Picross DS (Nintendo DS)

Like finding the underlining 'picture' in a 'crossword puzzle', the goal in Picross DS is to fill a grid with squares and crosses in order to 'paint' a picture. Numbers at the head of the puzzles' columns and rows signify how the grids need to be filled out, but it will take a sharp mind to figure out the solution - and some speedy fingers to defeat the competition. The game's main Picross Mode offers a staggering 300 puzzles available to play at your leisure.
