Copy the picture into paint, I fill the correct squares in red, and put a black dot in all the squares I know are not red. It is important to note that the picture is mirrored left to right, so all your actions will be mirrored. If the second square from the left is red, then the second from the right is red. The two outside coulmns have 0's so you know none of them are red, put a black dot in them. Go to the 6th row from the bottom, it has six 1's. If you skip the first column (since that's got a black dot) and then fill every other box you'll end with three empty columns at the end. That is not mirrored, but if you move them all over 1 block it is symetrical.

The line right below it (121121) has only one solution that will fit. Once you fill that it you can start looking at the column numbers. For instance you should see that you have 1 filled in square in the in second column and second to last and each is labeled with a 2, that means that either the box above or below the one you already have should be red. You don't know which it is yet, but you do know that none of the other boxes in those columns will be red, put black dots in all of those, eliminating them as possibilities for the other rows. You just have to keep doing this, it's as much about figuring out which ones aren't filled as which ones are.

Finally your answer will be 3 words
