From the publisher's website:
Hocus is a classic card game beloved by ancient folk, now redesigned for modern humans who may or may not have the gift of magic. It is about managing a limited hand of cards and wielding spells to create ranked sets of cards that are superior to your opponents’ sets. Using elements from classic Poker games, Hocus expands and revises them to create a fresh and magical experience. In Hocus, 2-5 players build the best Sets by combining shared Communities of 4 cards with 2 personal Pocket cards. Unlike in traditional Poker, players build Communities, Pockets, and Pots using cards from their Hands on individual turns. There are multiple Communities, each with a Pot, and two Pockets per player.
