Brain Training Games
A collection of brain games that challenge your memory, focus, and reaction speed. Track your scores and compare with others.
Imagery training
Memory sports come down to turning abstract data (digits, letters, binary) into vivid images you can store in long-term memory. A pre-trained imagery table lets the same number trigger a much richer scene every time.
- Shape conversion — Turn the shape of a digit or card into an object that looks like it.
- Sound conversion — Map the pronunciation of a digit or card to a similar-sounding word.
- Major system — Assign consonant sounds per digit, then build words and visualise them.
- PAO system — Pair each digit/card with a person, action, and object to build scenes.
- Memory palace — Lay images along a familiar route to preserve their order.
Imagery training material is available in the Metamind learning notes. Build your own conversion tables and drill them into automatic recall — that's the fastest path.
Overall grade guide
Your overall score is calculated from the last 30 days. Demotions apply once a day at 23:00 UTC, while promotions take effect immediately when a game ends.
Total weighting: Plays 50% / Average score 25% / Average memorisation time 25%. Average score is normalised across the 11 events.
- Plays — counted linearly from 20+; below that it's capped at 1.499.
- Average score — weighted across the 11 events (same weights as the original site).
- Average memorisation time — counted linearly from 60s+; shorter is better.
| Grade | Total threshold | Basis |
|---|---|---|
| SS | 2.0+ | About 2× the global average (with 20-play / 60s gate) |
| S | 1.5+ | About 1.5× the global average (with 20-play / 60s gate) |
| A | 1.1+ | Slightly above the global average |
| B | 0.9+ | Near the global average |
| C | 0.7+ | 70% of the global average |
| D | 0.5+ | 50% of the global average |
| F | 0.5- | Entry level |

New brain game: N-Back
N-Back is here to challenge your position memory — cells light up one at a time, and you decide whether the spot that just lit matches the one 2 steps back. Log in to save and compare your scores.

New brain games: Number, Sequence, Visual & Verbal Memory, and the Chimp Test
Five new memory games are here — Number Memory (type back the number you saw), Sequence Memory (tap the tiles in the order they lit up), Visual Memory (find every cell that lit up), Verbal Memory (tell seen words from new ones), and the Chimp Test (tap the hidden numbers in order). They get longer and harder the better you do, and you can log in to save and compare your scores.
