Draw the prompt on a paper canvas while a transparent feature checklist lights up region by region, and tells you what you still haven't drawn.

How to play
You're given something to draw. As your ink covers each feature zone of the page, the recognizer ticks that feature off. Cover every required feature and the prompt is recognized.
Sketch the named subject with the pointer; each feature lives in its own zone of the canvas.
Watch the checklist and confidence meter rise as features register.
Optionally hide the helper zones for a cleaner challenge.
Recognize the prompt in fewer strokes and less time to score higher.
Controls
Desktop: draw with the mouse; click Undo, Clear, New prompt, and the zone/mode toggles.
Phone & tablet: draw with your finger, full touch and stylus support.
Game modes
Daily picks a deterministic prompt from the date; Practice rolls a fresh random one.
Tips & strategy
Read the checklist for what's missing instead of over-rendering one part.
Place each feature in its expected zone of the page, that's what the recognizer is checking.
What you'll learn
Doodle Decoder turns guided sketching into a feature-by-feature recognition game that teaches what makes a drawing read.
For parents & teachers: learn to draw by recognizing features.
Origins
Drawing until a recogniser has ticked off every required feature is machine recognition used as a drawing prompt.
Grading by feature zones rather than by likeness is the original method.
That is closer to how recognition works and to how drawing is taught. A recognisable sketch is a set of diagnostic features rather than an accurate picture, which is why a few lines can read as a bicycle and a careful rendering can fail to.
