2. Picross 3D
Taking its cues from the original Picross, which had players shading in Sudoku-esque number grid puzzles to form pictures, Picross 3D has more in common with sculpting than pixel art. Each piece of 3D art begins life as a cube covered in numbers that represent the number of blocks in any given row or column the finished piece will contain. Using a little deductive reasoning and logic to make sure the numbers between grid and row match (and with the help of a marker that lets you tag blocks you want to keep) youâ€™re free to chip away at an unfinished cube until a shape appears. Needless to say, this is great fun for fans of spatial puzzles.
