The Great Sherlock Deck turns the works of Arthur Conan Doyle into a unique 60-card deck based around thirteen well-known Sherlock Holmes mysteries. It's family fun for ages twelve and up so anyone can play. Each of the six card games included in the rules book plays like a classic card game, so it’s easy to get started and join in on the fun.    • Play Mysteries, a variant of Go Fish, as you try to collect all the clues for as many of the thirteen mysteries as you can.   • Declare It’s Elemental in a variation on crazy eights where you work to get rid of all the cards—and clues—in your hand.   • Try the Sherlock Snap, where you play the classic game of snap by matching the same type of clue from different mysteries until someone else is left holding all the cards at the end.
