Tetris turns 30 this year, and fans are being asked to think big for the anniversary celebrations.

Over on Meetup, Tetris fans are being asked to assemble a big gathering of like-minded players to share in the love for the classic block puzzler. The ten meet-ups with the largest attendee count before May 28 will each receive a Tetris celebration pack to inject more awesome into their event.

The top events will each get Tetris 30th Anniversary shirts, a copy of Jenga Tetris signed by the game's creator Alexey Pajitnov, and more Tetris-themed merch.

A further three meet-ups in the US will receive bonus packs worth $500.

So, Tetris part round my place anyone?
