Generally speaking each Machine should be upgraded as many times as possible once first unlocked. Instead you’ll be spending your clicks upgrading machines. Machinesįor lack of an ingame term, Machines are your income producers, and they all (as of the latest update) generate materials idly instead of by clicking a lot. For this reason it can help a lot to leave the game open on your phone while doing something else and check in every 5-20 minutes depending on how long before your next Resource goal. Resources are only generated while the app is open. Each Machine displays it’s per-second Earning rate, and Resources are all generated per-second rather than by tapping like in many other games. The Dig Unit is where most of the game is played, and Machines gather Resources for you every second.
