Overview

About this game

Create stars, build constellations and expand throughout the space void in this scifi-themed idle game. 'Cause yeah: in the purest clicker tradition, Light 'Em is all about gathering star energy... to keep on making more!

  • Unlock new star types and features or just watch your stellar empire thrive

  • Discover the real 80+ constellations or invent your very own

  • Unlock exclusive features via the skill tree, like the Galactic Market or the Space Casino!

  • And reboot the whole universe to continue your journey...

So - ready to dive in, astronomer?

Discover real-life constellations...

Ever wanted to learn the shapes of the night sky? With Light 'Em, you'll get to explore and learn the 80+ official constellations at your own pace - while learning the most common stories behind each one!

All the constellations you've discovered will be stored in your Codex - so: can you get them all?

... or make up your own!

Light 'Em will also allow you to draw your very own constellations! If your current star group exceeds some (upgradable) thresholds but doesn't match the shape of a real constellation, then it will auto-validate with an arbitrary name. But don't worry: you can also rename it to your liking :)

Boost your astronomer skills

Feeling stuck, and unsure how to find new constellations or get more stellar energy? Don't forget that rebooting gives you access to the skill tree, where you can buy new talents to progress further and faster...
