Summary: I have played lots of puzzle games and this is the only one I've played multiple times. I also have picos 3D, which is ok, but I like the bigger, more complicated puzzles that the 3D version doesn't have. Highly recommended if you enjoy mind puzzler games like sudoku and some of the Professor Layton game puzzles.
Summary: It really is. Picross is super simple. There are a ton of puzzles in this game and there's some daily Picross thing to keep you coming back for some speed challenges. If you like Picross, then just buy this because it's so far the best Picross game I've played.
Summary: I bought this because I love picross 3d and was not disappointed. It is very challenging at times. The only drawback is that the puzzles are very small for the screen and I found I made mistakes because of that.
Summary: The many who got started on Sudoku puzzles, would have found that the logic game of numbers makes them play the game over and over. Then, there are also many artists who like doodling on Internet oekaki boards - places where you can make small, pixel drawings to share with the world. Bring both of them together and you get Picross, a logic puzzle that combines pixel drawing elements.
Summary: I am a Picross fanatic. As such, I've played just about every picross variation on every console/medium possible. Out of all of these games, I have to honestly say that Picross DS is one of the best I've ever played. - The Puzzles - The puzzles are pretty much standard Picross fare - which isn't to say they're boring! If you enjoy picross/nonogram puzzles, you'll love these.
Summary: PICROSS is an incredibly addicting DS game. I have spent many a nights playing puzzle after puzzle. While I find "easy" mode too easy, "normal" mode went from moderate to hard for me. The mode after that I suspect will be quite difficult since there are no hints and it doesn't tell you if you've made a mistake. The game is laid out nicely so you build from easy to hard.
Summary: This game is awesome. It is my favorite puzzle game for the DS or any other game system. It seems difficult at first if you have never tried this type of puzzle before, but it is easy to get the hang of and then is very hard to put down. This is an awesome game to get your kids as a mentally challenging and stimulating alternate to other video games.
