About One Line Draw
One Line Draw is the timeless 'draw it without lifting your finger' puzzle, dressed up in calm neon. Each level hands you a constellation of glowing dots joined by faint lines, and your job is to light up every single line in one unbroken stroke, never tracing the same line twice. On a triangle it looks effortless. On the star, the house, and the envelope it turns into a proper head-scratcher. Under the hood it's a lovely bit of graph theory, since only certain starting dots can possibly work, and the game quietly helps out by making those valid starting points pulse. Nothing punishes you for experimenting either. There's no timer, so you can undo a step, retry the level, or tap Hint to reveal a next move when you're stuck. With smooth glowing trails and that satisfying snap as the last line connects, it's a perfect bite-sized brain-teaser for a quiet moment.

How to play One Line Draw
Start on one of the pulsing (glowing) dots, then drag through connected dots to light up the lines between them. Every line must be traced exactly once, and you can never go over a line you've already drawn. Cover all the lines in one continuous stroke to complete the level. Use Undo to take back a step, Hint to highlight a possible next line, Retry to restart, or Skip to jump ahead.
Controls
Press a glowing dot and drag through connected dots to trace lines (mouse or touch). Buttons: Undo, Hint, Retry, Skip.
Tips & tricks
- Begin on a pulsing dot — only certain start points can finish the whole shape.
- If a shape has two 'odd' corners, you must start on one of them and finish on the other.
- Plan a route that saves dead-end lines for last.
- Stuck? Undo back a few steps and try a different branch instead of restarting.
