1000 Blank White Cards is a public domain card game, which allows the players to make the cards during the course of the game. There are no initial rules, and while there may be conventions among certain groups of players, it is in the spirit of the game to spite and denounce these conventions, as well as to adhere to them religiously.
Card Content
Cards may feature a title, a picture, a score, a rule, or any other content, and need not be limited to one side or even to a single card. Early iterations of the game included cards with attached objects, and cards of a variety of sizes and shapes within the same deck and gameplay session. Many cards in later decks have a point value, but this is by no means a requirement.
Cards generally include hand-drawn pictures. The game encourages quick sketches by non-artists, which can add to the overall ironic orientation of the game. Card illustrations can represent anything the designer wants to feature, from serious to absurd. (However, usually cards tend toward the latter.)
