This is a pretty fun game.  It's definitely a solo game.  The mechanics are completely you against the dice.  However it's fun and engaging when shared with others.  Unlike most solo dice game, this is not one that plays itself.  There's definitely a decision making process involved with each turn.  The rules and mechanics are simple to pick up and play within a matter of mintues, and yet has the replay value to amuse yourself with by playing again and again.
