Ok, if you are one of those 60 millions people who enjoyed playing FarmVille (blame FaceBook and Zynga for making you crazy about this game), of course you know that when you visited your neighbors’ farms you’ll be offered to help them to get the rid out of some rats, and to do so, you just need to click an “OK” button on the offer popped up window, and you’ll received some bunch of experience points to level up along with some little amount of money.
Sure gaining experience points and money that way is easy. Perhaps one of the easiest. Rather than doing plant, and plow it as soon as possible (besides, its a waste of money). However, you can do it once in every 24 hours per neighbors. Sure you might have 2,916 neighbors, but still, it’s tiring to keep on visiting them one-by-one, moving your cursors up and down, clicking the “OK” buttons, and waiting for the application to load every time you move from one farms to another.
But what happen if you just taking an advantage over that loading time? Yup, the one that will happen every time you clicked on someone else’s farms? Hmm, this is what will happen:
First, click on the neighbor you’re willing to visit.
Straight away after you click the visit button, click that neighbor’s picture once again (must click the same person you’ve visited) – so that you can visit her again, even when the offer window opened already.
it seems it works everywhere not only on facebook.
well you can do it to your friends thought, i bet he/she will get a headache in no time
