- Research lab boosters
- Trading booster - This booster boosts your currency selling price and trading capacity for a certain amount of time.
- Mining booster - This booster boosts your mining power on all rigs for a certain time.
- Paid boosters
- Cats and plants - These boosters are acquired with super-cash, and they boost mining power of a certain rig for a certain amount of time. You can place cats or plants on any rig you want, and you can see the boost amount in the side-bar, which is opened with the bottom left button in the footer.
Also worth mentioning, always try to use your Trading and Mining boosters at the same time, since they work excellent in synchronicity!
