Jewel Quest Mysteries: The Seventh Gate is the third installment of a popular Jewel Quest spin-off series, where Emma Pack embarks on a perilous quest to find her missing loved ones. With the help of an old flame and daughter, Marco and Natalie, respectively, they must navigate through Ancient Greece before a volcanic eruption destroys an ancient lost city.
The gameplay follows a similar pattern to its predecessors, with players visiting locations across a map screen, completing objectives, and solving puzzles to progress. The twist is that each location has its own set of challenges, including finding hidden items, fixing objects using specific items from the inventory, and playing traditional Jewel Quest-style jewel boards.
Throughout the game, players will encounter various logic puzzles that require Emma's journal for guidance. Additionally, collecting jewels in each location allows for the purchase of power-ups to aid in jewel board gameplay. Between chapters, a scrolling screen provides an opportunity to find hidden items, earning more jewels and progressing through the story.
