Visual images have been a key element in the development of wager-based games. The legacy of visual metaphor in gaming can be traced through paper ephemera such as playing cards and lottery tickets. Both paper and printing technology ushered the age of wide spread playing opportunities in the 19th and 20th centuries. Modern play behaviors have given way to Postmodern gaming norms in digital space. The digital age has presented a new set of challenges for gaming architecture in wager-based play. Action research in prototyping games is beginning to reveal a new and different set of game characteristics.
