Grid Cross

Grid Cross, like Nonogram, is a logic puzzle game that requires each square in the grid to be filled with either a black or white color according to the numbers at the side of the grid. The numbers, given for each column and row, show how many unbroken groups of black squares are in each column and row, as well as the number of black squares in each group formed. A group is separated by at least one white square in between. For example, the clue "4 1 2" means that there are three groups in that order, with four, one, and two black squares in the corresponding group, with at least one white square between the groups. There is only one possible solution for each game pattern.
