Brainstring 3D Puzzle

Whether you're 7 or 70, this 3D puzzle will bring your intuition and structured thought capabilities to their very knees...and what's more, you'll be begging for it!

The Brainstring Puzzle allows endless hours of addictive fun - an ingenious pattern of buttons and strings can be moved over a transparent cube and if you're not careful, a number of complex knots will start to develop.

Brainstring is brain-thrashing fun at its best...and once you've mastered the basics, have your friends and colleagues tied up with your own knot creations.
