About this game

🧲 One simple rule, infinite variety
Every level gives you pairs of matching colors. Your job is to link each pair with a continuous line. The only condition: lines must remain independent. Touching or overlapping is not permitted.

⚡ Logic over speed
There is no clock. No rush. Each puzzle is a quiet conversation between you and the grid. Experiment with different orders. Undo freely. Restart when needed. The correct sequence always exists — you just have to find it.

📐 From open boards to tight mazes
Early stages offer plenty of room. Later, spaces shrink, colors multiply, and obstacles appear. You will learn to read the board differently — spotting bottlenecks, anticipating blockages, and leaving room for later connections.

🎨 Visual clarity, tactile response
Each color stands out clearly. Drawing feels fluid and responsive. Every successful match triggers a gentle confirmation, making progress satisfying without being distracting.

🧘 A calm mental workout
This is not about memory or reaction time. It is about observation, patience, and forward thinking. Each solved level leaves you sharper and more relaxed — a rare combination.
