## How to play

This is an example of a completed Star Battle puzzle. The aim of this particular Star Battle puzzle is to insert one star in to every row, column, and region. Stars can't be adjacent horizontally, vertically or diagonally.
This is another example of a completed Star Battle puzzle. This puzzle is a little bigger, which means we need to insert two stars in to every row, column and region. None of the stars can be adjacent horizontally, vertically or diagonally (even those in the same row/column/region).
This is an example of a starting Star Battle puzzle. Our aim at the start of the puzzle is to pick out cells where we can't insert a star.
In this puzzle we have two regions that are a single cell in height - these are highlighted. We know that these regions must contain a star, which means that none of the other cells in these rows can contain stars. We can mark this by inserting a dot.
We now need to start looking at individual cells. If we were to insert a star in cell 'A', then that would mean that we wouldn't be able to insert a star in cells 'B', 'C', or 'D'. This would mean we would have no more free cells in that region to insert a star, i.e. a contradiction. This means that cell 'A' can't be a star, and we can insert a dot in cell 'A'.
This also means that cell 'E' must be a star - it is the only free cell left in that region. We will mark the surrounding cells with a dot since we can't have two stars adjacent horizontally, vertically or diagonally. Since we can only have one star in each row/column, we will also mark the cells in the same row and column with a dot.
Now that we have done that, we can see there are another two regions that only have a single cell available. We will insert a star in these cells, and mark the surrounding cells and the other cells in the same row/coumn with a dot.
