Welcome to part two of the Pocket Mine guide to getting more money and rubies! Click here to go back to part one of the guide.
One of the best ways to get free rubies and cash is to first, hook the game up to Facebook and/or Game Center. Invite people on either platform, and when they accept your invite, you will get a reward for inviting them. Usually, the reward will be cash or rubies, though sometimes it will be crates and keys. You can find the invite area on the fourth tab from the left in the main page.
Game Center is full of random people and they all play iPhone games, so that one is a good starting point for invites. For Facebook, send invites to your friends who you know are into iPhone games, and if you don’t have any, start a secondary Facebook account and start finding people who play other games. Then, add them, then send them invites to Pocket Mine, and reap the rewards when they accept your invite.
Different rocks are worth different amounts of coins in Pocket Mine. Coal, which is the black rock in the game, is worth one each. Gold, which is the (duh) gold rock, is worth two cash each. You get three cash for every Iron that you pick up (that’s the silver rock), while diamonds are worth five cash each.
Break as many crates as you can, because they will either contain big clusters of stones, or they will contain a collection artifact. Collection artifacts are worth between ten and fifteen coins apiece. After you finish a round, tap on the “Details” button under the amount of cash that you collected in order to figure out what artifact was worth how much cash, and to see how many of each of the stones that you got.
Tap on any stone that you see where the stones are surrounded by an orange glow. These are an explosive stone, and they’ll blow up chains of other stone blocks, causing you to earn WAY more cash.
Also, conserve your cash by not respinning after you get your cards. Keep the free cards that you get at the beginning of the round – all of them are advantageous to getting more cash, and respinning will wipe out any gains that you get, unless you go extremely far in a round.
