The Lin method is a speedsolving/novelty method for the Square-1 puzzle.

The steps

  • 1. Turn the puzzle into a cubic shape.
  • 2. Build the first two blocks.
  • 2a. Build a 1x1x3 block on the bottom layer of the puzzle, either the left or the right side.
  • 2b. Build a second block in the bottom layer, opposite the first one.
  • 3. CP + DF (Corner permutation + DF edge)
  • 3a. Insert one of the two remaining D edges.
  • 3b. Insert the last one in DF (from UL) while simultaneously permuting the top layer corners. This step requires 6 algs, specified below. A two step approach, first inserting the edge and then permuting the corners, is possible. This approach requires around 2 algs, which are basic Vandenbergh algs.
  • 4. EPLL (excluding corners)

PLL + 1

Alternatively steps 3b. and 4. can be combined into 1 step which solves the DF piece and everything else. This step is called PLL + 1 and has 72 algorithms excluding the 21 PLL algorithms. It is much faster than CP + DF / EPLL but has many more algorithms so there is a tradeoff. It is important to note that PLL + 1 only works if you use CSP because parity is not accounted for in any of the algorithms. PLL + 1 is implemented by most top Lin solvers.
