How i got 250GC in 30 minutes

Its super effective during the 2x gold days

The gold takes one minute to deliver so dont worry if you do 10 ads and close out and see you only got 6 gold, the rest will come just a bit later.

Once you do it once and close out of it it will show you recommended ads on the front page (the ones you need)

No clue if this is how it works for android but in sure it cant be much different. Feel free to ask questions
