Rule Flip: sort by Rule A (color) → silent flip to Rule B (size) → adapt → replay. No quiz screen bolted on. Built for curious kids who want another round.
Honest status: Pack + HTML demo ready. Kid playtest held (Nick behind Etsy). Demo is a prototype — not an App Store product.
“Learn by adapting — not by answering a quiz.”
Prototype HTML · ages 6–8 fence this test · Partner Nick (after Etsy)
Hard pass only when a kid induces Rule A uncoached, adapts after the silent flip, and starts a second full round with zero adult prompting.
Color → size without announcing the change. Adaptation is the proof.
Rule induction / flexible categorization — not a quiz after a game.
Single-screen playtest. App Store / accounts / progress tracking out of fence.
Facts from the venture pack — not marketing fluff.
Pack + demo ready → kid playtest. Continue/kill after hard pass/fail.
Demo lives on the portfolio status board. No App Store push this phase.
