It is a game about building functional computer by combining logic gates. Game arranged in series of small puzzles to make it digestible for people without electric engineering degree like me. You slowly build new components, so you can use them later as higher level abstraction until you get to the point of having to program your own computer to solve further puzzles. If you curious how computers work, this game is a gem.
