Tap Start to play — spot the answer!
Keep going — this game grows with you
- L2 Understandsay what each piece means before you start
- L3 Applyuse counting and adding to reach the answer
- L4 Analyzetwo answers are close — show which step made them differ
- L5 Evaluatechoose the fastest correct method among three, and say why
- L6 Createwrite a problem whose answer is the number shown
Starts at L2 · climbs to L6 — analyze, evaluate and create, not just remember.

| Capability | TTC | Failure mode | Detection |
|---|---|---|---|
| node → complete PWA compile | 1000ms | LLM leaked or transform > 1s (LAW 0 breach) | measured compile ms > 1000 → RED |
| every challenge + option renders | 50ms | option dropped or not exactly one correct | options emitted == node AND one correct per challenge |
| offline play after first load | 50ms | precache drifts from files | targets ≡ PRECACHE ≡ disk |
| wrong tap costs a life; three ends run | 50ms | lives never decrement | livesLeft-- + gameOver at 0 |
| best streak survives reload | 50ms | localStorage throws and kills game | every localStorage touch in try/catch |
| tones via WebAudio | 50ms | AudioContext before gesture blocked | AudioContext only in start handler, try/catch |
