Age of Emerald 

Age of Emerald is a puzzle game made by Rumbic Studio. The game is a connect-three puzzle game. You get several objects of different types on top of tiles, and you must use your mouse and drag objects to connect three or more of the same type. With each match you gain gold, food and other points. If the object has a marble tile behind it, this allows you to earn more resources.

So far it sounds simple enough, but these resources are for a reason. You must build a city from scratch using these resources. You have to plan on services and food for the inhabitants as well as what type of building you have to build next. There are around 30 buildings and the more resources you win, the bigger your city will be. This does add a little bit more distraction to the game, although it does not really do anything else but to give you an objective. The puzzles are well made and will keep you entertained for a while. This is a good connect-three game but still, it is only for fans of this kind of games.
