I saved a lot of gems but still not sure where to use them. That's all I could remember now, but if anyone can offer something what only gems can do and something what will affect the gameplay in a long run (and not just for sake of unlocking something), I would like to know what else I could use them for. Using it for the Tribe race when it makes a difference (getting higher place) or getting the next chest which will grant those gems back anyway. Upgrading Zeppelin Harbor to elite to transfer the resources which are produced only on special islands and are needed in big amount on the other islands. Game Support credited me the 18 gems to buy the fruit quest. Upgrading Buildings that I use often and which I use for the competition to elite. I contacted Game Support and submitted a screenshot (as I cut down all my trees and never got the fifth fruit). So, I focus on the things which cannot be done with other than gems resourses. And lvling silkworm farm only to lvl 4, choosing the right lvl of the market depending on your avaliable resources. Like not lvling fishing hut and ostrich farm, because if you lvl them while not having fishing and farming kits you slow yourself down so hard. But even farmer's bayisn''t that slow if you play it right.

I feel like the point of the game is slow progress. For me things that can be done with other resources don't need gems even if it's slow progress.
