One of the four new games available on the Nintendo Switch Online service next week is Mario's Super Picross, a puzzle game that launched for the Super Famicom back in 1995.

This is actually the first time it's ever appeared in the US; European fans were lucky enough to try it out through the Virtual Console service on Wii U and 3DS, but otherwise, it's only ever been seen in Japan. As such, Nintendo's released a tutorial for the game for anyone struggling to understand what's going on.

If you've played any Picross games before you'll instantly feel at home, but for those who haven't, the video above goes through the basics of chipping away at each stage. It's all about keeping a close eye on the numbers at the top and left-hand-side of your puzzle, as these indicate how many squares can be knocked away in each column or row.

We'd argue that Picross can be a fantastic way to pass the time, especially when it doubles up as a quirky Mario game that only originally launched in Japan. If you haven't already, make sure to check it out when you get the chance.
