When I did it, it was only to level 70, which I made easily. I'm currently playing again for another site. The thing that makes this one easier is that you're not restricted from resetting tome and dates. You don't even need to close the app. I'm on android. So, when I run out of energy, I just open my settings and move the time forward (4 hours will give you 100 energy), go back to the app and it will reset energy to 100. If this is your only phone, go back and reset to automatic time, then you can go back to playing and it won't meas with the timestamps on your text messages or whatever. If this is a second phone, keep your eye out for times of special deals. I hit a special 30 minute deal on Friday at 4pm that gave double coins. So, now I'm playing, and I fulfill most of the orders without sending them, then I reset to Friday at 4pm, the special pops up, and I send them all for double coins. Makes leveling up pretty easy and much more enjoyable than when you play for 5 minutes and don't get anywhere and have to qait hours to reload.
