Light Year
Light Year is one of the tabs in Galaxy Idle Clicker. It's being used to perform Tier 1 Prestige - Travel Back in Time and spend Light Years for various upgrades.
There are 3 available tabs in Light Years tab: Time Travel, Upgrades and Statistics.
Time Travel Tab[edit | edit source]
On the Time Travel you can see current Run Light Years gain, Next Black Hole progress and current multipliers.
Light Years Calculation[edit | edit source]
Your Light Years gain from the Current Run is being calculated from the multiple progression metrics from your current run:
- Planets Completed
- Levels Gained
- Upgrades
- Enemies Killed
- Army Created
And then sum of gained Light Years is multiplied by the Time you spent in the current run. Although Time Bonus isn't linear. The longer you stay in the current run, the lower multiplier gain you will get.
| Time Bonus Multiplier | Time Frame | Total Run Time |
|---|---|---|
| 5x | 0h-3h | 3 hours |
| 8x | 3h-7h | 10 hours |
| 10x | 10h-12h | 12 hours |
| 15x | 12h-20h | 20 hours |
| 20x | 20h-24h | 24 hours |
Light Years Multipliers[edit | edit source]
On the top of the Time Travel screen, you can see the Multipliers Gains that are awarded for Light Years from Time Travels Gained this run.
By default, you will get only Damage and Health Multipliers, but as you get more Light Years you will be able to unlock more stuff.
| Multiplier | Light Years to Unlock |
|---|---|
| Damage | 0 |
| HP | 0 |
| Junk | 3.5k |
| Plasma | 6k |
| Exp | 10k |
| Prisoners | 15k |
| Citizen | 22.5k |
| Garbage | 100k |
| Energy | 5m |
Travel Back in Time[edit | edit source]
Travel Back in Time button will perform Tier 1 Prestige for your current run. By prestiging you will get Light Years depending on your current progress and reset most of the progression systems in the game.
What gets reset on the Light Year Travel Back in Time Prestige:
Junk and Plasma Stored and Upgrades
Skill Points and level
Prisoners and Citizens and their Upgrades- Universe progression (Galaxies, Solar Systems, Planets and Areas)
Light Years Upgrades[edit | edit source]
After you perform Travel Back in Time you can spend your Light Years to purchase the upgrades. The path here is pretty linear, since you will need to unlock previous upgrades to get access to the new ones.

Infinite Light Years Upgrades[edit | edit source]
Infinite LY upgrades are available after finishing up Light Year upgrades and they will not reset on Black Hole Travel Prestige. However, they will reset on Supernova Collapse.
Most of the Light Year Infinite Upgrades will unlock as you progress through the Black Holes.
Once you get access to the Light Year Infinite Tab you can decide how to spread available light years. It's usually up to a personal preference, but make sure that you get Special Upgrades when you can afford them.
