— The tests —
Trail Making — Variant A
Connect the numbers 1–25 in order as fast as you can. Measures visual attention and processing speed.
PlayTrail Making — Variant B
Connect numbers and letters alternately — 1→A→2→B… Same speed race as Variant A, but now your brain switches tracks on every tap.
PlayDual N-Back
Squares flash and letters are spoken. Flag it whenever either one matches what came N steps back — a serious working-memory workout.
PlayCorsi Block-Tapping
Watch the blocks light up one by one, then tap them back in the same order. Measures visual-spatial memory.
PlayCorsi Block-Tapping — Backward
Same as Corsi, but tap the blocks back in reverse — last one first. Now you're holding the whole run in mind and flipping it.
PlayRemote Associates Test
Three unrelated words, one word that links all three — find it. A classic test of associative thinking and that click-into-place "aha".
Memory Palace
Learn the ancient memory-palace trick: pin each item to a spot along a route you know by heart, then walk it back to recall them in order.

Juggle a growing list while a second task keeps butting in — and see how much your working memory can really hold at once.
