Kazunori

About Kazunori

A Nikoli-style domino number puzzle. Place numbers in regions so each number appears exactly twice in adjacent domino pairs. No 2x2 same-number blocks.

Description provided by GameZipper.

How to play

1. The grid is divided into colored regions with thick borders. Each region has an even number of cells.
2. Click a cell to cycle through numbers 1 to N/2 (where N is the region size). Each number appears exactly twice in its region.
3. The two cells with the same number in a region must be orthogonally adjacent (sharing an edge).
4. No four cells with the same number can form a 2x2 square anywhere on the grid.
5. Black circle numbers on region borders show the sum of the two adjacent cells. Use these to deduce correct numbers.

Controls

This game supports touch, keyboard, mouse input; the exact controls are explained inside the game.
