PUZZLE TYPES

 * Pic-a-Pix (also called Picross, Nonogram, Griddlers, Hanjie): What is mainly covered in this wiki. More info on this Wikipedia article.
 * 3D Picross: The 3D variant, which there a voxel-based shape is extracted from a plain block, by removing the useless blocks. First used in Picross 3D, there is also a handful of them on the smartphones.
 * Color Pic-a-Pix: The colored variant, which made the puzzles harder by adding the possibility of two or more different colors being adjacent to each other, without any clear spaces. There is a handful of them on DS and mobile phones, too.
 * Link-a-Pix: Here, the numbered dots should be linked together with a total distance equal to their number. Video games featured by Conceptis on PC/smartphones, Lightwood on 3DS and in the puzzle compilations.
 * Fill-a-Pix: It's much like Minesweeper, but with a picture puzzle, and no penalty for choosing bombs :) The numbered squares show how many squares adjacent to them (including themselves) should be filled in. There is SquareCells on Steam, and the Conceptis ones.
 * Block-a-Pix: Here, the grid should be divided only into the rectangular portions. Video games featured by Conceptis on PC/smartphones and Lightwood on Switch.
 * Maze-a-Pix: It's mainly a maze puzzle, and the solution makes a picture. Its most recognized video game featuring is the Picdun (Dot Runner) series for DSi/3DS.
 * Sym-a-Pix: Here, the grid should be divided only into the symmetric portions. Video game featured by Conceptis.
 * Cross-a-Pix: Here, the grid is divided to several cells, and the squares should be filled according to the numbers on the side, with the "all or none" rule on the cells -- a cell should be either fully blank, or fully filled. Video game featured by Conceptis
 * Patch-a-Pix: This puzzle consists of "block pieces" that should patched in the grid. First used in the minigame "Patchwork" in Game & Wario, this puzzle made its way to the smartphones, under the name Block Puzzle. (NOTE: The name Patch-a-Pix is not coined by Conceptis and is completely conjectural.)
