Wizard Kittens is a semi-cooperative set collection card game. Players are wizard kittens who have accidentally released a few curses from the library's restricted section. Now they must defeat the curses before they're caught by the librarian; Professor Whispurr.

Each turn plays quickly but offers interesting decisions; most often around which spell to use and how to use it. Spells allow kittens to draw extra cards; sling cards at other players; discard cards out of their own play areas; or trade any two cards in play. No player can use the same spell two turns in a row; either.

The game ends when either the last of the six curses is defeated; or when the Professor Whispurr card is drawn from the ritual component deck. If the kittens defeated the last curse; then they tally up points (including a secret objective Extra Credit card); and the highest score wins. If they are caught by Professor Whispurr; then the Cleanest Paws Clause applies. All kittens with 10 or more points lose; and from those who are left; the kitten with the fewest cards in their play area wins.
