One major problem I was facing in Treasure Isle, having a small number of neighbors, was gems-related and I always had trouble with the Purple Gems specifically. Fortunately, starting today Zynga has made some changes to Treasure Isle and now every player can gift any type of gem.
This means that now you can choose to send your Treasure Isle friends (and they can do the same) any of the following gems: Green Gem, Red Gem, Purple Gem, Orange Gem. And hopefully this will bring an end to our (or at least my) gem-related problems in the game.
And also, if you are still building the pirate ship, all the parts required to build it are available as free gifts. I just hope that this is a permanent feature and not a simple error from Zynga.
What do you think about the possibility to send any type of gem to your fellow treasure hunters?
