A ditloid is a type of word puzzle, in which a phrase or quote must be deduced from the numbers and abbreviated letters in the clue. Examples include:

• 3 BM = 3 Blind Mice
• 7 DS = 7 Deadly Sins
• 20 V on a D = 20 Vertices on a Dodecahedron
• 24 H in a D = 24 Hours in a Day
• 52 C in a P = 52 Cards in a Pack
• 20000 LU the S = 20000 Leagues Under The Sea

Common words such as 'the', 'in', 'a', 'an', 'of', 'to' etc. are not normally abbreviated.

The name 'ditloid' was given by the Daily Express newspaper, originating from the clue: 1 DITLOID = 1 Day in the Life of Ivan Denisovich.
