There are a few ways to get gold in Gardens of Time. By far the easiest way is to simply pay for the gold yourself, using real money - obviously this isn't for everyone though!

In terms of free gold, you get some every time you level up (as well as a full energy bar).

You can also earn some from clicking the 'Earn Gold' option of the 'Get Gold' tab - normally this involves completing surveys or making the most of certain offers.

Anywhere unofficial that claims to offer free gold could result in your account being suspended or banned.
