We've had the game for almost a year and we've only played it when it arrived.  Frankly, my 5 year old daughter and I didn't find it as much fun or as stimulating as expected based on the positive reviews.  Main complaint is that the pieces are INCREDIBLY flimsy (has a home made feel) and one has to manage that aspect instead of fully focusing on the important things.  My secondary complaint is that the game is barely more involved than the basic memory card games that cost much less and no where near as challenging as Zoombinis software, which we love.  So, this game is not much fun, not well made, not very stimulating, yet it carries a relatively high price - avoid it!
