Event Horizon: Black Hole Idle - a black hole grows from matter

In Event Horizon: Black Hole Idle, you lead a black hole and consume rocks, satellites and planets to grow on cosmic scales. This is one of the games about growth through the absorption of matter. Here you can see the lensing of light and the rupture of large bodies.

How to collect the first mass

  1. Bring the black hole to the nearest rocks and debris.
  2. Catch satellites and planets as they appear on the timer.
  3. Wait for tidal forces to tear large bodies apart.
  4. Collect debris and convert it into mass and energy.

What does a tree give in Evolution?

Energy goes into the Evolution tree for the radius of attraction, income and speed. It has Gravity, an Accretion disk, Satellites and Relativistic jets. Each upgrade helps you pull larger bodies and lift mass faster.

When to use big bang?

Big Bang is needed to reset the current cycle for permanent bonuses. Energy accumulates even between sessions, just like in Black Hole: Eat the Universe. After the reset, you reinvest the stock into Evolution and enhance the next growth.
