Hello, I've recently released my first puzzle game and I'm curious what you think about it. Your goal is to figure out the correct arrangement of oxygen atoms. Rules: 1) Oxygen atoms cannot be adjacent to each other, even diagonally 2) Numbers next to rows and columns tell how many oxygens should be in them 3) Each carbon atom needs 2 adjacent oxygens Stuck? Press the hint button, which will explain how to come up with the next move.
