Couldn't see that this was posted before, so ill go ahead a post it
The first thing you need to do is make a new email for free. Then go to the Recruit a Friend section and send the referral to your new email, go onto your new email and accept the free 10 day trial. Log into both accounts and make your main account follow your new account, then just play your new account like normal. Every 2 levels grant your main account a free level
When your free 10 day trial is up buy 1 month on that account. Don't worry, you don't need to pay extra for this - Because when that account buys 1 month, your main account gets 1 month for free! So its like getting a free month of play time Now all you need to do is repeat the following steps and go ahead leveling at x3 the speed!
Hope this helped, some might consider this as 'useless' or 'common sense'. Well, I only thought of this today, so some might not know it
PS: Doing this process and then buying 1 more month means you get a free rocket mount along with 70 days of a free account for just the price of 1 month
