Jewel Legend is a match-3 puzzle game with a gemstone mining theme. It displays a vertical board floating in the air under wood timbers in a mining tunnel. The player must complete tasks using match-3 rules to earn the most points possible across 100 levels.
Each board features a mix of valuable jewels in rows and columns, including diamonds, emeralds, rubies and sapphires. Within each level, the player rearranges the jewels into lines of three or more identical pieces to remove them from the board. They might need to make matches to earn a specific score, collect a certain number of specific jewels or other objects, or beat a timer.
As with similar games, Jewel Legend features boosters. The player can earn or create these helpful tools. For example, they can earn a pickaxe that removes a single jewel at a time, double arrows that undo the last move, and a bucket that removes jewels randomly. They can also create colorful dynamite sticks by matching four or more of the same jewels. These boosters blow away jewels from a row or column. By matching five or more jewels, the player can create rainbow-swirl bombs that blow away matching pieces across the entire board.
The game offers several interesting match-3 twists. The player must sometimes break ice blocks, but they don't need to break the ice from the outside. Instead, they can swap pieces underneath each block. Additionally, if the player runs out of moves, the game gives them a shuffle action more commonly seen in tile-matching games. It tosses all the jewels into a wooden barrel, shakes the container, and places the jewels back on the board in a new order.
