Play to set a charge, then submit it to the board.

How to play

  • Tap the reactor core to add charge by hand.
  • Spend charge on modules — each one produces energy automatically, every second.
  • Your reactor keeps earning while the tab is closed; come back for a welcome-back payout.
  • When your lifetime energy is high enough, Reboot to reset for a permanent production boost.

Strategy & tips

  • Early on, tap to afford your first Capacitor, then let auto-production snowball.
  • Always buy the cheapest module you can — steady growth beats saving for one big tier.
  • Check back after a break: offline earnings often buy the next tier outright.
  • Reboot resets your modules but multiplies all future output, so time it when growth stalls.
  • Each reboot compounds, so the earlier you can afford the next one, the faster you climb.

FAQ

Do I have to keep tapping?

No. Tapping only bootstraps your first modules. After that the reactor produces energy automatically, even while the tab is closed.

Does it really earn while I am away?

Yes. Offline progress is capped at eight hours, and you get a welcome-back summary of what your reactor made while you were gone.

What does Reboot (prestige) do?

It resets your charge and modules but grants a permanent production multiplier that stacks with every reboot — the long game.

Is my progress saved?

Yes, in your browser. Your reactor, modules and reboots are stored locally, and your best lifetime energy can go on the weekly leaderboard.
