Nintendo has released "Picross DS" for the Nintendo DS portable system in 2007. It contains several stages of varying difficulty, from 5x5 grids to 25x20 grids. Normal mode tells players if they made an error (with a time penalty) and free mode does not. A hint is available before starting the puzzle in all modes; the game reveals a complete row and column at random. Additional puzzles were available through Nintendo Wi-Fi Connection; some of the original Mario Picross puzzles were available. However, the service was shut down on 20 May 2014. Nintendo made new releases available bi-weekly. "Picross DS" was released in Europe and Australia on 11 May 2007 and in the United States on July 30, 2007 and has been received well by critics, including Craig Harris, Jessica Wadleigh and Dave McCarthy labelling the game "Addictive". A 3D version of the game, titled "Picross 3D", was also released for the DS in Japan in 2009 and internationally in 2010. A sequel, "", was released for the Nintendo 3DS in 2015. Another downloadable version of the game was released for Nintendo 3DS's Nintendo eShop, called "Picross e", "Picross e2", and "Picross e3" released in 2013, with "Picross e4" released in 2014. Nintendo has also released a Pokémon spinoff on December 7, 2015 in the form of the freemium game of "Pokémon Picross" for Nintendo 3DS. "My Nintendo Picross " was released for Nintendo 3DS on March 31, 2016, exclusively as a premium reward for My Nintendo.
