What was Pokémon Picross?

Pokémon Picross was a Game Boy Color puzzle game developed by Jupiter, the studio behind the Mario's Picross games and Pokémon Pinball, announced in Japanese magazines in the spring of 1999. Previews described a picross game, number puzzles that reveal a picture, built from Pokémon art.

Then it vanished. No release date ever landed, no cancellation was announced, and the game joined the small set of Pokémon titles known mainly from magazine coverage: advertised, screenshotted, and gone.

The story gained a postscript in 2020, when a prototype build surfaced online, complete and playable from start to finish: 217 puzzles, at least one for every one of the 151 Pokémon, with Game Boy Printer support and a Super Game Boy border. It is evidence of how close the game came to the shelf, finished enough to judge, and judged, somewhere inside Nintendo, not to ship.

The concept was sound, which makes the disappearance stranger. Picross was a proven Game Boy genre, Jupiter was its master, and Pokémon in 1999 could sell almost anything. Whatever stopped it, a failed sign-off, a quality judgment, a schedule casualty, was never documented publicly.

The name eventually reached a real game: Pokémon Picross for the Nintendo 3DS in 2015 is a different, free-to-start title that reuses the name, not the lost Game Boy Color game. The original remains the first generation's ghost, documented in this Library so the announcement at least has a shelf.
