Gamer alert -- you can now play Tetris on your Roku

Most people don't think of a set-top box as a gaming device, but that concept has been changing recently. Amazon's Fire TV and  Google's new Nexus Player are both enabled with capability that has the gamer in mind. Now Roku is stepping up as well.

The company announces that the classic game of Tetris is now available to its customers. "Casual gaming is a great feature available on Roku players and is perfect for a little friendly competition on family game nights. The addition of the Tetris game to the Roku Channel Store provides another great option for a fun, engaging game to keep your whole family entertained".

This year marks the 30th anniversary of the popular and challenging puzzle game. If you haven't played it before, then you'll find yourself placing dropping blocks of various shapes together as best as possible, and at an ever-increasing rate of speed.

Roku also claims "As an added bonus, you can turn back the clock and experience the Tetris game with a special nostalgic theme that is sure to bring back fond memories for seasoned Tetris fans".

The game comes in two versions -- free and Premium, with latter costing $4.99. You'll also need the latest hardware, meaning either a Roku 3 box or the Streaming Stick. Fire up either device and head to the channel store to grab your copy.
