How Scoring Works

📏 Side Equality

All four sides should be the same length. The closer they are, the higher this component scores.

📐 Angle Accuracy

Each corner should be exactly 90°. Deviation from right angles reduces your score.

📏 Straightness

Each side should be a perfectly straight line. Wobbles and curves between corners lower your score.

Tips for Drawing a Better Square

Pause at Corners

Briefly slow down or pause at each corner to create sharper 90° angles.

Use Your Whole Arm

Move from your shoulder for straighter lines instead of drawing with just your wrist.

Steady Speed

Maintain a consistent, moderate speed throughout each side of the square.

Close the Shape

Make sure your ending point connects back to where you started to complete the square.

Frequently Asked Questions

How is my square score calculated? +
Your score is based on three factors: side equality (are all four sides the same length?), angle accuracy (are all corners 90°?), and straightness (how straight are your lines?). These are combined with a power curve, so higher scores are exponentially harder to achieve.
Why can't I score above 99.9%? +
The maximum possible score is capped at 99.9% because a mathematically perfect freehand square is virtually impossible. Even tiny hand tremors create measurable deviations.
What makes drawing a square harder than a circle? +
Squares require four sharp 90° corners and perfectly straight lines — both are difficult freehand. Circles only need smooth continuous curvature, which is more natural for hand movement.
Does this work on mobile? +
Yes! Draw with your finger on any touchscreen device. The canvas adapts to your screen size automatically.
Any tips for a higher score? +
Pause briefly at each corner to create sharper angles. Draw at a steady, moderate speed and focus on making all four sides equal length. Practice drawing straight lines before attempting full squares.
