Goal: make the current board exactly match the target pattern in as few moves as possible.
- Flip Row: reverse the selected row.
- Flip Col: reverse the selected column.
- Rotate 2x2: click the top-left tile of a 2x2 block to rotate it clockwise.
- Each puzzle has a target pattern and a par move count.
- Undo and restart are available while solving.
How Moves Work
- Flip Row on
A B C D A becomes A D C B A.
- Flip Col reverses that full column from top to bottom.
- Rotate 2x2 turns a block clockwise:
[A B / C D] → [C A / D B]
- Move types are deterministic: the same click always gives the same transformation.
- If a move seems unhelpful, use Undo and try a different operation order.
Solve Strategy
- Match one row or column at a time, then protect it while fixing the next area.
- Use Rotate 2x2 for local fixes and row/column flips for bigger rearrangements.
- Check the Par value as a benchmark, not a hard limit.
