Research
The research tree and every bonus it gives your zoo for good.
🔬 How research works
At level 10 you can build a Research building (Buildings, Zoo page). Press it to open the research tree. Each project you finish gives your zoo a bonus for good.
- The tree has 3 branches. Each starts with one project, splits into two paths and joins again at a big final project that needs both paths.
- A project costs money and takes real time. It keeps going while the game is closed, and Zoo Tokens can finish it right away.
- You research one project at a time, or two once you have Second Lab.
