Open your casebookHow to solve these detective logic puzzles
- Open The Missing Museum Key to begin. Complete it to unlock The Library After Hours, then The Midnight Observatory.
- Inspect each evidence card and compare it with the character statements. Distinguish reliable records from somebody’s claim.
- Use your notebook to organize times, locations and contradictions. Select an answer for every deduction before submitting your final conclusion.
- Ask for a hint if you need a nudge. An incorrect conclusion lets you investigate again; a correct one reveals a full explanation.
Reason at your own pace
These free mystery investigation games have no countdown. Estimated playtimes are guides, not limits. Start with 100 points: each hint costs 10, and each incorrect submission costs 5, down to a completed minimum of 20. Reading clues and changing unsubmitted answers are free.
A small casebook, made to finish
Three fictional, non-graphic cases build from a simple timeline to connected evidence and clock conversions. The characters and stories are original. All facts needed to solve a case appear inside it; no specialist knowledge or web search is required. Replay to improve your score, while remembering that the mystery’s answer stays the same.
