How to Play Norinori
Shade exactly two cells in each region. Every shaded cell must share an edge with exactly one other shaded cell, forming dominoes across the grid.
Try it now — Easy 8x8 →The Rules
- Shade exactly 2 cells in each region
- Every shaded cell must share an edge with exactly one other shaded cell — forming a domino pair
- Domino pairs may cross region borders
- No shaded cell can have more than one shaded neighbour
Available in 3 sizes (6x6, 8x8, 10x10) and 3 difficulty levels (easy, normal, hard).
See It in Action
Shade exactly 2 cells per region — every shaded cell must share an edge with exactly one other shaded cell
How to Play
- Identify regions where only one valid domino placement avoids adjacency violations
- Remember: dominoes can cross borders — one cell in region A can pair with a cell in region B
- Ensure each shaded cell has exactly one shaded neighbour — three-in-a-row is illegal
- Work outward from forced placements to resolve ambiguous regions
Pro Tips
Regions with only 2 cells automatically form a domino if those cells are adjacent — place them immediately
A shaded cell with only one valid unshaded neighbour must pair with that neighbour
Border-crossing dominoes satisfy two regions at once — use them to resolve difficult pairs of regions
Frequently Asked Questions
What is Norinori?
Norinori is a logic puzzle where you shade exactly 2 cells per region. Every shaded cell must be adjacent to exactly one other shaded cell, forming domino pairs that may cross region boundaries.
