When playing the 'cube', the main challenge is that positioning one cubie can often result in other cubies becoming disarranged.
To tackle that issue many Algorithms are developed. But what algorithms really do not really solve the problem but just change the 'nature' of the problem'.
(In other words: algorithms help solve the problem of determining which rotations to execute to solve the cube, but they also create a new set of problems that need to be addressed. These include:
- the need to know all the necessary algorithms to solve the cube
- remember them,
- choose the right algorithm for the specific situation
Moreover, many of these algorithms are so complex that they seem like mysterious, incomprehensible formulas.
The 'DIY method proposes a slightly different approach in which, for the majority of cases, the use of an algorithm emerges as a logical consequence of the various possible moves. In fact, you will see that in many cases, non-optimal moves will be chosen as long as the resulting algorithm is always the same: the sledgehammer. (When the user is able to independently identify better moves, that will be the signal that this tutorial has achieved its purpose.)
In the more complex cases (usually towards the end.) the sledgehammer will be used for its general properties:
- Swapping between two cubies
- Rotating the stickers on a cubie
- Rotating the edges
(These properties will be described later using 3D models.)
