I've been playing with this a lot over the past week. A friend of ours bought one each for their kids and kindly got an extra one which they thought Jason might like. Well, he does like it - a lot - and so does his Dad! It's tricky enough to get you hooked but not so frustratingly difficult that you want to hurl it against a wall and jump up and down on the pieces (not that I've ever done that, I hasten to add!)
It's a really ingenious toy and intriguing just figuring out how someone might have gone about designing and making it. You can buy this and other edutainment-type puzzle games/toys at shops inside the Taichung Science Museum.
