It is so hard to collect gems for no reason. And when you do, the chests give you absolute nothing. For example I patiently gathered 380 gems in three months and when the "The frog Princess" chest was available, I spent all of them in the hope that with 6 chests, I would get plenty of characters. And all I got was CHAIRS. So, either you're kidding me or you take all the fun out of it purposefully. It's a shame and a pity.
