In this game you're looking for the treasure hidden on the uninhabited island. The most interesting part of this game is interactive buildings and bonus levels.
Bonus Match 3 levels are more tricky than the regular gameplay. Bonus levels are optional, so you can skip them if you don't like too much challenge. Bonus levels are passable in Relaxed, Timed and Moves Limited modes. They all are replayable, so if you can't complete it, you can replay it later.

Also you have the Notepad. Notepad tells you how to find treasures. There are some "interactive" buildings, for example, if you click on the cannon, it will fire.
To reveal a treasure, you should activate buildings in a sequence that described in the notepad.

In addition there are some Spot The Difference scenes.
