Turn numbers into words with the major system, race to encode phone numbers, dates and digits of pi, then decode words straight back into numbers.
Was this fun?
How to play
The major system maps each digit to consonant sounds, so any number can become a memorable word and any word can be read back as a number. Each timed challenge asks you to either encode a string of digits into a word, or decode a word into its number, across themes like phone numbers, dates and pi.
A legend shows which consonant sounds map to each digit
Encode: coin a word whose consonant sounds spell the digits
Decode: read a word's consonants back into its number
Daily is a shared round; Practice generates a new one
Controls
Desktop: type your word or number and press Enter or click Submit
Phone & tablet: tap the field to type your answer, then tap Submit
Tips & strategy
Lean on the legend until the digit-to-sound pairings become automatic
Vowels are free, only the consonant sounds carry the digits
Faster correct answers score more, so trust the mappings once they click
