->''"Hi, Kids!! It's time for us to solve the mystery of 'Picross'!"''
-->-- '''Mario'''

In this picture puzzle game for the GameBoy, the player helps [[Franchise/SuperMarioBros Mario]] discover hidden pictures by filling in blocks in a grid. The numbers along the top and left side of the grid provide clues as to which blocks should be filled in.

The puzzles in this game are just like [[http://www.conceptispuzzles.com/index.aspx?uri=puzzle/pic-a-pix Conceptis' Pic-a-Pix puzzles]], and are also called [[http://en.wikipedia.org/wiki/Nonogram nonograms and other names]].

The games in the overall ''Picross'' series are:
* ''Mario's Picross'' (1995, GameBoy)
* ''Mario's Super Picross'' (1995, {{SNES}}, JP only[[note]]The game was eventually released as part of the Wii and Wii U's Virtual Console service, but the original SNES version is Japan-exclusive[[/note]])
* ''Picross 2'' (JP only, GameBoy)
* ''Picross NP'' (eight volumes for the "Nintendo Power Super Famicom Cartridge Writer", a rewritable {{SNES}} cart; JP only)
* ''Picross DS'' (2007, NintendoDS)
* ''Picross 3D'' (2009 JP/2010 US and EU, NintendoDS)
* ''Picross-e'' series (six downloadable installments for Nintendo3DS)
!!Tropes Used in Mario's Picross:
* ConsoleCameo: Both ''Mario's Picross'' and ''DS'' include puzzles of Nintendo systems (''Mario's'' just has one of the GameBoy, ''DS'' has a whole series of them).
* GridPuzzle: A given since the game is basically solving nonograms.
* NintendoHard: Some of the puzzles in all games can get pretty brutal, and require more than a little guesswork to solve. It doesn't help that in ''Mario's Super Picross'', some of the puzzles were changed for the Virtual Console version, which means that walkthroughs may not be accurate.
* OddballInTheSeries: ''3D'', since the execution of such puzzles in three dimensions is so different.
* OldSaveBonus: Some of the later ''Picross e'' games unlock new puzzles or sets of puzzles if you have save data of the earlier games.
* {{Portmanteau}}: Picross = picture crossword.
* SpiritualSuccessor: As of ''DS'', Nintendo has dropped the Mario branding, but that game had ''Mario's Picross'' level packs available for download.
* TimeTrial: Completing the Star course in ''Mario's Picross'' unlocks time trial mode, where you solve a random picross as quickly as possible. In this mode, you have unlimited time, but mistakes aren't revealed. In ''Mario's Super Picross'', Wario has an entire set of puzzles like this, unlocked after you beat the first level of Mario's own set of puzzles.
