Rubik’s Cube Keyring Edition. Classic 3x3 Mini Cube Keyring Accessory. The Rubik’s Cube is a classic colour-matching puzzle that can be enjoyed at home or on the move. We love it so much that we decided to make a small portable travel cube so that there is never a dull moment wherever you are! The Rubik’s Cube features six different sides, each made up of nine colourful squares. A must for puzzle lovers, the aim is to try twist and turn the Rubik’s Cube to its original state, with every side having one solid colour. There are... wait for it... 43,252,003,274,489,856,000 ways of arranging the squares, and only one of these is the solution. Turn and twist away; can you solve it? The new and improved Rubik’s Cube features a mechanism that results in a smoother, faster and more reliable play. The traditional stickers have been replaced with plastic tiles which means no fading, peeling or cheating!
