The concept is simple: you’re given a row of cubes that seemingly form a simple shape. But etch away specific cubes and you start to reveal a hidden picture. That’s it. That’s the entire setup for Picross 3D, a puzzle game for the Nintendo DS released in 2010. With the perfect blend of easy and difficult, fun and challenging, and simply addictive nature, Picross 3D is one of the best puzzle games on the DS, and one of the best puzzle games to come out this side of Tetris.
