Walk around in a cell and solve puzzles... the puzzles are neat because as a biochemist, I can tell that they give the player a nice feeling for how proteins and especially big complexes work. If you are learning about the Electron Transport Chain in class, this game will make you an expert! It's great to play on its own as well. Everyone can play it, no prior knowledge required: it is very well designed!

The game is short. I want more, and so will you! Play it in your browser.

And please give the scientist who made it your feedback after playing!
