A series of sabotages has shocked Lucky Llama Land! Multiple attractions at the theme park were tampered with. Players start their investigations and combine clues about the days of the crimes, perpetrators, tools, and crime scenes. They need to generate the right number code and use the key to put the saboteurs behind bars. In the end, it's not necessarily the fastest investigator who wins the game, but the most efficient one.

The 3rd game in The Key series by Thomas Sing, this one introduces new clue types and puzzles for players to solve. A replayable mystery game.
