Hey I found a glitch to get unlimited gold.

To do this glitch, you first need to be offline. Then play normally until you get a "Watch an ad to get 150 coins". Then go in the shop and spamclick the ads to get free coins.

I hope it will be useful for many people.

Cool! Doesn't work on my Samsung S7, but maybe other phones will have this feature :)

In my phone never appears the watch an add featore when i'm online

Sorry for you ;D
