Lucky coins exploit
Since the forced update took care of all the cheating related to this exploit, by now it doesn't hurt anymore to share the public secret to harvesting lucky coins.
Several of these type of exploits (continuous GP rolls, daily set items, replaying golden clouds, etc.) are already covered in detail in several topics. Some of these exploits have already been fixed and some are still working.
This specific one however was different since it caused the objectives in the arena to reset as well. This was a poorly kept secret since there have been quite a few misguided attempts to share this information on this forum to "level the playing field". The method is also explained in detail on youtube.
In this forum, it has been extensively moderated to prevent more cheating in the arena. For this reason, only some of us have been able to harvest lucky coins in pretty large quantities over the last few months. We all assumed this would stop with the latest update, but although the cheating with this exploit did, the exploit itself is still working.
Some of you may remember the exploit where
changing the clock one day forward would trigger the golden clouds fight. Although this was fixed at some point, Rovio did not do a really good job at fixing this. Changing the clock itself may not work anymore, but changing the timezone does.
If you change only the timezone in such a way that you end up close to any midnight, you'll see the golden cloud appearing again.
As long as your last golden clouds fight was longer ago than the time after your new midnight, it will appear. After each fight, change the time zone again so you end up before midnight and you just wait until the midnight passes again. Since there's about 30 different timezones, including some with half hour of even 15 minute offsets, you can do this about 30 times per day (if you don't sleep of course!).
This has been confirmed for all platforms.
I am sincerely hoping that this post doesn't get moderated anymore and everyone can enjoy some additional lucky coins. We all agree that Rovio was a bit cheap with the compensations for all the mess-ups, but let's give them some credits for leaving this one open for all.
Happy harvesting!
