Nexcube 3x3 keychain

The NEXcube 3x3 is a keychain puzzle in the form of a classic 3x3x3 speed cube. It attaches to your key ring, so you can carry it with you wherever you go and take it out whenever you have a few spare minutes. The principle will be familiar from similar logic puzzles: turn the faces until every side shows a single colour again.

The task is simple to understand but takes patience and practice. The aim is to rotate the sides so that, in the end, each face displays one uniform colour. It is a good way to test your logical thinking, and you can also time yourself to track your progress.

A small pastime for in between, whether you are waiting somewhere, on the move or at home. Start it on the way and finish the puzzle later at your leisure.
