Nintendo announced Pokemon Picross during the recent Nintendo Direct for the 3DS. The game’s Twitter page has revealed Picross’ arrival date for North America and Europe: Thursday, December 3, 2015. What’s more, Pokemon Picross will be free to download, in a similar fashion to Pokemon Shuffle and Pokemon Rumble World.
In Pokemon Picross, players solve number puzzles with the help of Pokemon they’ve acquired in order to complete a portrait of the stage’s featured Pokemon. Doing so will add it to their collection. The download size is currently unknown, but judging from the other free-to-start Pokemon games, it ought to be fairly light.
