Draw it with a loop. A pen goes forward, turns, and repeats — and out comes a square, a star, a spiral, a flower. Read the little program (a for-loop, a turn, a growing length), predict the picture it draws, then watch the pen make it. The Logo turtle, re-imagined as a read-before-you-run puzzle — the clearest way to SEE what a loop does. A draw-with-code lab. Ages 9–14.
▶ Play it nowBuilt for sittings of about 20 minutes on the screen. That is our design budget, not a measurement.

Meet the cast
DoodleForge's pen pals each draw with one idea: repeat, turn and grow.
Wonky
(The one you teach) - picks a turn by feel and the shape won't close — you teach the full turn
Rosette
draws a shape again and again, turning a little each time
Curlicue
lets each side grow a little longer, into a spiral
Penwick
counts the sides and keeps the pen on the page
