Gems

How do u get gems easily

You need to clear your village of all the stones and trees. Mine has 0 trash in it. Got 50-60 gems from it all... Costs a few hundered K but is worth it.

But do you want to get them easily? Oh u just have to go to shop>treasure>chest of gems>confirm purchase

without spending money the (relatively) easy gems are in the trophy based achievements. Go visit the crystal league - it is not that hard.
