TIME - The game starts with a 1:00 countdown timer that will end the game when it’s out of time. You can regain time from Gems that reward extra time however the timer will not exceed 1:00.

CASCADE LINE CLEAR - Maneuver the falling Tetrimino to fit them together within the Matrix to create a line and trigger a Cascade Line Clear, fill every square within a single row.

TETRIS LINE CLEAR - Completely filling four rows of horizontal lines at one time with an I-Tetrimino results in a Tetris Line Clear.
