In the game's main Picross Mode players must reveal a hidden image that lies
beneath the puzzle by filling in a grid with squares and crosses to complete
patterns. Variety is the spice of life and Picross DS does not disappoint with a
staggering 300 puzzles available to play at your leisure. These games range from
the elementary five by five grids, to highly complicated twenty by twenty grids
which will keep even the most hardened gamer happy. Finishing all these
challenges will keep you busy for weeks. There is no need to worry if you get
stuck by one of the more devious challenges as you can opt to receive clues to
help finish puzzles as well as give yourself a head start with a roulette style
hint function that reveals one line of the puzzle.
