The object of the game is to collect cards in one�s hand totaling as close to 31 as possible in the same suit. So here's my first card-it plays the game Scat, also known as 31, Ride the Bus and Blitz. Keith Vetter : I realized that over my 20+ years of programming that I've written hundreds of games but never a playing card game (actually I once wrote in Lisp an expert system that plays the game of canasta but that only played one hand and had no UI).
