RECENT TOYS Pyraminx Diamond logic puzzle

The Pyraminx Diamond is a logic puzzle in octahedron form with eight triangular faces, each of which must end up showing a single colour. The aim is to twist the sides until the colours are mixed up, then turn the pieces until every face is one colour again. If you have already solved the classic Pyraminx Duo, this is a considerably bigger challenge.

The corners can be turned, and the inner section moves with them. Every move therefore becomes a thinking step that calls for concentration and planning ahead. The game is suited to indoor use and is intended for children aged roughly 8 to 10 years.

Weighing 150 grams, it sits comfortably in the hand and is easy to take along. It is a tricky alternative to classic logic cubes for anyone who enjoys puzzling things out.
