Last three edges

Cycle and flip the three front edges to finish the puzzle.

Goal

Solve the three edges of the front face. After this lesson the puzzle is solved.

How to hold it

Hold it like the last lesson: the solved back corner at the back, green facing you. The three edges left are all on the green face.

How to recognize it

Count the green triangles on the three edges of the front face.

  • Three: the edges only need to cycle around. The left edge's color tells the direction.
  • One, on an edge that is not solved: the edges cycle and some are flipped. Note where that edge is and its other color.
  • One, on an edge that is fully solved: the other two are flipped in place.

Steps

  1. Count the green triangles on the three edges of the front face.
  2. Find the matching case in the tabs and do its main algorithm.
  3. Two flipped edges with the solved edge not at the bottom: turn the whole puzzle (z or z') to bring it down first.

Memory tips

The six cases with flips take only four turns each. The three long algorithms are each two four-turn algorithms joined, so learn the six short ones first.

Check

Every face is one color. Well done, you solved the Pyraminx!

Common mistakes

  • Counting green triangles on the side faces as front ones.
  • Doing these algorithms before the back corner is done: they only work after the last lesson.

What next

Solve it a few more times, then time yourself and see how fast you get.

Step 1 / 4

R': Two layers around the right corner: turns counterclockwise (looking at the right corner)

Only the left edge has green on the front; its other color is blue.

The solved back corner is at the back, green facing you.

Step 1 of 4: R'. Two layers around the right corner: turns counterclockwise (looking at the right corner)
