About Marupeke A Marupeke puzzle is made up of a square grid with crossword-style blackouts in some of the squares. An X or an O can be found in a few of the remaining squares. In order to complete this problem, an X or an O must be placed in each of the remaining squares while making sure that there are never three Xs or three Os adjacent to one another, either horizontally, vertically, or diagonally.
