Challenges for Game Designers is an app based on the book of the same name by Ian Schreiber and Brenda Brathwaite. The app contains a "deck" of 300 cards, one card per challenge in the book, plus a few extra challenges not in the book. If you have a few minutes and want to try a random challenge, just let it deal you a card, and go from.
