A World of Categorization: The World of Clades

Matchmakers Ready: Gameplay Basics

In Clades, 12 cards are placed face-up on the play surface. Players race to identify sets of three animals from the same clade, such as three mammals or three arthropods.

The player who spots the match wins those cards.

Each player also has a secret card which can be used to make matches. Play solo or race against other players to see who can make the most matches.

The instructions include rules to assist new players and balance the game.
