The method that turns pi into muscle memory and vivid imagery at the same time. Two anchors for every two digits.
Most techniques for memorising numbers rely on one memory channel. The Major Pincode System fires two channels simultaneously, both anchored to the same act of tapping a digit.
Pi is split into groups of six digits. Each group is the unit you memorise: one numpad shape your fingers trace, and one three-image story your mind holds. To build the story, the group splits into three pairs, each pair giving you one word via the Major System. Three words become one scene. You memorise the scene. The numpad shape and the scene reinforce each other every time you tap.
The MemorisePi numpad is a standard phone keypad. Every phone, ATM and payment terminal in the world uses this exact layout. You already know where every digit lives.
1 2 3 across the top. 7 8 9 across the bottom. Same as every phone you have ever used.
When you tap six digits in sequence, your finger draws a connected path across the keys. The group 3-1-4-1-5-9 makes a shape you can feel: top-right, top-left, middle-left, top-left, centre, bottom-right. Three short strokes woven together. After enough repetitions the whole path fires as one gesture, before you consciously think about any individual digit.
The Major System is a 300-year-old technique used by every serious memory competitor. It maps each digit 0 through 9 to one or more consonant sounds. You build a real English word from those consonants, adding vowels wherever you need them. That word becomes your image.
The words are always English — in every language. The Major System is built on English phonetics. Whether you use this site in Swedish, Chinese, Russian, or any other language, the digit-to-consonant mappings and the word list are English. That is not a limitation — it is how the system works. You do not need to be fluent in English. You only need to recognise roughly 100 simple, vivid English words like mitt, road, lip. Most people pick these up within a single session.
Every pair of digits within the group gives you two consonant sounds. Two sounds give you one word. One word gives you one image. Three pairs give you three images. Chain them into a single bizarre scene and you have the whole group.
Take the pair 31. Digit 3 maps to the sound M. Digit 1 maps to the sound T. You need a word with M then T. Add vowels freely: m-i-TT = Mitt. That is your image. A big winter glove.
Take the pair 59. Digit 5 is L. Digit 9 is P. You need L then P. Add a vowel: L-i-P = Lip. A giant lip. Done.
The 10 rules below are the complete system. Once you know them you can find a word for any pair within a group, and chain those words into a scene you will not forget.
| Digit | Sounds | Why it sticks |
|---|---|---|
| 0 | S, Z | Zero starts with Z. S makes the same hissing sound. |
| 1 | T, D | T has one downstroke. D is the voiced version of T. |
| 2 | N | N has two downstrokes. |
| 3 | M | M has three downstrokes. |
| 4 | R | fouR ends in R. |
| 5 | L | L equals 50 in Roman numerals. |
| 6 | J, SH, CH | J looks like a 6 rotated. Shoe, jaw, chain all share this sound. |
| 7 | K, G, C | K looks like two 7s back to back. |
| 8 | F, V | Handwritten f has two loops like the digit 8. |
| 9 | P, B | A lowercase p looks like a 9. A lowercase b is a 9 flipped upside down. |
Vowels (a, e, i, o, u), H, W and Y carry no digit at all. Use them freely to build natural words. WoMaN = 32. Tomb = 13 (the B is silent in speech). Mug = 37. The word only needs to contain the right consonant sounds, in order.
Pi is split into groups of six digits. Each group is one numpad shape and one story. The group splits internally into three pairs, each pair producing one word from the Major System. Three words become one scene. You memorise the scene. The numpad shape and the scene reinforce each other every time you tap.
Three pairs, three images. Your story: a mitt slides down a road and lands on a giant lip.
Pi = 3.14159265... The first group is 3, 1, 4, 1, 5, 9. This six-digit block is what you memorise as one unit. To build the story, split it into three pairs: 31, 41, 59. Look up each pair, get three words, chain them into a scene.
Three sub-movements that together make one six-digit shape. After a few repetitions the whole path fires as a single gesture.
A giant mitt 🧤 slides down a long empty road 🛣️, picking up speed. It launches off the tarmac and lands squarely on a giant pair of lips 💋. The lips pucker and spit it straight back up.
Bizarre and vivid. That is exactly right. The stranger the scene, the more reliably it comes back. When you reach digits 1 through 6 of pi in play mode, this scene fires automatically and the pairs come with it.
Open Play mode. Tap the full six-digit shape: 3, 1, 4, 1, 5, 9. While your fingers trace the path, hold the mitt-road-lip scene in your mind. Do it ten times in a row. By the tenth repetition the shape and the scene are one thing: the fingers fire the image, and the image confirms the fingers.
The three modes on MemorisePi correspond exactly to the three stages of learning a new six-digit group.
Most people can reliably recall pi's first 20 digits (the first three groups of six) after about 30 minutes spread across a few short sessions. The first group, 3.14159, typically takes 5 to 10 minutes. Each new group takes slightly less time as the method becomes familiar.
Once you have the first group solid, here is what comes next. Each group is one six-digit numpad shape and one three-image scene.
Mitt + Road + Lip (31, 41, 59)
Nacho + 
Lime + 
Leaf (26, 53, 58)
Book + 
Bomb + 
Gnome (97, 93, 23)
Fur + 
Chain + 
Shore (84, 62, 64)Four groups covers the first 24 decimal digits of pi. That is 3.141592653589793238462643...
Once you know all 10 rules you can find a word for any pair within a group, verify any word against its digits, and substitute your own images wherever you want something more personal.
| Digit | Sounds | Memory hook | Example words |
|---|---|---|---|
| 0 | S, Z | Zero starts with Z. S makes the same hissing sound. | Zoo, Sea, Sauce |

| 2 | N | N has two downstrokes. | Noah, Knee, Net |
| 3 | M | M has three downstrokes. | May, Emu, Mitt |
| 4 | R | fouR ends in R. | Ray, Road, Rain |
| 5 | L | L equals 50 in Roman numerals. | Law, Lily, Lip |
| 6 | J, SH, CH | J looks like a 6 rotated. | Shoe, Judge, Shore |
| 7 | K, G, C | K looks like two 7s back to back. | Cow, Cake, Cave |
| 8 | F, V | Handwritten f has two loops like the digit 8. | Foe, Fog, Fish |
| 9 | P, B | A lowercase p looks like a 9. A lowercase b is a 9 upside down. | Pie, Bus, Bone, Lip |
The Major System works on spoken sound, not spelling. Vowels (a, e, i, o, u), H, W and Y are always silent and carry no digit. Some consonant letters are also silent in certain English words: the B in Tomb (= 13), in Comb (= 73), in Bomb (= 93). What matters is the sound you say when you speak the word, not how it is spelled.
The Major System is a mnemonic technique dating to the 17th century. Christoffer did not invent it. The Major Pincode System (combining the Major System with numpad muscle memory) was devised by Christoffer De Geer in 2024. To his knowledge, nobody had formalised this combination before.
