Tetris is, without a doubt, the quintessential puzzler of our time. It's one of the few games that speaks to players of all ages and backgrounds, and it's widely considered one of the most popular games of all time. And since you can play it anywhere, from the XBox One to your iPhone, it's also the world's best distraction; we can only imagine how much productivity the world's lost from our collective obsession.
The Tetris MicroCard is an intriguing piece of tech that brings no-frills Tetris fun to a miniature device that's slim enough to go in your pocket or wallet. Based on the Arduboy, a credit card-shaped LED device that allows you to play 8-bit games, it's also got a microUSB port for quick charging on the go.
The transparent Tetris machine is only $49 and is available for preorder right now, although these devices aren't shipping until next spring. While they're perfect as holiday stocking-stuffers, you might want to throw in something else to tide your loved ones over until then.
