It may not be hi-tech but this is frustratingly addictive and will give your brain a real workout. The idea is to create one of 6 large geometric shapes such as a square, pentagon, circle, etc from smaller irregular shaped pieces.  The thin cardboard shaped pieces are colour coded. All retain their colour and only one shows the signs of slight damage. The box is in near perfect condition with only slight surface discolouration on one side. Luckily the solutions are also included.  They appear a bit grubby with an ink stain on the inside but this is evidence that they have been well used. An ideal item for a quiet activity on a family holiday, a vintage toy collector, a prop in a production or for someone who enjoys geometric puzzles.
