Overview
The reactor is yours. Tap the core to earn energy and buy generators — from a dynamo and a solar panel all the way to a fusion torus and a Dyson sphere. Ten installations, each producing on its own even while the game is closed.
Everything you build shows up on screen: each installation takes its place on the ring around the reactor and grows as you upgrade it. The core itself climbs ten stages, from Spark to Nova, changing colour, lattice and armature as it goes.
Tap fast to charge the Overdrive: for ten seconds every tap pays ten times as much. Time your bursts and push the reactor when it matters most.
Banked enough energy? Restart the reactor. Progress resets, but you gain cores — each one permanently adds 10% income. The further you push, the faster the next run spins up.
Coming back pays off: the reactor keeps working offline for up to eight hours, and every so often a container full of bonuses arrives. Progress is saved, and no login is needed to play.
