Mnemonic hints

Most digits are obtained by counting the number of letters in the word.

Sometimes lateral thinking is required, such as 'nun', which sounds like 'none', as a suggestion for '0'.

Suggestions are random. If none are suitable, just try again.

The best memory aid is the one you remember.

Combine multiple suggestions into a single memorable one.
