SOLVE MY CUBE GUIDE

Why won’t my cube colours fit?

If the app skips a colour you are trying to enter, it does not necessarily mean your physical cube is broken. Most problems come from a missed tile or a face entered the wrong way up. Start with those checks.

Check your orientation first

Return to white centre on top and green centre facing you. The red centre should be on your right. For each face you enter, check the coloured markers above, to the left and to the right of the on-screen face. The top and bottom faces are particularly easy to enter rotated.

Centres are your reference points. A scrambled face is named after its centre, not the colour that happens to cover most of its tiles.

Check the colours and cube type

A standard six-colour 3×3 cube has nine tiles of each colour. This app keeps the six centres fixed, leaving eight tiles per colour for you to enter. White is opposite yellow, green is opposite blue, and red is opposite orange.

The app also expects red to be on the right when white is on top and green faces you. If your cube has a different colour scheme, pictures or a different size, its entry may not fit. That does not make your cube defective; it means this version of the solver does not support it.

Nine of each colour is not the whole check

Tiles belong to physical pieces. An edge has two colours and a corner has three. On this colour scheme, white and yellow cannot appear on the same piece because they belong to opposite faces. You also cannot have two copies of the same edge piece.

The app checks whether each partial entry can still be completed into a reachable cube. It may block a choice because of something entered on a different face. Try Undo tile, clear the face you are uncertain about, or revisit earlier faces.

Some arrangements really are impossible

A cube that has only been scrambled by normal layer turns is still solvable. However, taking it apart, twisting a corner in place or moving stickers can create arrangements that normal turns cannot fix.

• One flipped edge: a single edge is reversed while every other piece is solved.
• One twisted corner: one corner is rotated in its slot while the rest of the cube is solved.
• Just two swapped pieces: two edges, or two corners, have exchanged places while all other pieces are solved.

These examples fail the cube’s orientation or permutation constraints. The app checks those constraints as part of validation, but it does not inspect your physical cube or diagnose which repair it needs.

A calm way to start again

1. Check the centre-colour layout against the one above.
2. Use Cube Reset if you are unsure where the entry went wrong.
3. Enter one face at a time, paying close attention to its top and side markers.
4. If a colour becomes unavailable, check the most recent faces before changing more tiles.

If the cube was dismantled or altered and you are confident the entry is correct, follow the manufacturer’s guidance or ask an experienced cuber to check its assembly. Avoid forcing a piece just to make the app accept it.
