Players: 2 to 6
Required: Zoo deck
SET UP
Each player places 4 cards face-down to mark four columns. The rest of the deck is dealt out evenly among the players and any remainder set aside.
HOW TO PLAY
Draw cards one by one and place them face-up above the other card/s in one of the 4 columns.
When you manage to line up 4 cards of matching Cost, Beauty, Ferocity, Rarity or Set, you may remove them from the game and set them aside. You may line up cards horizontally, vertically or diagonally. Move any cards above the popped cards down to fill the gaps.
It is possible to chain pops. It is also possible to achieve second-level vertical pops of more than 4 cards in length.
The game ends when someone runs out of cards. Each player counts their remaining cards, both on the table and unused in their deck, and the lowest score wins!
