Major System Generator
Build your own word for every number from 00 to 99, then practise it until each one comes back instantly.

How to use the Major System generator
The Major System turns digits into consonant sounds, so every two-digit number from 00 to 99 can become a word you can picture: 32 is M + N, so “moon”; 91 is P + T, so “pot”. This tool gives you a slot for each number with its sounds shown alongside, so you can build your own list and then use it.
- Fill in a word for each number using the sounds shown next to it. Vowels, and the letters w, h and y, don't count, so they're free to fill the gaps.
- Choose words you can see clearly: concrete objects and people beat abstract ideas.
- Use the Convert tab to turn a long digit string into your words, two digits at a time.
- Drill your list in the Practice tab: it shows numbers in random order, you answer, then check yourself against your own word.
Frequently asked questions
- Is the Major System generator free?
- Yes. You can build, convert and drill a list without an account. Signing in lets you save named lists and come back to them.
- Do I need all 100 words before I start?
- No. Practice drills whichever numbers you've filled in, so you can start with 00–09 and grow the list over time.
- Why doesn't Practice mark my answers?
- Your list is personal: "mat" and "mud" are both right for 31 if that's the word you chose. The drill shows your own word next to your answer and leaves the judgement to you.
- How is this used in memory competitions?
- Athletes turn long numbers into a chain of words and place them along a memory palace. It's the base system for numbers events such as Speed Numbers and Hour Numbers.
New to the method? Read the Major System guide for the full chart and examples, then put your list to work in Speed Numbers. To see the difference it makes, take the number memory test before you learn the list and again once you use it.
