Supercel's Birthday gift

taken from "http://www.clashofclanstactics.com"

Clash of Clans is one year old! You can now boost all your resource collectors for ONE WEEK for only one GEM each until August 9th!

Look at you Inbox for details. Yes, it's official announcement from Supercell!

Wow! Look at that, only 1 gem to boost the Dark Elixir Drill for 7 days. Sign me up!!!

There is no other time better than this anniversary to spend your Gems!

Simple math here: Dark Elixir Drill level 6 with 100 Dark Elixir production per hour, you will get additional of 100 x 24 x 7 = 16,800 Dark Elixir for the cost of only 1 gem!!!

Gold Mine level 11 with 3,000 Gold production per hour, you will get additional of 3,000 x 24 x 7 = 504,000 Gold for the cost of only 1 gem!!! 6 Boosted Gold Mines mean 3 million Gold!

Tactical Analysis
For those who want to farm a lot of Resource, it's time to carry a bunch of Goblins in your army. Your Goblins will be very busy stealing those Resource from the collectors with green glowing light around them.
