Purchased this three years ago for a 5 and 6 year old.  They are now 8 and 9 and still love this game.  The age range should be 5-adult since it's just a fun for adults.  This game requires only a few elements: strategy, luck, bluffing, and math.  Each round can take from 1-5 minutes and people of every age are matched pretty evenly.  The kids win as often as the adults - which is a good thing - without the parents having to "let" the kids win.  This is the game the kids keep in rotation all the time while other games have gone to the back of the game drawer and game closet.  Daughter has taken this to school a few times and everyone loved it. When the kids want to play a game with me, I often suggest this one.
