Memory Forge

Train your memory with number and symbol cards, the chimp test, pairs, n-back and sequences — 30 levels, timed or untimed, or your own settings.

1. Choose a memory game

Each game trains a different kind of memory. Card games train short-term memory for order; the chimp test and sequences train visual–spatial memory; n-back trains working memory; the word list is where you practise memory techniques.

2. Pick a level or set it up yourself

Clock:

Pick any level — every level is open, so you can carry on where you left off on another device. Stars show how you did: ★ 70% · ★★ 90% (passed) · ★★★ perfect. Timed and untimed stars are kept separately.

Memory techniques that work

World memory champions are not born with special memories — they use techniques like these. In one study, ordinary people who practised the memory palace for about 30 minutes a day for six weeks more than doubled how many words they could remember, and kept most of the gain four months later (Dresler et al., Neuron, 2017). Pick one technique, practise it with the 📝 Word list game or the trainers below, then add the next.

Ways to remember things

🧩 Chunking

Group items into small blocks. “7 4 1 9 2 6” is six things; “741 · 926” is two. Most people can hold about four chunks at once, so bigger chunks mean more items. Phone numbers, card numbers and postcodes are already chunked for this reason.

🏛️ Memory palace (method of loci)

The strongest general technique. Pick a place you know well — your home — and a fixed route through it: front door, doormat, hall mirror, sofa… Put one vivid image of each item on each spot, then walk the route again to recall.

  • Start with 10 spots in one room or house; add more palaces later (school, work, a street).
  • Make each image interact with its spot: the banana is squashed in the door, the dog is licking the mirror.
  • One or two items per spot. Keep the route in the same direction every time.
  • Wait a day before reusing a palace for new things, so old images fade.

🎭 Story (link) method

Link each item to the next in a strange, moving little story: a ★ star falls on a ● ball that rolls into a ▲ tent… Great for short lists when you have no palace ready. Its weakness: if one link breaks, the rest of the story can go with it.

🖐️ Peg systems

Learn a fixed picture for each number once, then hook new items onto the pegs — useful when you need “what was number 7?”.

Rhyme pegs: 1 bun · 2 shoe · 3 tree · 4 door · 5 hive · 6 sticks · 7 heaven · 8 gate · 9 line · 10 hen.
Shape pegs: 1 candle · 2 swan · 3 handcuffs · 4 sailboat · 5 hook · 6 golf club · 7 cliff · 8 snowman · 9 balloon on a string · 10 bat and ball.

To remember “milk” as item 5, picture bees in a hive pouring milk.

🔤 Major system for numbers

Turn digits into consonant sounds, then add vowels to make words you can picture: 32 = M-N = “moon”, 94 = B-R = “bear”. Vowels and the letters w, h, y don't count; go by sound, not spelling (“knife” = N-F = 28).

Memory hooks: t has 1 down-stroke, n 2, m 3; four ends in r; L is the Roman 50; a mirrored J looks like 6; a K is two 7s; a cursive f looks like 8; P is a mirrored 9; zero starts with z. Major system trainer ↓

🧑‍🎤 PAO and the Dominic system

For long numbers and playing cards. Give every two-digit number a Person, an Action and an Object (07 = James Bond · shooting · a tuxedo). Six digits then become one scene: the person from the first pair doing the action of the second pair with the object of the third. The Dominic system finds the people by turning digits into letters (1 = A, 2 = B … 9 = N, 0 = O), so 15 = A.E. = Albert Einstein. Build it slowly: 10 new people a day.

👋 Names and faces
  1. Really listen, then say the name back: “Nice to meet you, Maya.”
  2. Pick one feature of the face (curly hair, big smile).
  3. Turn the name into a picture (Maya → a mayor's chain) and fix it to that feature.
  4. Use the name once more before you leave, and review new names that evening.
🌍 Keyword method for languages

Find an English word that sounds like the foreign word and link it to the meaning in one image. Spanish pato (duck) sounds like “pot” → a duck sitting in a cooking pot. Swahili kitabu (book) → a cat reading a book. Then say the real word aloud a few times.

🔠 Acronyms and first-letter sentences

Make a word or sentence from first letters: ROY G BIV for the rainbow, “My Very Educated Mother Just Served Us Nachos” for the planets. Best for short, fixed lists you need in order.

✨ Make images that stick

Plain pictures fade. Make them big or tiny, moving, colourful, loud, smelly, funny or a little absurd, and put yourself in the scene. Link items by action (the cat kicks the drum) rather than just placing them side by side.

Learn so it lasts

🧪 Test yourself (retrieval practice)

Trying to recall is what makes memories stronger — much more than reading again. Close the book and write down what you remember, then check. A big review of learning research (Dunlosky et al., 2013) rated practice testing and spaced practice the two most useful study methods, and rereading and highlighting among the least. Flashcard Forge does this for you.

📅 Space it out

Review just before you would forget: after about 1 day, 3 days, 1 week, 2 weeks and 1 month. Each review takes less time than the last. The review planner ↓ puts those dates in your calendar.

🔀 Mix topics (interleaving)

Instead of 30 minutes of one kind of problem, mix two or three kinds. It feels harder, but you learn to tell them apart and remember better.

💬 Explain it simply

Ask yourself “why?” and “how does this connect to what I know?”, or explain it out loud as if to a 10-year-old. Gaps in your explanation show you what to review.

🖼️ Words + pictures

Put the same idea in words and in a drawing, diagram or timeline. Two routes to one memory make it easier to find again. Quietly saying things aloud helps too.

😴 Sleep, move, focus

Sleep is when the brain stores the day's learning — practise, sleep, then test yourself the next day. Regular exercise helps memory, and one thing at a time beats multitasking: phones away while you learn.

How to master them: a 4-week plan

About 15–20 minutes a day. Always test first, then look, and write your score down (your results are saved below).

Week 1 — Stories and chunks
  • 📝 Word list, 10 words, untimed: link them in a story.
  • 🔢 Number cards: read them in chunks of 2–3.
  • Next morning: write yesterday's list without looking.
Week 2 — Build memory palaces
  • Write two routes of 10 spots in the palace trainer.
  • Place 10, then 15, then 20 words.
  • Use a palace for a real shopping list.
Week 3 — Numbers into pictures
  • Learn 10 Major-system words a day with the trainer.
  • 🔢 Two-digit number cards: see the word, not the number.
  • Remember a phone number or PIN hint this way.
Week 4 — Combine and speed up
  • Put Major words into your palaces: 20, then 40 digits.
  • 📝 Word list levels, now timed.
  • Real life: 5 new names, a short speech, 10 words in another language.

Strong50+80+ in 5 minA deck of cards in under 10 min

Memory competitors go much further (hundreds of digits in 5 minutes), but they train daily for months with exactly these methods.

Common mistakes
  • Images too plain or too similar — make each one strange and different.
  • Too many items on one spot of a palace.
  • Only rereading instead of testing yourself.
  • Never reviewing: without a review after a day, most of a new list is gone within a week.
  • Training only games: they train the skill you play; use the techniques on real things to feel the benefit.
