Players interact with various matching games in Circle Crush, using swipes to connect adjacent orbs of the same color. This connects multiple orbs, clearing them from the board.
The objective is to clear as many orbs as possible within a set time limit. The amount of orbs cleared is tied to the player's score. Circle Crush can be played directly in a web browser, without the need for a download or registration. As the player progresses, new orb colors and pairing mechanics become available, increasing the game's difficulty.
