About One Stroke
One Stroke is a classic one-line drawing puzzle with a glowing neon look. Each level shows a shape made of dots and lines. Start from any dot and drag to trace every line in one continuous stroke, without going over the same line twice. When the last line lights up, the puzzle is solved.
Early drawings are easy warm-ups, but the shapes soon become clever little mazes where the starting point matters. Here is the secret: if two dots have an odd number of lines, start at one of them and you will finish at the other. Levels are generated endlessly, always solvable, and grouped into colorful themed worlds: Mint Lagoon, Sunset Ink, Neon City, Aurora Sky and Ember Peaks. Undo and restart are always there, three hints help when you are stuck, and a Daily Challenge brings a fresh puzzle every day.
