In??Flipology- players try to score the most points over three rounds. At the start of the game- each player receives nine cards- then picks seven of them to arrange in a face-down row. On your turn- you must flip one of your seven cards (up or down)- with some cards having effects that enable you to flip additional cards- including those owned by opponents. Cards depict animals in different types of environments- and they have different effects and point values depending on whats shown at rounds end- such as the sloth which is worth positive points only if its still face down. Aside from sloths and koalas- though- cards must end the game face up to contribute to a players score. In the Great Tree variant for 2-4 players- five cards are dealt to each player and two turns are taken. Then a second set of five cards cards are dealt out which go above the first row and two more turns are taken- with the added wrinkle that players now control two rows and adjacency means up and down as well as side to side. Finally- a third set of cards is dealt out and players take a final two turns- then calculate their total score. - Description from Publisher AGES 6 2-8 PLAYERS
