Black Holes & Winning

At the center of every galaxy sits a black hole, the top-tier objective and the way to win.

The black hole stays visible even when zoomed out, holds a garrison of megaprobes, and starts out neutral.

Attacking

Drag from one of your suns to a black hole to send super-probes. On arrival every 100 super-probes becomes 1 megaprobe and any leftover is lost, so an attack needs at least 100 super-probes. The megaprobes fight the black hole's garrison just like a sun fight. Finish with more than the defender and the black hole is yours. You can attack a black hole in any galaxy, including from another one.

Collapsing (the win)

Once you own a black hole and have built its garrison up to 10,000 megaprobes, click it and choose Collapse to win the galaxy. Reinforce a black hole you own by sending it more super-probes; every enemy attack wears its garrison down.

Collapsing wipes the entire galaxy, including its planets, suns and everyone based there, and those players respawn in another galaxy. Galaxies do not reset on a timer: new ones spawn as the existing ones fill up, and a collapsed one frees its space. Winning pays out 10,000 energy as a prize. A solo winner takes it all; in a clan win every member gets the full 10,000. Energy stays with you across the respawn, so a win gives you a head start on tech upgrades.
