If you like to be challenged and to make that already big brain even bigger, you need a puzzle that’s tough enough to take some brain power, but interesting enough to keep you interested. With the Gearblox Puzzle, that’s exactly what you’ll get.

All you have to do is try to match up the colours on each of the 6 faces – but it’s not that simple! This brilliant puzzle is made up on a series of gears and blocks that cause it to change shape every time it is turned – meaning that although it’s pretty tough to figure out, you won’t ever get bored because your puzzle is always changing!
