順序記憶

Sequence Memory tests your ability to remember and reproduce a growing sequence of positions on a 3×3 grid — a visuospatial sequence-span task.

Tiles light up one by one. After the sequence ends, tap the tiles in the same order. Each correct level adds one step. Sequences are seeded deterministically per session.

Primary result is the longest sequence you reproduced correctly, plus total correct trials.

This is a research-grounded task (Evidence B/C). It is a benchmark of sequence span, not a clinical memory assessment.
