Can you crack the secret code? Every puzzle hides a secret code of different digits.

Cross out what cannot be true, follow the trail of hints, and deduce the one and only answer. • 240+ pure-logic deduction puzzles, no guessing required • Three levels that grow from 3-digit to 5-digit codes • Every puzzle has exactly one answer, provable by elimination • Picture hints work in black and white — no color needed • Full solutions at the back Part of the Crack the Code for Kids series — real reasoning, screen-free.
