FillDokuが完了したときに画像を形成するロジックパズルです
FillDoku is a logic puzzle that forms a picture when completed. It is similar to minesweeper - there's a grid with numbers as clues and you figure out which squares should be filled in.
This form of puzzle is sometimes known as Nurie, Nampre, Mosaik, Japanese Mosaic, Count and Darken, or Fill-a-Pix.
