Tips and Strategies

  1. Do all the repeatables you can! 10 times XP and a postcard to buy equipment with is too good to ignore.
  2. Before the start of event, you can dig up all but 1 tile from each repeatable, especially during the double materials week.
  3. Also leave out 1 chest (preferably 1st gold) when you dig out your green ring mines during the double materials week. Collect that last one during this week for 10 times XP and postcard.
  4. You can skip the non-food material repeatables from your current region and some high cost mines like the ones giving jewels like ruby, topaz, sapphire, diamond, etc. if you don't want to spend a lot of energy for this week. (but tip #3 does apply! Just don't do it again)
  5. The 8 hour refreshing mines can be dug thrice and 12 hour ones twice each day, set your alarms!
  6. The 10 times XP and postcard also applies to repeatables in events, so if you have an ongoing event with a repeatable, make sure you dig that as well.
  7. In my opinion, buy the equipments with postcards (unless you're at par with what's being offered) and green rings with the remaining postcards.
  8. This week is probably the best use of a 168h speed potion since you'll have to dig a lot of tiles in a lot of mines (if over china).
