Logic Puzzle Toy ■ Umbra Vertical Cube
My friend once gave me a very interesting puzzle from Japan After some research, I found that the mathematical principle behind this puzzle toy comes from Professor Hideki Tsuiki of Kyoto University in Japan
Suppose when light shines on a solid from three perpendicular directions, a square shadow is formed What is the shape of this three-dimensional object A cube is one answer and so is a regular tetrahedron
Such a three-dimensional object makes us imagine a cube determined by three square shadows I call it the 'Umbra Vertical Cube'
This is a puzzle designed with cubes where all three directional projections are squares All you need to do is fit all the cubes into this box and close the lid
Clues have already been set on the lid printing it out marks the start of the challenge
Solve it within 15 minutes and I'll call you a god
If playing this raises your blood pressure then you might as well play with the fidget toys below to balance your yin and yang (0v^) Click the picture to enter
