メジャー・システムは英語の音声に基づいている。学ぶ単語は、このサイトをどの言語で使っていても 常に英語 のままである。日本語でも、スウェーデン語でも、中国語でも、ロシア語でも、使うのは同じ英語の単語リストである。流暢である必要はなく、約 100 個の簡単で鮮やかな英単語を見分けられれば十分で、多くの人は1回の学習で覚えられる。
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.
Tap a digit to see its memory hook
Each digit covers a family of sounds. The word uses whichever letter from the family sounds most natural. Both are equally correct.
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.
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.
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.
