This is the demo version of Novendah, there are only 20 levels available. The full version features 40 levels. The goal is to align at least 3 blocks of matching colours to remove a row. For every removed block and row you will get points. You have to fill the score meter before you run out of time. There are also "Wild Tiles" and brick wall blocks than can hinder or help you as bonus levels and a hidden super bonus level which you have to unlock.
