Recall
The classic memory match, redrawn in ink. Flip the cards, find all six pairs, then meet the 2,000-year-old trick your brain just used to win.
Flip the cards two at a time and find all six matching pairs. The fewer flips, the sharper your memory, try to beat your own record.

It's the whole basis of the “memory palace” (the method of loci): picture what you want to recall placed around a familiar space, and it sticks. Memory-competition champions aren't born with better memories, brain scans show they simply train this spatial strategy, and doing so measurably rewires the memory networks of ordinary people too.
The six you just matched, fall down any of these:
