Based on mathematical principles that have challenged generations of mathematicians.
The set contains 30 different cubes, plus a 6 x 5 grid and a puzzle/solution booklet. Each cube features the same 6 base colours. The order of these colours varies from cube to cube. Every side on every cube features part of a *line*. The line appears in 10 different colours. The puzzles all require the lines and/or base colours to be connected in different ways, following increasingly complex rules.
The 45 multi-level challenges, including 10 junior puzzles, represent just a start of what can be achieved. There is a whole world of puzzles waiting to be created by you. Challenge your friends and family and pass on this amazing set to future generations.
