How to Restart the 1 Gem Boost for 7 More Days

Step 1
The first step is starting an upgrade on a Mine, Collector, or Drill you want to boost again. DO NOT upgrade a boosted Mine, Collector or Drill! This will causes the boost to end. The 1 Gem boost ends the morning of August 7th.

Step 2
The next step is canceling an upgrade. Although canceling an upgrade only gives you back 50% of the cost. For example, canceling a level 10 Gold costs 84,000 Elixir.

Now that the boost is canceled and you’ve canceled the upgrade, you can now restart the boost for another 7 full days.


If you do this process for each Gold Mine, you’ll make a profit of up to 5,292,000 Gold (depending on how many Gold Mines you have). Don’t forget this is also possible to do for Elixir Collectors and Dark Elixir Drills, so the total available profit is over 1 Billion in resources.
