(Japanese: ポケモンピクロス Pokémon Picross) is an unreleased puzzle game for the Game Boy and Game Boy Color announced in various game magazines in Spring 1999. A picross, from picture and crossword, is a genre of puzzle games, also known as a nonogram. It was developed by Jupiter Corporation.
The player must complete all of the picross puzzles in each world. Completed levels will be marked with Pokéballs; if the puzzle is finished in a select amount of time, it will be marked with a Master Ball instead. Pikachu appears in the top-left corner of the screen, cheering the player on; along the way, more Pokémon are "captured" and can be selected (Bulbasaur, Charmander, Squirtle, Jigglypuff, and Clefairy). There is also a tutorial mode with easier puzzles, which is guided by Misty.
