Polish Puzzle Championships 2014: Team Round

This post will contain the puzzles I provided for the Team Round of the Polish Puzzle Championships. It wasn't an official round but a fun thing to do during the evening. Zoltan Horvath had contacted me if I had time to help working on a team round. as I had just finished my individual round, I figured I could. Zoltan came up with the idea of a Puzzle Labyrinth, where you needed to find your way through the labyrinth by solving puzzles and getting a clue to which would be a next puzzle. Eventually this evolved into a labyrinth where the puzzles were missing from the labyrinth and you had to place them back in the labyrinth. We decided to split the puzzles up into four categories, which would be marked in the empty labyrinth.
On Zoltan's suggestion we gave eachother 8 puzzle types, 2 per category, to write and we could choose one puzzle type ourselves. I gave Zoltan Tapa, Yajilin, Thermometers, Haido, LITS, Regional Akari, Yin Yang and Crossing Loop to write. He chose Lighthouses, First Seen Corral, Loop Extra and L-Dissection to write. He gave me Cave/Corral, Number Sea, Grades, Catloop, Retrograde Battleships, Star Battle, Masyu and Penta Blokus to write. I chose to write Kurotto, Laser, Tetromino Areas and Finnish Snake. Most puzzles had no restrictions, except that they shouldn't be too hard. Only the Circles puzzles had the restriction of being monocoloured. This was only a problem for Yin Yang and Masyu as those normally have multiple coloured circles. The Masyu worked pretty well, but Zoltan's Yin Yang topped that way more in difficulty to create. I was impressed with his puzzle. It was fun to solve. He wrote another harder one too.
When the puzzles were done we had to create a labyrinth. I first wrote one where each puzzle gives you one clue. But that labyrinth turned out too hard, so Zoltan rewrote the labyrinth with two clues per puzzle. This way it was easier to solve.
During competition most teams managed to solve the whole labyrinth, with the quickest doing it within 30 minutes.
You can find the Team Round in the following link.

Besides the Team Round, I will be also adding my harder labyrinth for those who like the challenge. You will have 3 options.
You can choose to solve this first file. [Edit: File updated 19-04-12014 5:25am blog time] It contains all puzzles with correct and incorrect clues. You'll need to solve the puzzles to figure out the correct clues and then use those correct clues to place all the puzzles in the grid.
You can choose to solve this second file. It contains all the correct clues only and no puzzles. It also contains a logical opening on page 3 and the solution on page 4. You can also use this after you get stuck on the first file or to check I didn't make a mistake when setting up the first file.
Lastly you can choose to ignore this challenge and just solve the puzzles or maybe solve the original Team Round with the easier clues.
It's up to you.

Puzzle #167: Araf, Nurikabe, Capsules, Catloop

Last weekend were the Polish Sudoku and Puzzle Championships. I wrote a set of puzzles for the championships and helped create a team round with Zoltan Horvath. Today I will be posting the puzzles that didn't make it to the championships. Most of them were too hard for their intended purposes. I will also be posting the puzzles that appeared on the championships later this week.
Three of the puzzle types were from the individual rounds and one is from the team rounds.

The Araf puzzles were the first ones I had written of this type. I still had to get used to construction a bit. When I do that I tend to make the puzzles a bit harder, just to see what's possible. The smaller one isn't too hard, but still a bit harder than intended.
The Nurikabe puzzle isn't actually very hard, but I changed it as I saw an aesthetically nicer version of this puzzle. That one was also a bit easier than this puzzle, which I didn't mind.
The Capsules puzzle was really too hard. It was the first puzzle I'd written for the championships and I hadn't totally finalised my intentions then and thus went a bit overboard on difficulty.
The Catloop puzzle was written for the team round. It is a silly name play on the Catwalk puzzles, which was again a renaming of the Meander puzzle type to give a fun visual theming on the website. I think this type is also known under many other names. The first puzzle is an easy puzzle, while the second is a hard puzzle. I had written the second one first and after feed back written two easier puzzles. One of them went to the team round and the other one was left over. I think this was actually the easier of the two puzzles.

Puzzles can be found below.

Rules: Catloop

Draw a single closed loop through the grid by connecting the centres of cells horizontally and vertically. Numbers on the outside indicate how many cells are used by the loop in that row or column.

This puzzle is a variant on Catwalk. In this puzzle type you draw a path from the given beginning and end point instead of a loop.
