How do you draw a perfect square in this game?

Trace all four sides of the ghost square in one continuous stroke, keeping the lines straight and the corners at sharp 90-degree angles, then close back to your start. Slowing down at the corners is the key to a high score.

Why is a perfect square hard to draw freehand?

Your hand naturally wants to curve, so drawing four truly straight sides with sharp 90-degree corners is surprisingly hard. That is exactly what the perfect square test measures.

What is a good perfect square score?

Most players score between 70% and 85%. Anything above 90% is excellent and leaderboard-worthy, since straight lines and crisp corners are tough to hit freehand.

Is the Perfect Square game free to play?

Yes. Draw a Perfect Square is completely free, runs in any modern browser, and needs no download, sign-up, or install.

Can I play the Perfect Square game on mobile?

Yes. Draw with your finger on phones and tablets, or use a mouse or trackpad on desktop.

Precision drawing

Draw a perfect square — corners, not curves

Four sides, one stroke. The ghost square is a guide; the score is whether your path is actually square.

Hands want to round corners. This game exists to measure that habit, not to host another generic shape quiz.

How we score a square

We fit a rotated square to your stroke (Chebyshev geometry): center, side length, and orientation all come from the path you drew, not from a locked template in screen space.

Score then falls when sides bow, corners soften, or one edge is longer than the others. A tilted but even square can still rank well. A rounded blob that happens to sit on the ghost cannot.

How to play

Press and hold, trace all four sides without lifting, and close back to the start. Release to lock the score.

Slow down at each corner. Rushing a 90° turn is the usual way a 90% becomes a 75%.
