The one-stroke drawing test

Can you draw a perfect line?

It sounds simple, but drawing a perfectly straight line freehand is notoriously difficult. Without a ruler, your natural body mechanics will try to curve it.

  • No sign-up, no ads, no downloads — it runs right in your browser.
  • Works with mouse, trackpad, touch and stylus.
  • 78 shapes to master, from a simple circle to a spiral.
How to draw a line

The trick to drawing a straight line

Because our arms move in arcs around our joints, drawing a straight line requires you to compensate for that natural curve as you move.

  • Lock your wrist and elbow; move entirely from your shoulder.
  • Look at your destination point, not the tip of your pen or cursor.
  • Draw with a single, fast, confident stroke. Speed is your friend here.
  • Avoid 'hairy' lines where you sketch slowly; commit to one motion.
  • The orientation doesn't matter—horizontal, vertical, or diagonal—just make it straight.
How it works

Three steps to your score

There is nothing to learn. Choose, draw, and read your result — the whole loop takes about five seconds.

  • Pick a shape from the bar at the bottom of the screen.
  • Press and draw it in one stroke, anywhere you like.
  • Release to see your accuracy score and the ideal overlay.

The perfect Line drawing game

A Line drawing game that actually relaxes you

This is the drawing game to open when you need a moment away from everything else. Sketch the Line 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.

  • Perfect coffee-break game — a single Line attempt takes five seconds flat.
  • Quiet focus training: one hand, one line, one honest score.
  • Beats a phone-scroll spiral — draw a Line, breathe, feel a bit less wired.
  • Kids love the Line challenge; grown-ups love that it never gets easier.
  • No ads, no sign-up, no downloads — open a tab and play the Line game.
Live colour feedback

Feel your accuracy as you draw

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.

Honest, calibrated scoring

How your score is calculated

Your stroke and the perfect line 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.

  • Draw at any size, anywhere — scale and position never count against you.
  • A clean freehand attempt lands near 89%. 98%+ is close to machine-perfect.
  • Letters and numbers stay orientation-locked, so a rotated 6 is never a 9.

Advanced control

Mastering corners and curves on the line

Drawing a complex shape like a line in one stroke requires you to plan ahead. You have to maintain your flow while executing tight turns, without lifting the pen once.

  • Start your stroke at a natural anchor point, like a top corner or edge.
  • Cross the shape confidently when required, keeping your hand steady.
  • Focus on the symmetry; the angles should match as you return to the start.
  • A perfect line has flawless proportions.
  • Try it in Easy mode first, then switch to Hard for a real test of your aim.

Your call

Easy, Normal or Hard

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.

Frequently asked questions

Why is this the hardest 'easy' shape?
Your arm is essentially a pendulum. Unless you move your entire body alongside your hand, the pen naturally wants to travel in an arc.
Does the length of the line matter?
No, the scorer resamples the line regardless of size. However, drawing a very short line is often easier to keep straight than a long one across the whole screen.
