Is it a book? Is it a game? Playniac’s award-winning crowd game Cat On Yer Head is now both. This game for 20 to 1,000 people has been played at parties, festivals and events all around the world. A session is typically run by game designer and Playniac-founder Rob Davis, but a new book, already an IndieCade Official Select 2014, now lets anyone run it wherever they can get a few friends together. Cat On Yer Head starts with a few simple rules that can then be modified while it is played. An imaginary cat, passed between players, chases an imaginary mouse who must escape it and eat cheese; or hide down a mouse hole; or turn into a cat-eating monster - or whatever the players invent. Because that’s the aim of the game: to build upon its basic rules, redesign it on the fly and make it sillier while you play.


The game has been featured at over 17 festivals and events, including GameCity (Nottingham), GameCamp (London), Edinburgh Fringe and GDC Europe (Cologne) and played in game design classes and at schools. It was played at the IndieCade Red Carpet Awards at the Museum of Contemporary Art (Los Angeles) as an Official Select 2013. The newly released Cat On Yer Head Storybook is available in digital and print editions. It features over 30 illustrations by Jerry Carpenter, creator of the Game Toilet comic series on Brandon Boyer’s Venus Patrol web site. The book gives players an introduction to the basic rules, before introducing some quirky extensions to get the game going. Next, it gives numerous variations created by players: the elephant, the were-mouse, the sardine smart bomb and many more. Participants can try the variants for themselves, or even better start inventing their own. Either way, the game will often have the crowd in hysterics. In 2015 Cat On Yer Head was adopted by the Mayor of London and UKIE's Digital Schoolhouse London Programme to teach game design in London Secondary Schools.
