How to play Perfect Shapes Gauntlet
Drawing a perfect circle is one test of a steady hand. This is five. The gauntlet asks you for the shapes every child learns first, and then measures them with a precision no teacher ever could. Each shape is drawn in a single stroke, then a dashed outline of the ideal shape appears over your line, and every part of your stroke is coloured from green (spot on) to red (way off) so you can see exactly where you went wrong.
- Press Start and read the prompt at the top of the canvas.
- Draw the shape in one continuous stroke with your mouse, finger or stylus. Any size, any position.
- For the square, triangle, star and heart, finish where you started to close the outline.
- For the spiral, start in the middle (or the outside) and wind round at least twice.
- Check your score, press Next shape, and repeat until all five are done.
- See your grade, compare the five shapes side by side and share your result.
The five shapes, and how to nail each one
- Square. The game expects four equal sides and four right angles. Most people make their squares slightly too wide. Pause for a split second at each corner so the corners stay sharp.
- Triangle. An equilateral triangle has three equal sides and 60° angles. Start at the top point, go down-right, across, and back up: imagining a clock face (12, 4 and 8 o'clock) helps place the corners.
- Star. Draw the outline of a five-pointed star, not the crossing pentagram. Keep the inner corners at the same depth and the five tips evenly spaced; the tips are where most points are lost.
- Heart. Two round bumps that meet in a dip, then curve down to a sharp point. Make both halves mirror images and do not let the bottom point drift to one side.
- Spiral. The ideal is an Archimedean spiral, where every loop is the same distance from the last. Keep your speed constant and widen the loop by the same amount each turn.
Why shape accuracy is a real skill
Every drawing is built from simple shapes. Artists block out a figure with boxes and triangles, designers sketch icons from circles and squares, and calligraphers practise spirals and loops to warm up their hands. Being able to put a clean shape down on the first try saves time and makes sketches look confident. The gauntlet trains three things at once: proportion (equal sides and symmetry), control of corners (sharp changes of direction) and control of curves (smooth, even arcs). Because the game measures each shape objectively, you quickly learn which of the three is your weak spot.
How the scoring stays fair: before comparing anything, your drawing is moved, scaled and rotated to line up as well as possible with the ideal shape, and the game tries every possible starting point and both drawing directions. That means you are never punished for drawing small, drawing clockwise or starting at a different corner, only for the shape itself being off.
A good routine is to play one full gauntlet as a warm-up before you sketch, note which shape scored lowest, and give that one extra attention next time. Players who repeat the run a few times usually see their weakest shape climb by ten points or more, because the colour-coded feedback shows precisely which corner or curve needs work.

Perfect Shapes Gauntlet FAQ
How are the shapes scored?
Each closed shape is compared with its ideal form after the game finds the best position, size, rotation and starting point for your drawing. The average distance between your line and the ideal outline, relative to the size of your shape, becomes your percentage. The spiral is checked against an evenly spaced (Archimedean) spiral around the best-fitting centre.
Does the size or rotation of my shape matter?
No. Big or small, tilted or upright, a square is judged only on how square it is. The one exception is the heart, which may only lean a little, because an upside-down heart is not really a heart.
What do the grades S, A, B, C, D and F mean?
Your grade is based on the average of all five shapes: S is 92% or more, A is 85% or more, B is 75% or more, C is 65% or more, D is 50% or more and anything lower is an F. An S grade takes a very steady hand.
What happens if I make a mistake?
If a shape is not closed, too small or a spiral has fewer than two turns, the attempt does not count and you can simply draw it again. Once a shape is scored it is locked in, so take your time before you start each stroke.
Can I play on a phone or tablet?
Yes. Draw with your finger or a stylus on a phone or tablet, or use a mouse, trackpad or pen tablet on a computer. The canvas fills the screen so you have room for a good-sized shape.
Is my best result saved?
