There are now, of course, myriad puzzle games like this available on computers, tablets and phones. But handling the pieces and physically playing with the puzzle is different: It brings more focus (you're not flicking between screens constantly!) and there are no cheats or hints to be had, simply a challenge to overcome.
I got this as a gift for the xmas stocking and the whole family (all adults) enjoyed it over the holidays. There are plenty of different levels and the pyramid game was a nice twist on the 2D flat puzzle play.
