Alternating Trail: Connect a newly randomized node field by alternating numbers and letters in the sequence 1–A–2–B.

Memory & recallMeasures Memory & recall through speed, accuracy, control, awareness, and consistency signals.
How it works

How it works

Click the nodes in alternating number-letter order; one wrong node ends the trial. The test preserves timing, errors, misses, and control evidence across calibration, pressure, and consistency blocks.

Grades interpret the platform score; they are not fixed global percentiles. A global percentile appears only after the same version, platform, and input mode reach the valid-sample threshold.

How to train

Repeat short sequence recall sets with the same device settings. Stabilize accuracy first, then reduce response time without increasing misses.

Device and fairness

Refresh rate, browser scheduling, display size, and input latency can affect results. Compare scores within the same platform and input mode.
