Use your imagination and fast reaction to join together similar blocks to make them disappear and lower the sky line. You start by being able to rotate 2 tiles at a time being your initial mission to match together 3 similar blocks. As the game progresses, so will your strategy, as you need to adapt to the play mode defined in each new level. Pay attention to the instructions at the beginning of each level as you will have to rotate 2, then 4, then 5, and then 6 at the higher level, and make increasingly longer vertical or horizontal lines as the buildings rise from the ground and the free space is less and less.
In the end you will conquer the sky and become a Towers champion!
