Cryptarithm is a classic numerical puzzle. In the addition example, all the digits are replaced with letters: WORD + WORD = WORD. Identical letters equal the same digit, different letters equal different letters, and the first letter of the number is not zero. Put the digits back in their place!
All puzzles are made up of real Russian words: LAD + BAL = FRAME, SEA + THUNDER = GRASS... Each has exactly one solution, and it is found logically: look for hyphens, outermost columns, and repeating letters.
