Doodle Decoder

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.
