Reverse Sequence

In Reverse Sequence, memory is only the starting point, and the real challenge lies in reverse reconstruction. On the screen, the numbers will light up in turn-for example, 4 → 1 → 7 → 3. Your task is not to reproduce this order, but to click backwards from end to end after they disappear: 3 → 7 → 1 → 4.
This is far more than a simple memory, but a deep test of working memory, cognitive flexibility and inhibition control ability. The brain is naturally inclined to output in the original order, and Reverse Sequence requires you to actively suppress this inertia and accurately "flip" the whole sequence in your mind. One wrong step and start all over again.
