Challenge your mind with this knotty little puzzle by Dutch inventor Guido Lap.

String Theory

This knotty little puzzle is all about thinking inside the box. The brainchild of Dutch inventor Guido Lap, it uses simple elements to stretch your spatial reasoning to new limits. Elastic bands connect colored buttons on opposite sides of a clear, plastic case. Your challenge is to group the buttons by color, sliding them along the slots cut in the clear plastic, without getting yourself (and the cords inside) all tied up in knots. A great brain-teasing puzzle for older children and adults. Made in China.

Brainstring was developed by Dutch inventor Guido Lap. Guido combined an elegant design with an intellectually challenging concept and it was an instant success in Europe. Inspired by that success, he has worked with various inventors throughout the years to produce smart, unique, artfully-designed puzzles that appeal to puzzle-enthusiasts worldwide.

Very durable; easy to handle; open-ended progress. Easy to make as difficult or simple as desired. The colors are vibrant. The sound it makes--the clicks--are pleasant.

This was the perfect gift for my brother-in-law who is super smart, and really good at puzzles. He can make it super difficult for himself, or not as hard depending on the day, and he leaves it on his desk for quick brain releases. I love it!!!

My husband got this for Christmas from one of the kids and we all fought about who got to play with it first. It's really interesting looking and at first you think it will be super easy to solve, but it took us several days and multiple tries to get it solved the first time around. Very interesting puzzle.
