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 |
