Tile Sudoku · Curve – 4×4 special
(Published on 14. August 2026, 06:30 by Todd)
Who cut up my sudoku?
Assemble the 16 tiles into a complete 4×4 sudoku grid, subject to:
- Sudoku: Digits 1–4 appear once in every row, column, and 2×2 box.
- Edges: Frame and box borders are thick; edges inside a box are thin.
- Curves: Blue curves on neighbouring tiles must join across shared edges. In the finished grid, every curve forms a closed loop.
Tiles may not be rotated or flipped. The puzzle has a unique solution.
Example of a completed 4×4 assembly — this is how the tiles fit together:
