How to play
Choose a memory load, watch the target or targets, inspect the connected field, answer once, and use the exact reveal before moving on.
1. Choose Baseline or Advanced
Baseline shows one target and asks whether that complete target is hidden in the field. Advanced shows Target A and then Target B. Answer Yes in Advanced only when both complete targets occur in the field. Extra lines may attach to target vertices; the target does not need to appear as an isolated object.
2. Choose an exposure
Each target is visible for 0.8, 1.5, or 2.5 seconds. The setting controls presentation time only. It never changes the gold answer or score. Begin at 2.5 seconds, reduce the time after the rule feels familiar, and avoid treating speed as a measure of ability.
3. Inspect, answer, and read the reveal
When the larger field appears, select Yes or No. Correct answers add one point. A false positive is a Yes response when the required target was absent. A false negative is a No response when it was present. The reveal draws the true position in coral for Target A and sage for Target B. An absent target is labeled absent rather than highlighted on a near-match.
4. Finish ten rounds and replay
A session always contains ten rounds. The result summarizes correct, false-positive, and false-negative counts. Replay shuffled set draws a new order from the same validated forty-card pool. Change settings returns to the start. The five most recent summaries remain only in this browser.
