REA Reaction

Unfinished Case of Holmes was a paper-based play-at-home puzzle game with a companion app that facilitated story, hint, and player progression.

While the app wasn’t fully translated into English and the hint system left something to be desired, this affordable game offered a variety of puzzles and some fun twists on more common puzzle types.

Unfinished Case of Holmes wasn’t a must-play, but if you’re into puzzle games, it would absolutely be worth a play through . Give this one a shot on a rainy day.

The Unfinished Case of HOLMES's components fanned out.

Who is this for?

  • Puzzle lovers
  • Any experience level

Why play?

  • It’s affordable
  • Some interesting puzzles


Sherlock Holmes had left this case unsolved. We stepped in to investigate a mysterious death.

In-game: A colorful Aboriginal mask over a text about the myth of the Rainbow Serpent.


Unfinished Case of Holmes included a collection of paper-based puzzles and an app interface.

In-game: An assortment of unusual items paper.


Unfinished Case of Holmes solved linearly, guided by an app.

For each puzzle, the app delivered narrative context and informed us which puzzle components to rely on. We could also take hints through the app. The puzzles came together through the printed components we’d received in the mail.

In-game: A folder with a piece of paper with a matrix of clock faces, and an envelope labeled, "Level 3."


+ iDventure printed on quality paper stock.

+ Each individual component was deliberately designed.

+ There was a good variety of interesting and challenging puzzles. Although primarily paper based, iDventure created interactive pieces. Unfinished Case of Holmes didn’t feel like homework worksheets.

+ The puzzles offered more depth than we’ve come to expect from paper-based play-at-home games. We appreciated the layered challenges that we could sink our teeth into, but still solve, as a series, in one play through.

– Although the puzzles were complex, if we got far enough, the solutions were brute-forceable. We could narrow down possible solutions and guess a few times until we found the right answer. (The app punished hints, but not incorrect guesses.)

– The punitive hint system wasn’t adaptive enough. At one point, we needed to take three hints before we received any helpful information. (The first two only gave us information we’d already deduced.) The app deducted time for each of these three hints, which felt unnecessarily punitive, especially since we’d figured so much out on our own.

– Some of the app’s interface had not been translated into English (which isn’t an issue if you read German).

Unfinished Case of Holmes was an affordable, worthy opponent.

Tips for Playing

  • For the Amazon version, iDventure sells two modes for Unfinished Case of Holmes: Expert and Standard. According to their website, “expert mode is with less tips and suitable for people with more experience with Escape Room games.”
  • iDventure also offers a downloadable version that requires more set up time.
  • We played the Amazon version in Expert mode.
  • For any version, you will need to download the app (available for IOS and Android) and have an internet connection.

Purchase iDventure’s Unfinished Case of Holmes, and tell them that the Room Escape Artist sent you.
