[This is a repost from our archives with new notes at the top (original post here): Making images of smiley faces in puzzle form is one way I try to make the world at least 1% happier. This Wednesday Masyu has a couple less common lookahead steps but should continue to be a good introduction to the genre for those without much prior familiarity (this was a bigger gap in 2013 when the puzzle was written than in 2023).]
