Philadelphia gamers play skyscraper Tetris
Fans of the classic video game Tetris have helped mark its 30th anniversary by bringing the game to new heights.
Players in Philadelphia used a joystick to control the pieces displayed on the 29-storey Cira Centre building, 437 feet (133m) high.
Organiser and game designer Frank Lee already holds the Guinness World Record for the world's largest architectural video game display for a similar event with the game Pong in 2013.
