About this game

Are you ready to test your intelligence and sharpen your mind? Welcome to One Line — the ultimate one-stroke drawing puzzle designed to challenge your brain and keep you entertained for hours!

Based on classical mathematical graph theory and Eulerian paths, the rule is simple yet deeply satisfying: Connect all the dots with just one single stroke, without lifting your finger and without retracing the same segment twice!

Whether you want to unwind after a busy day or kickstart your cognitive skills in the morning, OneLine is your perfect daily brain-training companion.

🧠 EASY TO LEARN, CHALLENGING TO MASTER
OneLine starts with simple, elegant shapes that teach you the core logic. But as you progress through different chapters, you will face complex symmetrical grids, intersecting lattices, sacred geometry, and mind-bending 3D perspective puzzles. Can you solve them all in one go?

🌟 CORE FEATURES YOU’LL LOVE:
• Endless Brain-Training Puzzles: A vast, ever-growing collection of mathematically solvable geometric shapes.
• Sleek Modern Design: A premium, minimalist interface featuring vibrant, hand-picked pastel backgrounds and beautiful vector graphics.
• Smart Interactive Hints: Stuck on a tricky level? Unlock real-time, looping gold guideline paths that show you the starting strokes, or use auto-skips to keep your momentum going!
• Zero Clutter & Distractions: Focus entirely on the lines with no redundant vertex beads, pen pointers, or messy interfaces.

✨ PROGRESSIVE THEMED CHAPTERS
Solve puzzles across beautiful thematic chapters, each featuring a unique color palette and geometric style:
1. Genesis: Perfect introductory shapes and soft pastel pinks.
2. Orbit: Orbital loops, double-diamonds, and soothing lavenders.
3. Labyrinth: Dense intersecting paths and golden sunset pastels.
4. Infinity: Symmetrical curves, endless loops, and vibrant terracottas.
