A new memory sport for learning sentences and texts
Meta Memory Sports is a new form of memory sport created by Orissam, a specialist in memory-based learning. Its defining feature is that it improves on several limitations of traditional memory sports and is designed to provide direct support for real-world learning.

PreviewImagery 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.
Memory sports training methods
Memory sports are the best way to train your short-, medium-, and long-term memory all at once. In Custom mode, freely adjust the memorize time and recall time to focus your practice on whichever kind of memory you want.
- Working memory (short-term) — Keep both the memorize time and recall time short. Builds the ability to bring back what you just saw instantly.
- Medium-term memory — Short memorize time, long recall time. Practice holding onto information even after a little time has passed.
- Long-term memory — Keep both the memorize time and recall time long. Trains the deep storage that makes memories last.
Within a single session — Split a session into segments and mix several memory techniques. Since the information you memorize first is usually the first to fade, etch it in firmly early on with long-lasting methods (memory palace, spaced repetition), lean on imagery through the middle, and skim quickly at the end to hold the rest in working memory.
Hands-on techniques like the memory palace and spaced repetition are covered step by step in the learning guides. Browse the guides
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 |
|---|---|---|
| 2.0+ | About 2× the global average (with 20-play / 60s gate) | |
| 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 |

Memory sports FAQ
- Memory sports are mental disciplines where you memorise numbers, words, cards, images, and more within a set time limit and recall them precisely. WMSC (World Memory Sports Council) and IAM (International Association of Memory) maintain the international standards; in Korea, KMSL runs the national competitions.
- 11 events in total: numbers, binary, cards, spoken numbers, images, abstract images, names, words, dates, sentences, and tables (book TOC). Nine are playable directly from the home page; sentences and tables are meta events under the Meta tab.
- Seven grades — SS · S · A · B · C · D · F — calculated from the last 30 days using plays (50%) + average score (25%) + average memorisation time (25%). Promotions apply immediately; demotions apply once per day at 23:00 UTC.
- The two modes follow the same big-picture idea, but the penalty math differs by event. Standard scoring is a flat +1 per correct cell across every event, with wrong answers simply scoring 0 and no further penalty. Strict scoring applies the WMSC competition format per event: numbers, binary, and words are scored row by row (40 digits, 30 digits, and 20 items per row respectively) — one wrong answer in a row halves that row's score, and two or more wipe the whole row to 0. Cards and spoken numbers freeze the score at the first wrong answer or blank cell, and anything correct after that point is no longer counted. Images and abstract images are scored in groups of 5; any wrong or blank cell in a group turns that group into -1 (a group that is entirely blank scores 0). Historical dates and sentences ignore blanks and deduct -1 for every two wrong answers. Names & Faces and Table of Contents have a single scoring rule, so the toggle is hidden. Speed mode is locked to standard scoring, except Binary, which uses strict 30-digit row scoring to prevent random-input advantage. Custom mode still lets you choose the scoring method.
- Use the [Multi] button on a home card to create a room, or join from the “Open rooms” list in the sidebar. Free members can play with up to 5; membership tiers raise the cap to 11 / 21 / 31.
- You can delete your own results within 7 days from the [My results] page. Older results are already factored into grade statistics and can no longer be removed.
- Tap the [Print] button on any event card to open a sheet you can save as PDF/PNG or print directly — useful for recall practice on paper. (Spoken numbers is audio-only and not printable.)

One conversion practice, now available in class.
Basic recall is now the forward self-check default, alongside typing, reverse recall and rhythm, with earlier records retained. Classes practise the same selection using the teacher’s shared dictionary or a student’s own source. Private entries and typed answers stay hidden; teachers see progress and summaries. Class practice stays separate from personal review dates and official rankings.

Less waiting when image memorization starts.
Solo, multiplayer and classroom image screens are prepared during the countdown, so a ready screen no longer spends memorization time waiting for start-up requests. Rejoining preserves the original round’s remaining time.
2026-10-20
Prepare the images, then start together.
Solo preparation countdowns begin after the images are ready. Multiplayer and classes show participant readiness and start together when everyone is ready. Teachers see each student’s status; their existing memorization-start choice needs no second readiness-confirm click.
2026-10-19
Review classroom answers and activity history more clearly.
Image activities now support up to 300 images. Each discipline places correct answers above student entries, and version 0 notes hide the duplicate original view. Activity history separates viewing results from repeating content; quantity errors identify the selected discipline’s limit, digit-group rule, and current entry.
