CES crowds can be tough — especially toward the end of the week. You’re physically and emotionally drained, and you’re pretty sure you’ve seen everything the consumer electronics world has to offer. And then something comes along to knock your socks off. Square Off was one such product, impressing the crowd at our meetup and walking away the winner of our hardware pitch-off.

The company’s first product looks like your run of the mill wooden chess board. And that’s part of the charm. Turn it on with the single button, and the system goes to work, tapping into chess AI software built by Stockfish and moving opposing pieces accordingly with an electromagnet attached to a robotic arm hidden under the board.
