How to play Suguru
Also called Tectonic. The grid is split into outlined regions of 1 to 5 cells.
The rules
- A region of n cells holds the numbers 1 to n, once each.
- The same number can never touch itself, not even corner to corner.
- Every puzzle has exactly one answer.

One-cell regions are always 1.
Look at a number’s eight neighbors: none of them can hold the same number.
In a 2-cell region, the cells are 1 and 2: find which way round.
Tips
- Fill the small regions first.
- Large numbers (4 and 5) only fit in big regions, so they are easy to place.
