A great variant of the soma 3x3x3 type puzzle. The total number of pieces is 6 rather than 7, and the different shapes means that there is only one correct solution. It took me hours to figure it out. Great way to work out the brain!

My 10 year old grandson is obsessed with this puzzle. Hasn’t solved it yet. Finally.. he’s stumped on a game that will hold his attention.

Great quality, and met our expectations!

I made a mistake when I ordered this item. The seller bent over backwards to help me make it right! I have already placed a second order with this shop! The best part, it allowed my son to practice and took first place in his division at the district level :)
