Touch the current tiles to rotate.
Drag and drop on the board to place.
The next tiles are shown next to the current tiles, in smaller size.
The goal is to fill all green areas with tiles, while leaving the red areas blank.
It does not matter whether the blue areas are empty or not.

Fill an entire line or column to erase that line.
By doing so, you can erase the tile parts in the red areas.
Filling and erasing some of the red areas are necessary in the later levels.
