Types of cryptarithm include the alphametic, the digimetic, and the skeletal division.  

;Alphametic
: A type of cryptarithm in which a set of words is written down in the form of a long addition sum or some other mathematical problem. The object is to replace the letters of the alphabet with decimal digits to make a valid arithmetic sum.
;Digimetic
: A cryptarithm in which digits are used to represent other digits.

;Skeletal division
: A long division in which most or all of the digits are replaced by symbols (usually asterisks) to form a cryptarithm.
