OSAKA--The classic Tetris tile-matching puzzle game just got bigger, at least in Osaka.

Through projection mapping technology, visitors can play the game on a 12-meter-tall wall at the observatory of Abeno Harukas, the nation’s tallest building, in Osaka’s Abeno Ward.

The event at the 300-meter-tall skyscraper runs until Feb. 28.

Tetris marked its 33rd anniversary last year. The giant game event also coincides with the third anniversary of Abeno Harukas.

“I got so carried away by the game that I wasn’t even looking at the night view,” said Mayuko Wakayama, 40, who came to the venue from Shiogama, Miyagi Prefecture, with her child.

Two people can play the game using one of three control stations.

Adults can play a maximum of three minutes when they pay the entrance fee of 1,500 yen ($13.30) to the observatory.
