Get all of the neighbors you can Cheats & Tricks
The old saying "the more the merrier" works here just like in any Facebook game. You want to have as many neighbors as possible to get ahead in Treasure Isle. Why? Because you can visit their islands daily and gain coins and experience by helping them do a task, collect coins from their floating treasure chests, and collect gems from their trees. This is a must if you want to get past all of the different large Tiki heads that require 5 or more of one color gem.
