This game is a faithful recreation of "Orthanc", one of the first graphic dungeon crawl role-playing games developed for the University of Illinois Urbana-Champaign's PLATO computer in the 1970s. The original was played on a PLATO terminal with a keyboard. (The PLATO version of "Orthanc" was inspired by "pedit5", which you can learn more about in Wikipedia.) The original PLATO terminals used plasma panels only capable of displaying orange and black. There is no sound. This implementation uses the touchscreen for all gameplay. You are an adventurer gaining experience and treasure by defeating monsters. Orthanc is easy to start but hard to put down.

Verdict

The call

The clearest difference is in-app purchases: Orthanc at none against Dark Blue Dungeon's 1. Orthanc also leads on ads (none vs shown). Dark Blue Dungeon's advantage is rating (4.4 vs 4.0) and ratings volume (50 vs 4). On price, review sentiment, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Dark Blue Dungeon holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Dark Blue Dungeon has 50 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 63% of Dark Blue Dungeon's written reviews are positive against 67% of Orthanc's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Dark Blue Dungeon ships an update every 3 weeks, Orthanc every 6 weeks. The most recent releases landed on September 23, 2026 and September 9, 2026 respectively.
