Permanent Boosts in the Shop
Permanent Boosts are Boosts that never run out and therefore provide a permanent upgrade to the income in your mines. They can be bought in the in-game Shop for real money.
- 2x Idle Cash forever (this can be bought twice and stacks to 4x)
- 2x Cash forever
- No Ads Offer (Provides a permanent Ad Boost that has to be extended manually)
Adding friends also provides your game with a permanent 100% income increase, but this cannot be directly observed in the boost of your mine. The friend boost will double your Income Factor that determines how productive your mine is!
