This is less of a strict "puzzle" game, more of a game about mechanisms and experimentation. Tightly designed, elegantly presented, Opus Magnum is an excellent way to stretch your brain a bit and have fun in the process. One of its greatest strengths is that it sets a goal, gives you the tools, then gets out of the way. You can be creative, efficient, or somewhere in between, so long as you achieve the desired output with your machine. It's by far my favorite "thinking" game at the moment, precisely because it's built to encourage making your own solutions instead of finding the developer's solution. Highly recommended.
