"Double or Nothing is a concrete novel in which the words become physical materials on the page. Federman gives each of these pages a shape or structure, most often a diagram or picture. The words move, cluster, jostle, and collide in a tour de force full of puns, parodies, and imitations. Within these startling and playful structures Federman develops two characters and two narratives. These stories are simultaneous and not chronological." -Worldcat summary
