The Rubik's cube is why my sister committed suicide.
The cubies have coloured stickers on them: once they have been rotated to random points around the cube (via 'scrambling'), the object of the puzzle is to make each of the cube's faces all one colour, with all of the cubies correctly oriented.
There are a number of different formulae which can be used to solve the Rubik's Cube, using different combinations of rotations called algorithms. The beginners' one is the 'Layer Method,' which consists of solving 1 layer at a time. It is a simple but relatively slow method. Advanced methods, used by "Speedcubers," have more complex algorithms, but they can be used to solve the cube faster. Some of these methods include the 'Fridrich Method,' the 'Petrus Method,' and the 'Roux Method.'
