Pokémon Picross (Japanese: ???????? Hepburn: Pokemon Pikurosu) is a freemium puzzle video game featuring Pokémon characters developed by Jupiter Corporation and published by Nintendo and The Pokémon Company for the Nintendo 3DS. The title is part of the "Picross" nonogram series that use number-based grid puzzles to reveal pictures. It was released as a downloadable title on the Nintendo 3DS eShop worldwide in December 2015. Pokémon Picross follows the typical format of nonogram puzzles in which players must use numbers depicted on a grid to determine which sections to fill and not fill in. In this a game a twist is added in which when a puzzle is completed players are rewarded with a Pokémon based on the puzzle they cleared. These Pokémon can be set before starting a puzzle and can utilise various abilities based on their type. For example Electric-type Pokémon can slow down the levels' timer while Fire-types can automatically fill in certain areas of the grid in a cross-shape pattern. Each Pokémon has a cooldown period after their ability is used and their ability may be limited to grids under a certain size anywhere from 10x10 to 20x15 (the smallest and largest Pokémon puzzle sizes respectively).
