Available only through March 4th- March 27th
This is an event that leaked from one of the players that was invited. The winner was supposed to go to this site and get his G-coins doubled. They invited 20 people and who ever had the most G-coins in a week would have the chance to have them doubled. (If you ask me its just the admins trying to get people to buy G-coins) Well the link leaked. Heres the link, Log in and if you have any G-coins they get doubled in like 2-7 hours.. Something Like that, Might be longer took me 10 minutes. 20 G coins FTW!! LINK BELOW!!
This is an image from the G coin event they threw last year:
