Nintendo have published several nonogram video games using the name "Picross" (ピクロス, Pikurosu). The Nintendo Game Boy game Mario's Picross was initially released in Japan on March 14, 1995 as part of the NP Picross series to decent success. However, the game failed to become a hit in the U. S. market, despite a heavy advertising campaign by Nintendo. The game is of an escalating difficulty, with successive puzzle levels containing larger puzzles. Each puzzle has a limited amount of time to be cleared. Hints (line clears) may be requested at a time penalty, and mistakes made earn time penalties as well (the amount increasing for each mistake). Picross 2 was released later for Game Boy and Mario's Super Picross for the Super Famicom, neither of which were translated for the U. S. market (Mario's Super Picross was, however, later released on the Wii Virtual Console's PAL service on September 14, 2007, as part of its Hanabi Festival). Both games introduced Wario's Picross as well, featuring Mario's nemesis in the role. These rounds vary by removing the hint function, and mistakes are not penalized—at the price that mistakes are not even revealed. These rounds can only be cleared when all correct boxes are marked, with no mistakes. The time limit was also removed. Nintendo also released eight Picross volumes on the Japanese Nintendo Power peripheral in Japan, each with a new set of puzzles, including puzzles based around various Nintendo characters, such as Mario, The Legend of Zelda, and Pokémon.
