The blue Colour Block is a small wooden brain teaser from Professor Puzzle, the British games and puzzles publisher. It is the twelve-piece model in the Colour Block series: you take all the pieces out, mix them up, and the challenge is to rebuild the original shape.

How it works

It is an assembly puzzle: there are no linked pieces or mechanisms, just wooden blocks that have to fit together, filling exactly the space available. Taking it apart is instant; the hard part is remembering or working out where each piece belongs, and with twelve pieces the possible combinations multiply.

The series and its levels

The Colour Block series is made up of eight models (yellow, blue, purple, orange, black, red, pink and green), and each colour corresponds to a different design, with its own number of pieces. That is why it makes sense to collect them: they are not the same puzzle in a different colour. With twelve pieces, the blue one is among the most painstaking models in the series, along with the red, purple and black. Even so, its pocket format makes it manageable for short spells.
