Rubik's Solver

Pyramorphix Solver (2x2 pyramid) — 3D

Turn the 3D Pyramorphix below just like the real toy: drag to rotate the view, pick a colour and click the stickers until the model matches your puzzle exactly, then hit Solve!. Quarter turns shape-shift the puzzle — the animation shows every wild in-between position.

How to solve your Pyramorphix

When this tool helps

Use this solver to restore the colours of a Pyramorphix that starts in its pyramid shape. It is particularly useful when the outline looks solved but the colours do not, or when you want to understand why an apparently sensible turn changes the shape. An already irregular starting shape cannot be entered in this painter.

Check which puzzle you have

A four-colour pyramid with four triangles per face when it is in its tetrahedral shape. It has four three-colour corners and four one-colour pieces. Unlike the Pyraminx, a quarter turn changes its outline.

Before you press Solve

  1. This colour-entry model starts in the pyramid shape. If your physical puzzle is an irregular shape, bring it back to a tetrahedron before copying the stickers. The painter cannot describe an arbitrary starting shape.
  2. Match the four labelled faces: Upper Left, Upper Right, Lower Front and Lower Back. Copy both the single-colour centre triangle and the three surrounding corner stickers on each face.
  3. Keep the Lower Back centre piece as your grip reference. Its position stays fixed in this solver’s frame. Do not switch to Pyraminx instructions merely because both toys are triangular.

Read the moves

The move names U, R and F refer to the three turning blocks shown in the animation. A plain letter is a quarter turn, an apostrophe reverses it, and 2 is a half turn. These are not the small tip turns of a Pyraminx.

    Follow the answer on your physical puzzle

    1. Before following the answer, compare the four one-colour pieces and all corner stickers with the model. Keep the Lower Back reference piece in the same place; similar-looking triangular faces make an accidental change of grip easy to miss.
    2. Advance one move and identify the entire turning block before moving your toy. A quarter turn can leave projecting corners where a flat region used to be. Preserve that intermediate shape and proceed to the next instructed turn instead of adding a turn to restore the outline.
    3. Check the finished result in two ways: the puzzle should have its tetrahedral outline and each face should be one colour. A pyramid outline alone is not the target. Logo or picture orientation on a one-colour piece is outside this solver’s colour model.

    Turn the result into practice

    The worked example uses two half turns, R2 followed by U2, so its starting position is still paintable as a tetrahedron. Follow its undo sequence and watch the outline during the turn, then compare only after the full half turn finishes. This links the mechanism’s shape changes to the colour diagrams without pretending that the input screen can represent every possible shape.

    Practise with a reproducible setup and illustrated undo sequence below.

    A pyramid-shaped starting position with mixed colours

    Start with a solved Pyramorphix and perform R2 followed by U2, using the turning blocks in this solver’s notation. Each half turn ends in a tetrahedral shape, so this is a position you can copy into the painter. Keep the Lower Back centre as your reference.

    For this exercise, begin with a solved physical puzzle. Make the setup moves below before following the undo sequence. The example replaces the model’s colours; it cannot change the puzzle in your hands.

    Match the diagram’s reference colours

    Upper Left: green; Upper Right: blue; Lower Front: red; Lower Back: yellow. Your toy may use a different scheme. Match the face positions and move directions rather than re-sticking the toy to match these colours. Each face is shown from outside; the diagrams are face maps, not cut-out assembly instructions.

    Set up: R2 U2

    1. R2: Twist the RIGHT edge block — the wedge along the right edge, where the Upper Right and Lower Front faces meet a half turn (180°, either direction).
    2. U2: Twist the TOP edge block — the wedge along the top edge, where the Upper Left and Upper Right faces meet a half turn (180°, either direction).

    The half turns were chosen deliberately. An arbitrary quarter-turn scramble can leave an irregular outline, which this tetrahedral colour-entry screen cannot represent. Being able to animate a shape-changing path does not mean the painter accepts every possible starting shape.

    Undo: U2 R2

    1. U2: Twist the TOP edge block — the wedge along the top edge, where the Upper Left and Upper Right faces meet a half turn (180°, either direction).
    2. R2: Twist the RIGHT edge block — the wedge along the right edge, where the Upper Right and Lower Front faces meet a half turn (180°, either direction).

    2. After R2

    Sticker letters: W white · Y yellow · G green · B blue · R red · O orange.

    U2 undoes the most recent half turn. R2 then restores the face colours. During a half turn the mechanism passes through other outlines; compare the diagrams only after completing the turn. Do not twist a small tip as if this were a Pyraminx.

    This undo sequence is guaranteed to reverse this setup. It is not a general recipe for every scramble or a promise of the shortest route. The automatic solver may find a different valid answer.

    Then press Solve and compare its answer with the worked route. The diagrams and written steps above remain available without JavaScript or WebGL.

    When something does not match

    The model changes shape. Is the animation wrong?

    Shape changing is part of the mechanism. A quarter turn exchanges flat pieces and projecting corners. Follow the sequence in the original grip; the target is a tetrahedron with matching face colours.

    The site rejects the colours I entered.

    Check that each face has one centre triangle and three corner stickers, and that the four centre colours are distinct. A corner has three stickers whose order matters; matching only the colour totals can still describe a mirrored piece.

    Can it align a logo or a picture on a centre?

    No. The solver treats the orientation of a single-colour piece as invisible. It solves the face colours, not a logo, grain direction or picture printed on a sticker.

    For help with colour entry, grip and playback, read the solving guide. See three illustrated positions with correct counts that still cannot be solved. If the result still looks wrong, send a reproducible bug report.

    What this solver guarantees

    Our exhaustive tests reproduce 136,080 distinct positions after equivalent orientations are identified, and a maximum shortest distance of 9 twists when a half turn counts as one. The limit is nine, not eight; it is specific to this move metric.
