Cos'è il Major System?

Importante - per tutte le lingue

Il Major System si basa sulla fonetica inglese. Le parole che impari sono sempre in inglese, indipendentemente dalla lingua che usi su questo sito. Se stai studiando in svedese, cinese, russo o qualsiasi altra lingua, utilizzi comunque l'elenco di parole inglese. Non hai bisogno di essere fluente - devi solo riconoscere circa 100 parole inglesi semplici e vivide. La maggior parte delle persone le impara in una sola sessione.

The idea in one sentence

Map each digit to a consonant sound.
Build a word. Make it vivid. Never forget.

3 = M · 1 = T · 4 = R → MoToR → picture a spinning motor

The Major System converts numbers into words by mapping each digit 0–9 to one or more consonant sounds. Vowels cost nothing · use them freely to complete real words. Each word becomes a vivid image. Images chain into scenes. Scenes are impossible to forget.

The 10 rules · tap any digit

Tap a digit to see its memory hook

Silent fillers: Vowels (a e i o u), H, W, and Y carry no digit at all. Use them freely to build natural words from any consonant sequence. WHiTe = 1. HoNeY = 2. WoMaN = 32.

Same digit, different letters

Each digit covers a family of sounds. The word uses whichever letter from the family sounds most natural. Both are equally correct.

Bomb

B is silent at end only B·M counts

93

B + M

Comb

B is silent at end only K·M counts

73

K + M

Tomb

B is silent at end only T·M counts

13

T + M

Road

D is the sound, not T same digit 1

41

R + D

Duck

D not T both are digit 1

17

D + K

The system is over 300 years old and refined by memory champions ever since. Modern competitive memorisers use it to encode thousands of digits of pi, entire decks of cards, and long sequences of random numbers. The principle never changes: a vivid, concrete image is far easier to recall than an abstract digit.

Pi to 10 digits · five pairs, five images

3 · 1 · 4 · 1 · 5 · 9 · 2 · 6 · 5 · 3

Mitt

M + T

Your scene

A mitt slides down a road, lands on a giant lip, leaves a notch in it, then gets squeezed like a lime.

Five images, one absurd scene, one ten-digit block of pi permanently encoded. That is the system.

How to use this on PlayMemorize

1

Learn the rules first

Spend 10 minutes with the 10-rule table above until the digit–sound mapping feels natural. You do not need to memorise it perfectly · it clicks with use.

2

Study mode

See each number alongside its word and emoji. Go through the 00s, then the 10s, one group at a time. Say the word out loud while looking at the number.

3

Learn mode

See the number only. Recall the word from memory. Flip to check. Repeat any you missed. Once you can go through a group without errors, move to the next.

4

Play pi

Now play the pi game. As you tap through each six-digit group, the three-image story fires with your fingers. Shape and story reinforce each other from every tap.

The Major System is a mnemonic technique dating to the 17th century. The 100-word list, diagrams, and this guide are by Christoffer De Geer. The Major Pincode System (pairing this word list with numpad muscle memory) was devised by Christoffer in 2024.
