Tetris.PhillyThe world’s largest Tetris game will be played on the Cira Centre office building in Philadelphia this Saturday, from 7 to 10 p.m. Video game enthusiasts and techies of all ages will gather at Eakins Oval, located in front of the Philadelphia Museum of Art, to play the Tetris game on the 29-story tower.

Dr. Frank Lee, the founder of Drexel University’s Entrepreneurial Game Studio, will turn Cira’s LED arrays into a fully interactive version of the Tetris game, in honor of both Tetris’ 30th anniversary, as well as to kick off festivities for Philly Tech Week. Visitors will be able to play the game using an arcade-style controller at Eakins Oval. More than 100 people, randomly selected from an online lottery, will also have the opportunity to play.

Guest players will include: Michael Nutter, mayor of the city of Philadelphia; Henk Rogers, managing director of The Tetris Company; Jeff DeVuono, EVP and senior managing director of PA region, Brandywine Realty Trust, which owns Cira Centre; and Chris Wink and Brian Kirk, co-founders of Philly Tech Week.
