Alphametic puzzles involve equations where digits have been replaced with letters, where the goal is usually to reconstruct the original equation, matching letters to numbers.

Alphametic puzzles involve mathematical equations where the digits have been replaced with letters or symbols.

The puzzle is then to reverse this process, and to determine which letters represent which digits by using the information given via the puzzle to narrow down the options. The solution should ideally be unique.

For example $A+B=AC$ has the unique solution $A=1, B=9$ and $C=0$.
