• ✓Bins in a horizontal row with a type glyph on the belly; the rubbish sits above them
• ✓Two ways to play in one code path: drag it down, or tap the piece then tap a bin
• ✓An item carries a MATERIAL, not a bin; each level maps materials onto the bins it shows
• ✓Level 1 is Bangkok's four bins, level 2 a school's finer row, level 3 every bin there is
• ✓The same bottle is ถังเหลือง on the street and ถังพลาสติก at school — that IS the lesson
• ✓A colour ↔ type reference card, openable mid-game from the ? button
• ✓A wrong bin costs nothing: it shakes, the piece goes home, and the nudge says which bin wanted it and why
• ✓Three misses in a row opens a breathing pause; Poppy hosts
• ✓The end card tallies the round by type, with percentages and the actual item list — not a mark out of ten
• ✓Replay re-deals AND re-scatters; a coarse shuffled grid with jitter keeps pieces from ever stacking
• ✓Repaint the bins as Kidsquare watercolour — the SVG ones are a stand-inplanned
• ✓All 32 pieces of rubbish are painted watercolour — no emoji stand-ins left
• ✓Add an infectious-waste level (masks, test kits) and where the local hazardous drop-off isplanned

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