Introduction to Black Hole

Black Hole is one of the tabs in Galaxy Idle Clicker, and is the Tier 2 Prestige Layer.

Here you can Travel through a Black Hole after reaching the required amount of Light Years, as well as spend Black Matter on Special Upgrades and check your current Black Hole Travel stats.

Upgrades unlock as you perform more Black Hole Travels. Each time you perform a Black Hole Travel you will gain Black Matter that you can use to activate upgrades.

If you need help with the distribution of Black Matter and overall Black Hole progression visit the Black Hole Progression Guide.

Black Hole Upgrades

Black Hole Upgrades Tab

Black Hole Upgrades cost Black Matter and unlock upon performing more Black Hole Travels. Here you can spend your Black Matter to purchase various powerful progression upgrades.

Upon performing Black Hole Travel prestige (Tier 2 Prestige), you can refund 1 Black Matter Upgrade. You have to do this before killing 1000 enemies, so make sure to do it at the start of the run if you plan on refunding.

Some Black Hole Upgrade costs are decreased after performing Supernova Collapse (tier 3 Prestige).
