By one of the designers of cheapass games it consists of six decks of various difficulties. You play it as a rapid trick taking game trying to get the most base cards. You have special cards such as blocks (stop you laying down a color), clear (clear a base off the table with all the attached cards) and Freeze (stop playing cards on a base). One of the fastest filler I have played (two to four minutes at most and this with three people playing). I think the playability may wear off fairly soon but if you only have five minutes a really nice filler and decks are available for under ten dollars.
