PHILADELPHIA, Penn. – There are many ways to play the classic video game Tetris – on a PC, Smartphone or video game console.
But now, it can also be played on the side of buildings. It’s what organizers call the world’s largest game of Tetris.
This version of the game was created using computer-controlled L.E.D. lights on Philadelphia’s 29-story Cira Centre.
A few lucky players were given an arcade-style joystick to control the falling blocks.
The event was part of a celebration marking the video game’s 30th anniversary. It’s one of the best-selling video games of all time.
