Cryptogram Collections
Collections bring together cryptogram puzzles around a theme — a person, a period of history, a subject, or an occasion. Rather than browsing by category or difficulty, collections give you a curated set of puzzles that share something in common, making it easier to spend time with a topic you care about.
Each collection includes puzzles across all difficulty levels. Some are tied to calendar occasions — Presidents Day in February, Earth Day in April, Independence Day in July — while others are available year-round. All are free, require no signup, and work on any device.

About These Collections
Every puzzle in every collection uses a unique letter substitution cipher — each letter of the alphabet is swapped for a different one, consistently throughout the puzzle. You decode it using pattern recognition, letter frequency, and logic. Our solving guide covers strategies for beginners and experienced solvers alike.
All collections are free to use and print. Teachers may use them for classroom instruction without permission — please credit WebCryptogram.com on printed copies. Browse puzzles by category, difficulty, or author, or solve the daily puzzle.
