How to play
A cryptarithm (or alphametic) puzzle is a puzzle where words are arranged in a mathematical expression with letters substituted for numbers. The most common mathematical expression is addition, but subtraction, multiplication and division problems can be turned into a cryptarithm by replacing numbers with appropriate letters. A few rules are usually established, such as: the leading letter cannot be zero, each letter must represent a unique digit, and solutions must be unique. Players can challenge themselves by trying to create their own cryptarithm, or they can try solving cryptarithms created by others.
