Picross 3D is a puzzle video game developed by HAL Laboratory and published by Nintendo for the Nintendo DS.

While Picross presents a rectangular grid of squares, which must be filled in to create a picture, Picross 3D uses a rectangular prism made of a number of smaller cubes, and must be chipped away in order to construct an image in three dimensions. Each row or column has at most one number corresponding to it, and many do not have any numbers at all; the number indicates how many cubes the row/column should contain when the picture is complete. If a number has a circle around it, it means that, while that number of cubes is the total amount in the row/column, they will be split up into two groups (for example, a 4 with a circle around it will be in two groups of either 1 and 3 or 2 and 2). If a number has a square around it, the cubes will be split up into three or more groups. If there are no numbers on a row or column, there are no rules concerning how many cubes belong there.
