Nintendo's own regional pages show that Mario's Super Picross was released outside Japan.

• Nintendo of Europe lists Mario's Super Picross for Wii with a release date of 14-09-2007, and says this Super NES version was originally released only in Japan before being offered on Nintendo platforms in Europe.
• Nintendo of America also lists Mario's Super Picross among the included games in the Super Nintendo Entertainment System – Nintendo Classics / Nintendo Switch Online library.

Because at least one of the Super Famicom Picross titles besides Mario's Picross has been released outside Japan, the statement that only one of those titles was released outside Japan is incorrect.

This appears to be an outdated count.

Official sources now show more than nine Nintendo Switch releases in the Picross S series:

• Jupiter's official product list includes PICROSS S through PICROSS S9, and also later Switch entries with Picross S branding such as PICROSS S+ (Feb. 29, 2024), PICROSS S NAMCO LEGENDARY edition (May 2024), PICROSS S Doraemon & F Characters edition (Mar. 2025), PICROSS S SNK CLASSICS & NEOGEO edition (Nov. 2025), PICROSS S CAPCOM CLASSICS edition (Nov. 2025), and PICROSS S KONAMI ANTIQUES edition (Apr. 2026).
• Nintendo's official store page for PICROSS S+ explicitly calls it "the latest game of the series 'Picross S'", confirming that Nintendo treats at least PICROSS S+ as part of the Picross S series.

So the statement that there are only nine titles in the Picross S series on Switch is incorrect as of 2026.

The date range here is inaccurate.

Official sources show that PICROSS e was released before 2013:

• Nintendo UK's official page for PICROSS e lists its Nintendo 3DS release date as 06/09/2012 in Europe.
• Jupiter's official product list shows PICROSS e released in Jul 2011 (JP) and Jun 2011 (US), with Sep 2012 (EU).

So it is incorrect to say that Picross e, Picross e2, and Picross e3 were all released in 2013. At minimum, Picross e predates 2013 by more than a year in Europe and by two years in Japan and the U.S.
