Ordered spatial recall
Watch cells light up one at a time on a 3×3 board, then select the same positions in the same order. Correct rounds lengthen the next sequence; an error ends the round and leaves the current level visible.
Recall a growing sequence after each visual cue has disappeared.
Start test
This task requires both position and order. It is different from the Visual Memory Test, which presents several locations simultaneously and does not require an order.
Level and accuracy describe performance in this implementation. They are not an IQ score, a memory diagnosis, or a standardized memory-span result.
A round generates a sequence of grid indexes and reveals them in order. Input opens only after the final cue. Selecting a wrong position, or a right position at the wrong step, counts as an incorrect attempt.
The starting level is three. A completed sequence raises the level for the next round; reset returns the level and counters to their initial state.
Accuracy is correct completed attempts divided by all completed attempts. A high level reached after very few attempts carries less context than several rounds at the same setup.
Keep the device, display size, sound, and interruption level stable when comparing sessions. Familiarity with the grid and cue rhythm can change results.
A browser sequence does not isolate working memory from visual encoding, motor input, strategy, or practice. It cannot assess a memory disorder or predict school or work performance.
Recent level, accuracy, and attempt summaries are stored in this browser. Clearing site data removes them; the task has no account or public leaderboard.

Repeat a four-pad color sequence that grows each round and review best length, mistakes, and average input delay.
Start
Test visual memory by recalling highlighted grid positions, then review accuracy, level, mistakes, and browser-only session history.
Start
Recall digit strings from 3 to 20 digits with adjustable display time, strict matching, spacing, and local best length.
