About
Looking for a puzzle that calms you down while your brain lights up? Place one happy pup in every color, and let pure logic do the rest.
HOW IT WORKS - THREE TINY RULES
- One dog per color region
- One dog per row and per column
- Dogs never touch - not even diagonally
Sounds simple. Feels like magic when the whole board clicks into place.
