There is no limit on how many lines the player can clear, and the player only loses when the blocks reach the top of the field. The blocks are invisible for increasing longer time periods as the level progresses. Blocks alternate between being visible and invisible. The bonus level is a semi-invisible level. Once all twenty levels are beaten, the player enters the bonus level. There are a total of twenty levels, each one at a higher speed than the last. Every line cleared is worth only one, unlike in Marathon Mode. Players have to clear ten lines per level while scoring as many points as possible. Survival Mode is similar to Marathon Mode. If the player loses by reaching the top, the score does not count and is not recorded in the high score list. Special moves called t-spins are also worth extra points. Clearing multiple lines with a single piece scores more points. Ultra Mode challenges players to score as many points as possible in two minutes. The speed is automatically set to the lowest setting. The time required to clear all the lines is recorded as the score. Sprint Mode requires players to clear forty lines as quickly as possible. The game ends once level fifteen is completed, and the score is recorded and added to the high score list if the user has a registered account. Once the goal has been reached, the level and speed increases and a new, higher goal is set. For instance, clearing a single line is worth only one, while clearing four lines with a single piece is worth eight lines. Clearing multiple lines with one piece is worth more than the actual number cleared. In Marathon Mode, players have to clear a specified number of lines while trying to score as many points as possible. As such, Tetris Friends permanently shut down on that date.
