In the past, the newest and most complex islands had the most players. In June 2009, by all reports, the new Astro Knights Island had the most players.
However, in terms of sheer numbers, more players have played Great Pumpkin Island than any of the others, probably because it was easy enough for anyone to grasp. The number of Island Medallions won, however, was about the same.

there is no lapso island on poptropica
Nabooti Island and Time Tangled would be my opinion.
Vampire's curse is the most recent island.
As of its release date of January 17, 2011, the most recent island was #16 - Cryptids Island.
There is no Candy Island on Poptropica. There is no known plan for a Candy island on Poptropica.
Poptropica Island is already unlocked.
Probably the most difficult island on poptropica is the latest one, Skullduggery. However, it is a matter of opinion. Besides Skullduggery , thay are pretty much the same.=)
The 6th island in Poptropica was Spy Island.
