Master AI prompting in 10 stages — from absolute beginner to expert
W A S D to walk · Shift to run (or just keep holding — you'll break into a run) · Space to jump · drag the mouse to look around.
Joystick (right) to walk — keep holding and you break into a run · JUMP button to hop · touch & drag to look · pinch to zoom.
Walk up to a stage hut to start a prompt challenge. A friendly wizard guides you step-by-step, then real AI scores your prompt and coaches you. 75%+ unlocks the next stage.
Half the stages are adventures: row a boat to a lake island, bounce a mushroom onto a sky platform, climb a mesa and a treetop, and scale Sigiriya Rock for the finale. Follow the green beacon.
Each animal teaches a prompting framework — AIM, the 5 C's, Chain-of-Thought and more. Pass their Quick Check quiz to earn bonus ⚡.
Gather 40 sparks scattered across the island, and hunt down the hidden treasures — chests, a secret cocoon, and the golden lion atop Sigiriya.
Kick a ball into the goal, bounce on mushrooms, chase the chickens, warm up by the campfire, and zipline down from the summit. Tap 👤 to customise your character.
Complete stages in order — each one unlocks the next. Stage 1 is so easy anyone can do it; by Stage 10 you'll be prompting like a pro. Your progress saves automatically.
