While The World Ends With You developer Jupiter has filled the Picross void, Nintendo is about to release a sequel to Picross 3D. That game was for the Nintendo DS while Picross 3D 2 is for Nintendo 3DS.
Picross 3D 2 packs over 300 puzzles with pineapples, seals, and penguins to uncover. The game comes out in Japan on October 1. Picross 3D 2 supports amiibo, but Nintendo has not revealed how.
