About Oliver Brennan

Oliver Brennan is the senior puzzle editor at Cryptogram Answers, where he has personally decoded and verified every level of the Cryptogram puzzle app by Gismart across all five supported languages: English, French, German, Spanish, and Russian. His work covers over 10,000 individual puzzle solutions, each one manually solved without automated tools and cross-referenced against the original source material for accuracy.

Oliver developed his expertise in substitution ciphers through years of puzzle solving, beginning with newspaper cryptograms in 2015 before transitioning to mobile puzzle apps in 2019. His particular strength lies in frequency analysis — the mathematical technique of identifying letters by how often they appear in a given language. This skill allows him to crack even the most challenging cipher puzzles within minutes, a process that might take a casual player hours of trial and error.

Beyond simply providing answers, Oliver takes care to verify the attribution of every quote in the game. Cryptogram levels feature quotes from historical figures, authors, philosophers, and public figures. Oliver checks each decoded quote against its original source to confirm that the game has attributed it correctly. Where discrepancies exist — a common occurrence in quote databases — he notes the correction so readers get accurate literary and historical context alongside their puzzle answer.

Oliver is fluent in English and French, with working knowledge of German, Spanish, and Russian — a skillset that makes him uniquely qualified to verify multilingual puzzle content. He updates the Cryptogram Answers database within 48 hours of any new level release, ensuring that players always have access to current solutions regardless of which language they play in.

His verification methodology follows a three-stage process: manual decoding, source cross-referencing, and multi-device testing. This rigorous approach ensures that every answer published on this site matches exactly what the game accepts, eliminating any ambiguity for players who are stuck on a particular level.

Oliver Brennan’s Approach to Puzzle Verification

Oliver believes that a puzzle answer site has a responsibility beyond simply providing solutions. The decoded quote must be accurate, the author attribution must be correct, and the answer must work in the actual game. His three-stage verification process was designed to meet all three requirements simultaneously.

The first stage — manual decoding — serves as an initial accuracy check. If the decoded text does not read as a coherent sentence in the target language, something is wrong and the level is re-examined. The second stage — source verification — catches attribution errors that exist in the game itself. The third stage — multi-device testing — ensures compatibility across different versions of the app.

This commitment to accuracy has made Cryptogram Answers the most reliable reference for Cryptogram puzzle solutions on the web. Oliver personally stands behind every answer in the database.
