Difficulty Rating 3 out of 5 = Dilemma 6 door-framed pieces with notches interlock to make a cubular shaped burr puzzle.
There are 4 different burrs in the series available in a discounted set click here.
The puzzle is an Eco Game made from Bamboo.
The philosophy of miToys use of bamboo is: Bamboo is a large grass which grows quite quickly in different climates around the world. It is an ideal substitute, plentiful and eco-friendly species to replace wood, which will help make our earth greener and last longer.
Size: 80mm x 80mm x 80mm The puzzle does come with a solution but it is printed quite small (seems they wanted to continue the 'environmentally friendly' theme) and leaves a lot to the solvers own ability.
