Checking
The objective is to find all of the Black squares. The system will check the grid when all of the squares are either Black or White. However, you can click 'check' at any time to see if you've correctly found all of the Black squares or simply to check your progress so far. If 'show mistakes when checking' is ticked / checked mistakes will be marked in red.
Uniqueness
This puzzle has exactly one correct answer, which can be found using logic and deduction alone, and no guesses are required. If you think that you have found another answer, then please check the rules carefully for a reason the other answer isn't allowed.
