When revisiting the GAPP Portal Loop puzzles, I found this mysterious note… 📜 It appears to have been sent here from a parallel universe. There, the Simple Puzzles and Clarifying Examples team (SPACE) publishes a logic puzzle each day. You can earn a Fast Frog 🐸 if you solve within the fastest time limit! Today’s puzzle, posted by a user whose profile picture is a rotated flushed_bread emoji, is a Syuma, the most popular genre from Japanese puzzle company Cairn Rouge. After a retired judge convinced the London Times to print Syuma puzzles made using his generator, the genre took off, and is now printed in newspapers around the world!

Rules: Draw a non-intersecting loop through the centers of some cells that passes through every circle. The loop must turn on black circles and travel straight through at least one of the cells on either side. The loop must go straight through white circles, and turn in both of the cells on either side.

Here’s a GAPP 101: Just like Masyu, this genre has a lot of patterns. White circles are more powerful because they constrain both adjacent cells; in particular, look for white circles along an edge or with a segment pointed towards them.
