UKPA Open 2017: Arrows

This round was provided for this year's UKPA Open. The round was themed around arrows. I had thought of making a set themed around arrows before. There's a lot of genres that use them, so it could lead to a varied set. I gathered a lot of different genres and tried to select a set that created a significantly varied set. I think I managed to select types that used arrows in different ways. There were a few genres I had tested, that didn't end in the set as they turned out too difficult, or not very enjoyable. A few of the types turned out harder than I thought and I added an easier puzzle to that section.
The set was 75 minutes during the championship. An instruction booklet can be found here.

Puzzles can be found below.

Puzzle #165: Blind Spot

Today the second puzzle that wasn't used in the WPC. This is a Blind Spot puzzle. It's actually a size smaller than the puzzle used at the WPC, which was 7x7. But I actually think this was the harder of the two puzzles. That's why the larger puzzle was used in the WPC. I like writing these puzzles, but I think they can be tricky to solve as the logic is a bit unfamiliar compared to other Latin square type puzzles.

Croatian Puzzle Set

I had been asked to write a puzzle set for a competition in Zagreb last weekend. I wrote a set of puzzles which was a mix of Dutch and Japanese, familiar and unfamiliar, classic and simple variations. There's a lot of puzzle types in here that I havent actually posted on my blog before. The timing of the set was set at 75 minutes, which was longer than the fastest testing. But I have learned from earlier experiences that testing times don't always measure up to the actual test solving. I've added the scores for each puzzle, which equal to 2 points per minute. I think it worked out well, with a mix of easier and harder puzzles. If anyone actually solved them in copetition, I'd love to hear about it.

So here's 14 puzzles in a single post, the most I have done so far. I hope this makes up a bit for the hiatus of a month before. It would of course be easiest to just upload the PDF, but blogspot doesn't seem to offer that option. So instead this post will have all puzzles below.

Puzzle #107: Blind Spot

Here's another genre taken from Naoki's website. Although I think I've seen it before somewhere else as well. It just seem familiar from a few years ago. So possibly it featured on a WPC at one point.
 The first puzzle I made I liked a lot, except I thought it was a bit too hard as the first one on my blog. So I made another one, which was much easier. But I figured I need something a little bit more challenging to post. So I made a third one, which fell a bit in between both puzzles. And instead of posting just one, I'm going to post all 3. If you solve the example and then the first 2 puzzles in order, you should gradually get all the insights to also solve the third puzzle.

This genre was developed by Naoki Inaba

Place an arrow for all four directions (up, down, left right) once in every row and column. No arrow points at another arrow. Black walls block the view of an arrow.
