Perfect Line: Draw & Solve

Perfect Line is a single mechanic, refined. Draw one continuous stroke with your finger from a start point to a goal, navigating around geometric obstacles along the way. Every stroke is scored against the mathematically optimal path — how efficient, how smooth, how precise you were. 100 handcrafted levels across 10 chapters, each introducing a new spatial idea: single detours, sharp corners, tight precision corridors, genuine route choices, multi-turn flow, and puzzles that combine them all. Perfect scores are rare. Reaching one means your stroke was efficient, smooth, and precise all at once — not luck, not slowness, just control. No accounts. No ads. No in-app purchases. No network connection of any kind — Perfect Line works completely offline, from the moment you install it. Your progress stays on your device. One line. No mistakes.
