Casual fun with Physical Chemistry! Most days you are a billions of protons — today you get to be one. As a single proton, you’ve got a lot to learn. But with luck and determination, you may just grow into a molecule.

This game is grounded in real science, developed in collaboration with scientists at the NSF-funded Center for Chemistry at the Space-Time Limit at UC Irvine. Use real forces to stick atoms together – and real tools to break them apart!


For those of you who are interested in a bigger challenge, check out these levels that were created as part of the Bond Builder Contest. (It's still going until October 29th, so feel free to create some levels that might be added to the official game... or just to share with your friends. Whatever!)

Love Story:

What a fun game. Love how you incorporated science. Usually these types of games are boring as hell. I was pleasantly surprised.

How can hydrogen attract protons when its electric charge is neutral?

Crazy, right? Read about how it happens:


Rated 3.5 / 5 stars

This is a good game, although it could be better by adding more types of particles/molecules/instruments. Great conept though.

Glad you liked it! And yes, we'll be adding more levels with extra physics - things like Oxygen atoms, and H2O molecules. Maybe even some current research that the scientists at CaSTL are doing. (They are doing some crazy stuff, let me tell you...)
