The Yoyleberry Method is an experimental novelty method for the Square-1 puzzle. The method reduces the puzzle to a cubic shape and later reduces it once more to a state similar to that of the Rubik's UFO. During this part of the method, single swaps of corners and/or double-edges are possible, and the triple corner swap during other methods can be easily done in this step in comparison to more commonly used methods.
- 1. Turn the Puzzle into a cubic shape.
- 2. Solve Edge Orientation intuitively. Corner orientation is irrelevant in this stage.
- 3. Bring the puzzle back into "Barrel / Barrel" shape. Consider the groups of double-edges as a single piece.
- 4. Group each double-edge with its corresponding pair of corners.
- 4a. Solve the first two corner-edge-corner quadruplets intuitively.
- 4b. Use an algorithm to solve the remaining two quadruplets.
- 5. Bring the puzzle back into a cubic shape by undoing step 3.
- 6. Permute both layers of the puzzle.
The name "Yoyleberry" is a reference to the animated series "Battle for Dream Island", created by Cary & Michael Huang. The yoyleberry is a fictional fruit that turns consumers into metal.
