The spiral is an endurance test. You must maintain a constantly increasing radius while keeping the spacing between the loops perfectly even.
A perfect spiral (or Archimedean spiral) grows outward at a constant rate. The trick is to keep your eye on the gap between the line you're drawing and the previous loop.
There is nothing to learn. Choose, draw, and read your result — the whole loop takes about five seconds.
This is the drawing game to open when you need a moment away from everything else. Sketch the Spiral in one confident stroke and watch the score tell you the truth — no filters, no fake celebration. It's short enough to fit in a five-second break and honest enough that you'll want another go.
Your trail colours itself in real time — green where you are dead on, amber where you drift, red where you are well off. You never have to wait for the final number to know how you are doing.
Your stroke and the perfect spiral are both resampled into evenly spaced points, then the ideal is fitted onto your drawing. Your score is how far your line sits from that best possible fit.
Drawing a complex shape like a spiral in one stroke requires you to plan ahead. You have to maintain your flow while executing tight turns, without lifting the pen once.
The best-known competitor offers four shapes. This offers seventy-eight — and every one of them is drawable in a single stroke.
Every shape here is built to be drawn in one stroke, so learning one is learning them all: pick it, trace it, and read your accuracy. Circle, star, square, triangle, heart, straight line and dozens more.
This is the same honest challenge with live colour feedback, an ideal-shape overlay, three difficulty modes and 78 shapes to beat — not just one lonely spiral.
Change how strictly the same stroke is judged. Easy is forgiving enough for small hands; Hard demands near-machine precision. Personal bests and leaderboards are kept separately for each mode, so an Easy 99% never sits on a Normal board.
One simple idea that works for very different people.
Scroll back up to the canvas, press down, and draw it in one stroke. It only takes a few seconds to find out how steady your hand really is.
Pick a shape from the bar below, then draw it freehand in one stroke anywhere on the screen. A very faint outline hints at the target. Release to see how close to perfect you got.
