The sun is gone. The world still needs power. Meet Atlas: a little fusion reactor with a very big job.

Spintal is a physics-based incremental game about turning atom collisions into energy. Start small, experiment with your setup and help Atlas produce more and more electricity.

Small atoms. Big impacts.

Click behind an atom to blast it into another, or hold and sweep your cursor to keep them moving. Every collision generates energy. Hit harder to get more out of it.

Make your reactor work for you

Place bumpers to keep atoms bouncing, then use barriers and one-way gates to shape their routes. Add quantum collectors to pick up loose quanta. Your setup keeps working without constant clicking while the game is running.

A skill tree that grows with you

Hard collisions can release quanta. Sweep them up and spend them on new skills. Explore 84 skills across eight branches as more of the tree is revealed. Quanta unlock new possibilities; energy upgrades the ones you already own.

From uranium ore to antimatter

Spend your energy on more atoms, more speed and more powerful collisions. Work through seven fuel grades, from Uranium Ore to Antimatter, and turn a modest reactor into a much bigger energy producer.

Give it a surge

Bring atoms together with Implosion, speed them up with Heat Surge and boost their energy output with Power Surge. Shockwave and Mass Charge complete your five active abilities. As you progress, unlock the Fuel Injector, Fission and Accretion Core for new moments to jump in and act.
