In this puzzle, you have to determine which field on the board should be white, and which should be black. On the left and top of the puzzle, you find numbers. These numbers tell you how many black squares there are on that row or column. There are grouped in undivided strings of black squares: if you find 2 5 4 on the row, that means there are (possibly) some white squares, then 2 black squares in a row, then some more white squares, then 5 black ones in a row, followed by more whites, 4 black squares, and possibly some trailing white ones. If you have all the black squares filled, the board displays an image. The title of the image gives a hint to what you are supposed to reveal.
Game PlayIn this game, all squares start out grey, indicating you have not yet detemined if they should be black or white. Click them once, and they turn black, click them again, and they turn white. A third click will put them back to grey. If you complete a vertical or horizontal string of black squares, you can click on the corresponding number in that row or column to grey it out. Click it again to turn it back to black if you change your mind. You can also download the puzzle in PDF here and play it on paper.
