Cubic Tower is an awesome tower-building game that you need to stack blocks over each other to build a tower of immense size. There are blocks that don't affect any way, however there are some special character blocks , too, that are able to perform different tasks. Keep an eye out for them because they could both benefit as well as hinder your building! As you advance you earn coins and use them to purchase various blocks and characters. The game's gameplay is infinite, so you need to aim to get the highest height you can by building your tower. If it is destroyed, you need to begin from scratch! It's fun to try and build the most impressive Cubic Tower!
