Update: i borrowed an old iphone 6s to try the link for free coins. I wouldn't say this isn't luck based but compared to the other slots offered I've played( and i played a LOT) the chances of completing this one is higher. After a few hours, just click on chat and I'm always able to collect a few million coins. Joining a good active club helps out a lot. If links are not yet expired, should give you 100mil, i also collected the in-game hourly bonus, chest spin bonus and highland garden club bonus. Always made sure that my dragon was fully fed to increase chances of triggering 'dragon respin'.
Played mother of dragons slots and just let it run while i sleep.
