Cryptarithm
Game where digits are replaced by letters or other symbols in an arithmetic operation.
In a cryptarithm, a single symbol (letter or other symbol) replaces a single digit.
If the different elements form a meaning, then the cryptarithm is called an alphametic.
Example
Replace the letters with digits so that the numbers found produce an accurate addition:|
