⚡ A puzzle with one unbreakable law
On your screen sits a field of scattered markers. Each marker has a twin of the same shade. Your mission: trace a line from every marker to its other half. The law? No two trails may touch, not even once.
🧭 Choose your order wisely
Every stroke changes what remains possible. Draw one line too early, and you might box yourself in. Draw it too late, and the space disappears. You are not just drawing — you are orchestrating a sequence.
🏗️ From wide-open spaces to tight corridors
The first few boards are spacious and forgiving. Soon, the playing field becomes denser. More twins appear. Pathways shrink. You will learn to spot dead ends before you reach them — and leave breathing room for the final strokes.
👆 Fluid drawing, instant feedback
Trace with your finger and watch the trail follow smoothly. Every successful completion gives a quiet nod — a small vibration, a subtle glow. Nothing flashy, just enough to tell you "that one is done."
🧘 No timers, no penalties
Take all the time you want. Change your mind? Undo. Hit a dead end? Restart the whole board. There is no punishment for trying — only the satisfaction of finding the one arrangement that works.
