Rank shows how far you have walked. Titles show how well. Tap an earned title to wear it.

A seeded 6x6 park that is the same for everyone today. Keep the streak alive.

• 🐶 One per park. Every coloured park holds exactly one dog.
• ↔️ One per line. Exactly one dog in every row and every column.
• 🚧 Personal space. No two dogs may touch, not even at a corner.
• 👆 Fences. Tap a square for a fence ❌. Hold and drag to fence a whole run at once, and drag starting from a fence to rub them out again. Fences are just your notes.
• 🐶 Dogs. Tap twice on a square (or right click) to place a dog. Dogs are final: a right one locks in, a wrong one costs a life.
• ⛓️ Always solvable. The 4×4 teaching parks start with one dog placed; larger parks start empty. Every board can be finished by pure logic with no guessing.

Learn by playing a real park. Takes about a minute.
