I have developed a working logic grid puzzle card game patterned after Clue. It's a race to find the murderer. All clues are public unless you want to give weaker players some private eye clues to give them a head start. The card game creates valid logic puzzles and reveals relevant clues of the same type we have here on this site (except any ordinal clues like time or cost). I'm still working on a few bugs as late in the game, the chances of getting a useless clue increases. If I cannot sell the game idea to the Clue franchise, who would be interested in seeing a print-and-play version? Of course, I would probably have to remove the Clue theme.
