The App Store version offers 3 mysteries per day and helps support the game!
Objective: Identify the killer among the animals on the farm.
1. Collect Clues: Click on the speech bubbles above animals. They will tell you about their relatives or things they saw.
2. Build the Tree: Click an animal, then click another to link them as Parent/Child. The older animal is automatically set as the parent. (HINT: Parents are always 20-39 years older than their kids.) Use the clues to reconstruct the genealogy.
3. DNA Testing: You have 3 DNA tests. Testing an animal reveals their exact relationship to the killer (e.g., "The Killer's Cousin"). Testing the killer is an automatic win!
4. Accuse: Once you are certain, select the killer and click ACCUSE. You must have used all DNA tests to make an accusation.
A new mystery is generated every day at midnight.
Welcome to mystery.farm, a daily genealogical murder mystery.
Every day at midnight, a new crime is committed on the farm. As the lead detective, your job is to reconstruct the family tree of the residents using DNA evidence and witness testimonies to identify the killer.
This game was inspired by the real-life investigation of the Golden State Killer. Investigators found two 3rd cousins of the killer, and then traced their geneaology to a shared ancestor. Then they worked their way down the family tree from that ancestor to find the one person who could have committed the murders.
The first draft of the game was a realistic murder mystery, but we later simplified it into this puzzle format using cute pixel art animals. "Why not?" we thought, and made it a cute animal murder mystery.
I am a solo developer who loves puzzle games. My first game was Connecdoku, a word game with elements of NYT Connections and Sudoku.
