City Blocks is a logical puzzle game where you will be connecting 3 buildings of the same type in order to build a new, larger building. You can continue to do so for as long as you have space to build these buildings, because once you start running low on real estate, the game will get much more difficult. You receive a Joker during the game that can help you out in this situation. It can be used to buy a building of a specific type that you need to combine with 2 others in order to free some space. The larger your city will become, the higher your score will get, so be sure to aim high.
