This is a pack of colourfully illustrated cards bursting with maths puzzles that will put children and adult's maths skills to the test.
Each brain-teasing puzzle sorts out the boffins from the buffoons by testing their maths skills, including code-breaking, multiplication and arithmetic.
The cards are wipe clean and the pack includes a special pen, making the pack entirely self contained, easily portable and a great gift.
