Simple and clever idea for a game. Great game for younger kids (I play it with my 5 and 8 year old). The game mechanics are well designed and work well. The only "negative" thing I'd have to say is that there really aren't any exciting additions after you understand core mechanics of the game well. There is definitely opportunity for creative and different rules to change up the game, but I didn't find anything super creative. That said, I think there are expansions for this game that might solve that!
