How to Play Suguru
Suguru was invented by the Japanese puzzle maker Naoki Inaba. Two rules, no arithmetic, and a surprising amount of deduction.
The rules
- The grid is divided by bold lines into regions of one to five cells.
- A region of k cells contains the digits 1 to k, each exactly once.
- Equal digits never touch, not along a side and not at a corner.
Playing on kawu
- Tap a cell, then a digit on the pad (or type it). Shift + digit, or notes mode, pencils in a candidate.
- Digits that break a rule are underlined in red.
- Undo steps back; Hint fixes a wrong digit or fills the most constrained cell.
- Sizes 5×5, 6×6 and 7×7; the daily puzzle is a 6×6 shared by everyone.

Frequently asked questions
Can the same digit be in two different regions next to each other?
Only if the two cells don't touch. Equal digits may never share a side or a corner, whatever region they are in. Two cells apart is fine.
What goes in a region of one cell?
A 1, always. That also rules out 1 in all eight cells around it.
