Watch the growing sequence and repeat it in the same order. Track your best level and your trend over time.
Working memory is a short-term mental workspace. It helps you follow instructions, keep track of steps, and update information while you act. In this test, your main metric is the highest level reached in a run.
Because each level adds one step, small improvements can be meaningful. Rather than chasing one lucky run, look at your trend across multiple sessions on the same device.
No. This is a simple cognitive task for self-tracking and comparison. It is not a medical tool and does not diagnose any condition.
Working memory is sensitive to sleep, stress, attention, and distractions. Look at several sessions to estimate your baseline.
It adds interference: you must remember only the target tile and ignore the distractor. That increases selective-attention demands while keeping the same response rule.
