The key to solving many puzzles is simple - a different perspective.
For the Rubik Cube, this change comes when...
| Instead of 54 squares || |
| ||You see the 12 edge pieces and 8 corner pieces on the frame of 6 centre pieces |
|And, instead of 6 faces, || |
| ||You see the cube's three layers |
Look at the three cubes below.
Only on the cube at the front has real progress been made.
- To the beginner's eye, the cube at the left is just as solved as the cube at the front.
- In reality, the cubes at the left and right are equally messed up!
But why is that so?
Sure, the left cube has a green face. But most of the pieces making up that face are still in the wrong positions.
|If the corner piece towards the right is correctly positioned, why is its yellow sticker next to the light blue centre piece? || |
|And the green and red edge piece surely doesn't belong where you see it either! || |
|Towards the back, there's two more pieces with a yellow (orange?) stickers, but on the face with the dark blue centre || |
|Ok, the corner piece at the front is correctly placed. It's three stickers match the colours of the centre pieces they are on. Beginner's luck, maybe? || |
By contrast, on the cube at the front, all the pieces on the top layer, not just the stickers on the top face, are in their correct places.
This, then ---> <--- is the key!
If you can solve one layer, then another, then another, you have solved the entire cube.
