About Tetris

Tetris was created by Soviet game designer Alexey Pajitnov in 1984. It became one of the best-selling video games of all time and has been released on virtually every platform. The name comes from the Greek prefix "tetra" (meaning four) and tennis, Pajitnov's favorite sport.

How is the score calculated?

1 line = 100 × level, 2 lines = 300 × level, 3 lines = 500 × level, 4 lines (Tetris!) = 800 × level.

How does the level increase?

Every 10 lines cleared advances you one level, making pieces fall faster.
