Bring chemistry to life through play!

Interact with the basic building blocks of chemistry in order to explore and solve challenges.

Acids & Bases: Remove protons from acids, then add them to bases while exploring the strengths of various acids.
Atoms: Use protons and electrons to build atoms and explore atomic size.
Covalent Bonding: Bond atoms to build molecules of various shapes and bond polarities.
Intermolecular Forces: Form IMFs of various types and strengths by building molecules of different polarities.
Ionic Bonding: Explore how ions of various charges interact to form ionic compounds.
Ions: Manipulate energy to add or remove electrons and form ions.
Phase Change: Add and remove energy to affect motion and intermolecular forces to create phase changes.
Equilibrium (New!): Disturb reactions to shift equilibrium and cause changes in the system.

Beat the challenges by using your knowledge to solve the levels, using the bank and targets as guides!

Unlock the sandbox to freely explore the rules of chemistry and earn achievements along the way.

Once you’ve mastered the challenges, take it to the next level by solving a level within a level in the later challenge levels to see how it all connects.

Ionic Bonding is free to play. Full access to Atoms, Ions, Covalent Bonding, Ionic Bonding, Acids & Bases, IMFs, Phase Change, and Equilibrium are available through monthly or yearly in-app subscription* or by using a valid login provided by your school.

Great Learning Experience!! Highly recommend

As a visual learner this game is hugely helpful to my understanding of concepts that I was struggling with. Fun and challenging at the same time. This game gives you a really hands on experience with Chemistry!

I would be a chemical engineer...

...If they had this when I was a kid. It’s brilliant! Got the subscription and I’m glad I did.

This games takes so much battery life away from and even overheats my computer. Some of the levels just freeze and I have to reload the page. I have had to reload a couple time losing my progress…. Plz fix your platform
