Event Horizon: Black Hole Idle

You are a black hole. Drift through space, swallow rocks, moons and planets, and grow up a ladder of cosmic scales. Energy keeps flowing even while you're away. Spend it on an evolution tree of upgrades: gravity, accretion disk, satellites, relativistic jets. Then trigger a Big Bang to restart stronger with permanent laws of physics. Real ray-traced gravitational lensing, tidal disruption of planets and a catalog of real celestial bodies to collect.

Move the black hole by swiping or dragging on the screen (arrow keys or WASD on desktop). Pull in matter to earn mass and energy. Large bodies like moons and planets arrive on a timer: get close and tidal forces tear them apart, then catch the debris. Spend energy in Evolution to grow your pull radius, income and speed, fire jets with the round button, and climb to the next scale. When it pays off, use the Big Bang button to reset for permanent bonuses. Pinch or scroll to zoom.
