This model goes up to 12 and is designed so 2 can play at the same time.  Over 30 years ago my brother David thought Drueke should make a 2 sided version of this game.  We didn't do it.  NOW, here it is!   This traditional game has been around all my life (66 years).  When my Dad sold the Drueke Game business in 1986, I was president.  I still enjoy playing Clapper.  A great game that can be played alone or with any number of players.   Includes easy to follow instructions and 2 pair of dice.  Well constructed  game made of beautiful hardwood.   The size is 11-1/2  x 13.  A great game for any age!   Try it you'll be hooked on it!
