The latest title in Nintendo’s Touch! Generations series, Picross DS offers the ultimate in light puzzle entertainment. 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.
