This tenth and final puzzle is even larger than the other ones, and shows yet another of the activities here in the workshop. Beware, it's a big one so it may take a while to solve!
To complete the puzzle, use the mouse to click left for a black square, right for a white. Click again to clear any mistakes. You can also click and drag to fill in a row or column with either squares or dots. As you complete each row and column, green or red indicators will light up to let you know whether it matches the clue or not. A green light doesn't necessarily mean it's correct, but it does mean that the number of squares matches the clue. To make the display as big as possible, just maximize your browser window or use full-screen viewing mode.
This is the last of the puzzles here at the activityworkshop, so if you've completed them all, feel free to look around for the other types of puzzles and games here.
