Whoever completes the longest path wins! But beware of collisions!
When Zach is not knee-deep in circuits and code, you can probably find him around a table covered in board games. For a long time now, a little project has been brewing in the back of his mind, designing a board game from the ground up, but not just any board game. Zach wants to create a tile-based game where the tiles electronically interact with each other the moment they snap together. It was featured on the Digkey YouTube channel in this video.
