The O Watch is an open source Arduino based smart watch kit designed for kids to create their own watch and learn the basics of coding, 3D design, and band making. http://theowatch.com/
Use the four O Watch buttons to slide the tiles horizontally or vertically. Combine similar tiles to reach 2048 and beyond.
This sliding tile game was inspired by the 2048 game by Gabriele Cirulli https://github.com/gabrielecirulli/2048
