About
Pokémon Picross (Japanese: ポケモンピクロス Pokémon Picross), not to be confused with the 3DS game with the same name, was a Game Boy Color game slated for release in 1999, with snapshots of the game published in several video game magazines, but was ultimately scrapped.
A near-final prototype dump of the game was surfaced online on September 10, 2020, as part of a major leak of Game Boy / Game Boy Color prototypes, which was dubbed "Nintendo Gigaleak 3" by the fans.
