Balthazar Stone Escape Room Type Game by Mystery Agency

Can you unlock the ancient chest, find the Balthazar Stone and break the ancient curse?
Join Elsa Winslow on her journey to Sharktooth Island. To solve the mystery, you must unlock an ancient treasure chest, find Balthazar’s Stone and break its ancient curse.
Similar to an escape room game, this mystery presents you with a wooden chest locked a metal combination lock, and leaves you to work out how to open it and find and solve the mystery.

My family enjoyed this. It is not too easy and not too hard. It has been opened and played, however, we were very careful not to write and ruin the game. It was re-assembled as instructed for brand new play and someone else's enjoyment.
