Event: Candy Mine |
At first: It works best if you can keep the game running all the time. That way, you'll be guaranteed of the best possible income and have the most efficient way of upgrading.
Income Boosts: The first tip is to use Income Boosts. They will give you greater amounts of cash to spend on upgrading your mines, elevator and storage. Try to combine it with the video bonus as well to get an even bigger bonus. If you are a daily player, you might have received a couple of them already by the daily login bonus.
Start first with getting all mines: The wisest thing is to get all the mines to your use. That does take some time (Couple of hours, mostly depending on how fast the unlocking of the new floors will be), but will make it easier later on. As you will have to wait for the mine upgrades after each 5 levels, you have some time to upgrade your existing mines for an even better income per mine. But keep in mind: You'll need a good amount of money for getting new mines to use.
Directors: If you can, get at least 1 director for the elevator and storage (Preferably 2 or even 3, so you can switch between them while cooling-down the other(s)). You can do this after you have most of the mines: That brings in a lot of cash which you can spend on hiring new staff.
Work from top to bottom: After you have unlocked each mine (So you have reached the bottom mine, level 30), the best thing is to start upgrading mines to their maximum one-by-one. Each mine can go to a maximum of 800 levels. Wisest strategy is to start by upgrading mine 1 to it's maximum, followed by the elevator/shaft and storage. After completing mine 1, continue with mine 2 and so on until you have reached you have finished all the mines.
