Nintendo is preparing another eShop exclusive, free-to-start Nintendo 3DS game. Pokemon Picross will allow people to solve nonogram puzzles to reveal pictures of Pokemon. It will include characters from every generation.

Pokemon Picross also allows people to purchase Picrittes. Picrittes allow people to get hints when solving puzzles. In addition, “captured” Pokemon will play a role in helping you complete additional puzzles.

You’ll find Pokemon Picross in the Nintendo 3DS eShop in December 2015.
