Best Way To Get Gems

So you wanna get gems but dont know where to start
first thing you do is SHUT DOWN YOUR PC and download the mobile version
then log into your account then you can watch the gem videos anywhere thats ten gems every hour PROFIT
step 2 grind achievments they give you anywhere from 50-200 gems
step 3 log in everyday you get 50 gems every 5 days thats 300 gems a month
do these for a while and you should slowly start to get loads of gems i mean if you watch the ads thats 240 gems a day soooooooooooo
i figured out if you do every ad and log in every day thats 7500 gems (i think) so you can get every expansion in a month if you dont enjoy sleep
that is the best but a very slow way to get gems
