Tetris is the best-selling mobile game of all time, with more than 100 million paid downloads on cell phones around the world.
That's according to the companies behind the 25-year-old game, which plan to formally announce the milestone on Thursday.
Created by a Soviet programmer in 1984, Tetris rode to popularity on the Game Boy in 1989. Millions of people have continued to play it since, on gaming consoles and over the Web, as well as on mobile devices.
The game's neat interface, simple controls and addictive nature make it especially well-suited for mobile gadgets. These include the iPhone as well as simple cell phones.
