Shop:
Blocks Building Clicker has a game shop, where you can buy some upgrades for your block. For example in the beginning all your blocks have 1 level, it means that when you tap only 1 block will be spawned, but if you upgrade some block to 2 levels, one tap will spawn 2 blocks.
Map:
Now you can see all buildings you create. Build/Click more and see how your city is growing.
Gem:
In this clicker, you gain 1 coin for each placed block, but you have a chance to gain a gem. If you have a gem, you can upgrade any block and do not be worried about the price. It's very simple, one gem equals one upgrade.
Levels:
Each level is a unique building. Some of the levels very small, but some contain more than 5000 blocks. Levels have certain order - it means that in the beginning, you will build easy levels, then medium, and then hard.
Hint:
Upgrades will help you to click faster.
