Your aim in these puzzles is to colour the whole grid in to red ball and clear blue ball. At the top of each column, and at the side of each row, you will notice a set of one or more numbers. These numbers tell you the runs of red balls in that row/column. So, if you see '10 1', that tells you that there will be a run of exactly 10 red balls, followed by one or more blank cell, followed by a single red ball. There may be more red balls before/after this sequence.
