Here we see the default puzzle in its initial state:

Since the first and last columns as well as the first and last rows are shown as having 15 cells filled in, we can mark those entire rows colored.

Rows
Let's start by looking at row 2 next. In this row we are told that there are 7 consecutive colored cells followed by one or more blank cells followed by 7 more colored cells. Since this row starts end ends with colored cells, we can color in from the sides and also mark the cells between those two colored ranges as blank.

In rows 3, 4, 5, 6, 8, 9 and 11 we also see that there are two groups of colored cells, and can repeat the above tactic again.

In rows 7 and 14 we know that they begin and end with a single colored cell, and since those are already colored in, we know that the cells next to them must be left blank.

In rows 10, 12 and 13 we again know how they begin and end, and even though we have no way of positioning the colored cells between those we can color the beginning and ending ranges as well as the blank that must be next to them.

Columns
Looking at columns 2 and 14 we see that all ranges specified have been colored, so any remaining unknown cells can be set to blank.

In columns 4, 5, 6, 7, 8, 9, 10, 11 and 12 we can color several of the cells starting from the bottom of the grid because we know how long the ending range of colored cell will be. We can also set the cell above that range to be blank.

From here to the end, it is a matter of looking at the row and column values as we have been and completing the puzzle.

This puzzle is the default puzzle for the program (C01_P01) and will appear when you launch the game for the first time. After solving the puzzle, you can go to the Game menu and select Check to confirm that you have solved it correctly.

Good luck and have fun!
