Brain & Memory Tests
The classic cognitive benchmarks, playable in seconds: digit span (how long a number can you hold?), visual and sequence memory grids that keep growing, verbal memory with an ever-longer word list, the famous chimp working-memory test, the Stroop colour-word test and a reading-speed measure with an RSVP speed-reader built in.
Each test is faithful to the psychology-lab original, so your scores are comparable session to session — and they save locally, so beating last week’s digit span becomes a genuine habit. Most people find one test they are unexpectedly good at and one that is humbling; the chimp test is usually the humbling one.
Chimp Test
Click the numbers in order from memory — the famous chimp working-memory test.
Number Memory
Remember the number as it gets one digit longer each round. What is your level?
Visual Memory
Remember which tiles flashed, then click them back. It keeps growing.
Stroop Test
Name the ink color, not the word. A classic test of focus and reaction.
Reading Speed — WPM
Measure your reading speed in words per minute, plus an RSVP speed-reader.
Sequence Memory
Repeat the growing sequence of tiles. How long can you go?
Verbal Memory
Seen this word before? Keep a growing list in your head. Surprisingly hard.
Brain & Memory Games — frequently asked questions
Yes — your best scores and streaks are stored in your browser on your device, ready when you come back. Nothing is uploaded, and most tests give you a shareable result to challenge friends.
They are faithful versions of established cognitive tasks — digit span, the Stroop effect, the chimp working-memory test. They genuinely measure those specific abilities, though they are for fun and self-tracking, not clinical assessment.
Yes — working-memory span, Stroop speed and reading speed all improve noticeably with regular attempts, which is exactly what the locally saved history lets you watch happen.
