Puzzle No. 411-414 : UKPC 2013 Puzzles

Edit: Congratulations to Neil Zussman from UK, the overall winner.

Following up from my non-puzzle post before this, I’m still not well folks. And my laptop’s still not fixed. Overall, not a good time. I’m just hoping everything becomes fine by the time the Championships come along.

Speaking of Championships, the UK Puzzle Championship was held recently, around the same time as the IPC. I contributed 4 puzzles to the UKPC. Two of these were fairly common types, Nurikabe and Corral. I had been doing many Kurotto and Yosenabe puzzles around this time, Yosenabe in particular seemed fresh, so I used that and themed a UK into it, adding to my other UK themed puzzle, the Corral. For the other puzzle, I actually wanted to do either a snake variant or a true-false type puzzle. As is usually the cases with me I just ended up combining both and we have True-False Snake.

Anyway, to the puzzles, (with points as they were awarded to each during the UKPC).

P411: Nurikabe. 15 points.

P412: Yosenabe – Move all circles, vertically or horizontally, so they enter the grey areas. Show the movement of a circle by an arrow, with the tip of the arrow in the first cell it enters of its grey area. Arrows can cross through grey areas if they need to reach a grey area beyond. The arrows do not bend, and do not cross other white circles or lines of other arrows. The number in a grey area must be equal to the sum of the numbers of the circles which enter the area. Empty grey areas may have any sum total, but at least one circle must enter each grey area. Example with solution. 20 points.

P413: Corral. 20 points.

P414: True-False Snake – Draw a snake in the grid of unknown length. The head and tail of the snake are given. The body of the snake cannot touch itself, not even diagonally. The numbers indicate the number of cells the snake visits in the direction of the arrow. If the snake does not pass through a clue cell, then that clue is true, otherwise, it is false. Example with solution. 40 points.

Enjoy!
