The reactor is under your control. By tapping the core, you can generate energy and purchase various generators — from a simple dynamo and solar panel to a fusion torus and a Dyson sphere. There are ten installations, each producing energy even when the game is closed.
Each installation you build is visible on the screen. They take their place on the ring around the reactor and grow as you upgrade them. The core itself goes through ten stages, from «Spark» to «Nova», changing colour, lattice and armature along the way.
Quick taps charge the Overdrive mode, where each tap gives ten times more energy for ten seconds. Use this function wisely to boost the reactor at the most crucial moments.
If you've accumulated enough energy, restart the reactor. Your progress will reset, but you'll gain cores, each permanently increasing your income by 10%. The further you go, the faster the next run will be.
Returning to the game pays off: the reactor continues to work offline for up to eight hours, and bonus containers arrive periodically. Progress is saved, and no login is required to play.
How to play
Tap the central core on the screen to accumulate energy — each tap contributes to the total. Use this energy to power the generators below, which then work independently without the need for further tapping.
Rapid tapping fills the heat meter, and once full, it activates Overdrive mode. For ten seconds, every tap will generate ten times more energy.
Save enough energy in a single run to unlock the reactor restart. This action resets your progress but awards you cores, each of which permanently increases your income by 10%. Restarting is beneficial as subsequent runs become significantly faster.
The reactor continues to operate even when you're not playing — up to eight hours of offline production await your return. All ad bonuses are optional; you can make progress without watching anything.
