Players need to match gems of the same color in the game, eliminating them can also trigger a chain reaction to obtain higher scores and rewards.

The level design of the game is very clever, each level has a variety of different star arrangements and goals, such as eliminating a certain number of stars of a specific color, obtaining a certain score, etc. Players need to develop elimination strategies according to different goals and star arrangements, sometimes they need to start from a farther area, and sometimes they need to continue to eliminate on the basis of existing stars.
