The 24 Hour Puzzle Championship took a break last year and will return next month with its 14th edition. I wrote a set for the 12th edition back in 2011. This puzzle is an obscure type in Nikoli called “Oie e kaerou” [お家へ帰ろう] which translates to something like “returning home”. I named it “Return home” in the actual set.
This was one of the last types to be added in my set that year. I remember having too many number placement puzzles and was struggling to find a different genre that has to be interesting and easy to grasp. I was solving Nikoli’s Puzzle Box and luckily found this type. I made two puzzles: one with “24” and one with “HPC”.

Return Home – Draw arrows from letters to represent a path that it takes. Paths may not intersect each other. In the end each outlined region may contain only one type of letter. All cells must be used by the arrows.
