Place buildings on the board and merge together groups of three to create larger sized buildings in City Blocks! Grow the population of your city by growing the buildings. Each game starts with a few random buildings placed on the 5x5 board. Place buildings by tapping empty squares. The next building types in line are shown in the bottom left. Place three of the same type building to merge them together into a larger building, which will grow the population of your city. The smallest buildings grow the population by 4, and is doubled with each upgrade. Jokers will appear randomly from time to time, use them to swap the next building with the building of your choice. The larger the building, the more jokers you will need to collect. When there is no space left on the board to place a building, the game is over.
