Research

Research is a way to unlock new Buildings and Resources in CivIdle. Moreover you can get access to some new Game Mechanics as you progress the game.

Research Introduction[edit | edit source]

Each run after Rebirth you will start with 4 basic Research unlocked and will need to go through the Research Tree to unlock everything again.

In order to unlock Research Technologies you will need Science.

When you research a technology of the new Age you will be rewarded with a choice of 3 random Great People of that age.

Some Research unlocks have Prerequisites that have to be researched before being unlocked.
