Iconic Russian puzzler Tetris, first developed in 1984, has now achieved 100m paid downloads across all mobile formats since EA Mobile bagged the mobile rights in 2005.
It was first made available for mobile by G-Mode in Japan in 2001, so the lifetime sales total is actually even greater than 100m.
Despite Tetris's veteran status it still sells 20m a year and 55,000 copies a day, and is the tenth biggest selling app on the Apple App Store this week.
It is currently available across 800 handsets, and via 300 distributors. 75 per cent of current sales are on feature phones, with the rest on smartphones including iPhone.
