Memory sports,
online and on demand.

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.

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.
