My Memory Systems Toolkit

Three powerful systems I use to memorize numbers, cards, and abstract information.

The Major System

I use the Major System to memorize cards, numbers, dates, binary digits, etc. This is my primary number memorization system.

Why I Prefer the Major System:

  • More flexible than the Dominic System - can create words for any number combination
  • Works well for both short and long numbers
  • Easier to create vivid, memorable images

Example Conversion:

Number Sound Code Word Image
14 t/d + r tire A giant rolling tire
67 sh/ch/j + k/g shark A jumping shark

The Dominic System

I constructed my Dominic System after reading the legendary World Champion's book. However, I rarely use it since my first introduction was the Major System, which allows for more possibilities.

Sample Person-Action Pairs:

Number Pair Person (Initials) Action
07 James Bond (JB) Shooting
15 Albert Einstein (AE) Writing on blackboard
42 David Beckham (DB) Kicking soccer ball
When I Use the Dominic System:
  • For memorizing playing cards (each card maps to a person-action pair)
  • When I need to remember numbers as stories (combining multiple person-action pairs)
  • For memory competitions where speed with 2-digit numbers is crucial

Peg Systems

The basic peg system is useful sometimes. I use the number-shape and number-rhyme systems to remember certain items.

My Number-Shape System

Number Image Visualization
1 Pen A giant pen standing upright
2 Swan A white swan with curved neck
3 Heart A red Valentine's heart
4 Chair A wooden dining chair
5 Hook A pirate's hook hand
6 Smoking Pipe A tobacco pipe
7 Club A golf
8 hour glass An antique hour glass
9 Balloon An inflate balloon
10 Bat and Ball A tenis racket

My Number-Rhyme System

1 Gun A shiny revolver
2 Shoe A leather dress shoe
3 Tree A large oak tree
4 Door A red front door
5 Hive A buzzing beehive
6 Bricks A brick
7 Heaven An angel
9 Pine A pineapple
10 Hen A chicken
Example Usage:

To remember a 3-item list: Eggs, Milk, Bread

  1. Eggs → Gun shooting eggs
  2. Milk → Milk pouring from a shoe
  3. Bread → Bread growing on a tree

How I Choose Between Systems

When I Use... Best For Example
Major System Cards, long numbers, binary data Memorizing a 20-digit number
Peg Systems Short ordered lists (up to 10 items) Grocery lists, daily tasks
Dominic System Special cases needing person-action pairs Memory competitions, playing cards

Pro Tip: Combine Systems

For complex memorization tasks, I often combine systems. For example:

  • Use the Major System to convert numbers to words
  • Place those words in memory palaces
  • Use peg systems for the order of items
