The Mystery of Jewels: Adventure Match 3 is a match-3 puzzle game. In a summertime setting, the player collects gemstones from boards in sets of three or more adjacent identical ones. Their goals are to reach all targets per game and earn stars, points and coins.
Each level displays a central board covered with columns and rows of mixed-color gemstones. To the left of it, the player can review their star-collection progress, current score, number of available moves, and their targets.
The right side displays several boosters that include mallets that remove one gem from the board at a time, rockets that clear columns and rows, bombs that remove an entire board of gems and other items, and stars that shuffle all pieces on the board. The player receives free access temporarily and then buys more with their coin winnings.
The player swaps one piece with another to create a matching set. They also meet their targets by making special items when they align more than three at a time. For example, a set of five creates a sparkling rainbow gem that removes all of the same kind. The player can merge instead of swap special items to perform power moves as well.
The Mystery of Jewels: Adventure Match 3 rewards the player at the end of each level. The player can double their rewards with ad views. The game also supplies them with other opportunities for winnings. They can play a lucky spin wheel to earn coins and boosters.
