Your final score is determined by the number of points you’ve earned by the end of the game.
You score points for each Tetrimino dropped and each line cleared. Clearing multiple lines at once scores more points. Clearing a line immediately after clearing a previous line scores a Combo bonus. Performing a T-Spin also scores points.
You can also score Back-to-Back points by setting up multiple high-scoring actions in a row, like Tetris™ Line Clears and T-Spin Line Clears.
