SEQUENCE SPAN
Working Memory
L1 · Remember
Item format modelled on span tasks — a sequence that grows and must be reproduced in REVERSE order (backward span).
Watch the pattern light up — then tap it back BACKWARDS. Every round adds one!

Watch the pattern, then tap it back BACKWARDS!
Keep going — this game grows with you
- L1 Rememberwatch the pattern and tap it back in REVERSE order
- L3 Applytry a short 2-step pattern backwards first
- L4 Analyzeafter a run, notice which shape repeated most — find the pattern inside the pattern
- L5 Evaluatetwo chunking strategies work — pick the one that helped you remember more and say why
- L6 Createinvent your own 5-shape pattern, play it back backwards, and teach it to someone
Starts at L1 · climbs to L6 — analyze, evaluate and create, not just remember.
TTCF — capability · time bar · failure mode · detection
| Capability | TTC | Failure mode | Detection |
|---|---|---|---|
| node → complete PWA compile | 1000ms | LLM leaked or transform > 1s (LAW 0 breach) | measured compile ms > 1000 → RED |
| all pads render from the pad set | 50ms | a pad is dropped — the sequence can reference a missing pad | pads emitted == node pads |
| offline play after first load | 50ms | precache drifts from files | targets ≡ PRECACHE ≡ disk |
| the pattern grows and a correct BACKWARD tap-back advances the round | 50ms | direction silently reverts to forward — the game still looks right, still advances, and is measuring the wrong construct | emitted comparison indexes seq from the END (seq.length-1-step) and the node's recall= is echoed in the compiled source |
| deepest-round best survives reload | 50ms | localStorage throws and kills the game | every localStorage touch in try/catch |
| pad tones via WebAudio | 50ms | AudioContext before gesture blocked | AudioContext only in a gesture handler, try/catch |
| the game shares no name, palette or mechanic with a third-party product | 50ms | a rename lands but the pads and direction do not, leaving the exposure exactly where it was | no pad colour in the red/green/blue/yellow set · pad count != 4 · recall=backward · zero occurrences of the retired name in any emitted file |
