Preparing for a backpacking trip into the Grand Canyon, we wanted to bring multiple games with us. To save weight and space in our bags we put them all in one to create the first Flex Deck playing cards. Now children, families, service members, teachers, adventurers and others all over the world are starting to have a little more fun... Made by the United States Playing Card Company (USPCC). How To Play: We believe that house rules are official rules. By that, we mean you pick how you play the Flex Deck. Mix classic systems of fun with double-nine dominoes, word games and traditional card indices, all in one. Card Games to Play: Solitaire, blackjack, euchre, blitz, hearts, spades, rummy, gin, go-fish, crazy eights, egyptian rat screw, etc. Domino Games to Play: double-six dominoes, double-nine dominoes, texas 42, mexican train, blind hughie, one armed Joe, sniff, spinners, etc. Letter Games to Play: Build a crossword grid or enjoy variations of solitaire, hangman and poker among other rules that you may already know.
