting and intriguing aspects of the original game. C.O.G: Shifting Gears converts COG into a portable game by replacing the game's main board with a few cards. This variant also shortens the game by changing the goal into a race to complete words, as opposed to a competition over victory points. Also, instead of completing the usual 10 or more words per game, the game ends when a player has completed only 4 words. However, using the goal tiles from the original game, you can add variety by changing both the words and the number of words. -description from designer
