• ✓Idea: tidying is two skills — sorting into groups, and putting in order — so both live in one game
• ✓Six sorting rounds: animals/food/things · land–water–sky · alive–not alive, and more
• ✓Four ordering rounds: smallest→biggest and shortest→tallest
• ✓One gesture throughout: tap a thing, tap where it goes
• ✓Reuses the painted vocab tiles, with an emoji standing in where a tile is missing
• ✓A wrong box only shakes its head — the thing goes back to the pile, nothing is lost
• ✓Three misses buys a breath together, then the counter resets
• ✓Machine-checked: every round has exactly one right answer (npm run verify:sorting)
• ✓Two-rule rounds — colour AND kind at onceplanned
• ✓A gentle timed mode for older childrenplanned

✓ = done · ☐ = planned. Every game is built one step at a time like this.
