Locktale

Locktale is a story-driven puzzle game in which you decode secret messages using ciphers, symbols, visual tricks and logic challenges. Each level introduces a different encoding technique, and the story gradually unfolds as you crack the messages.

Decode the messages

Across more than 50 levels, you encounter common ciphers ranging from basic techniques used in Antiquity to tools from modern cryptography, alongside symbol-based ciphers and techniques created for the game. The puzzles are designed to be solved using information found within the game, without consulting external cryptography databases. Some require you to revisit solved puzzles for keys or data, study the provided hints, change the interface theme to find clues, or apply methods you have already learned to more complex ciphers.

Hints for every level

Each level has three levels of hints, from minimal to detailed, to help you work through its cipher. The game is designed to welcome players with different levels of familiarity with ciphers.
