nr. 966 - Coralfinder

I didn't created new puzzles for the blog nowadays. I made this Coralfinder some years ago for the 24 hours puzzle championship. Finally I didn't use it. On the last WPC there were a Black and White round in which the Coralfinder had really high points. So I was almost sure that it would be 12x12. I shared this puzzle with the Hungarian team as practise puzzle. I tried to solve this puzzle again during the bus trip between the WSC and WPC. Somehow, I suffered  but Bram de Laat help me to solve my puzzle :) Now I solved it again, and now it was a bit easier than last time :)

nr. 967 - Black and White loop

I have some affinity for forgotten puzzle types. A good exception is the Black and White loop. I have seen this puzzle genre only once, but it seemed a good type for Puzzle Marathon. I'm happy that it was relatively popular. This is my first puzzle since the Marathon.

Rules for Black and White loop

Rules: Black and White Loop

Draw a closed loop through all cells by connecting the centers horizontally and vertically. The loop can't cross or touch itself. Between two circles with same colour the loop cannot turn. Between 2 circles with different colours, the loop must turn exactly once. 

nr. 968 - Yajilin

One more loop puzzle on my favourite layout. This puzzle is very similar to a puzzle of WPC2011 which was created by Pál Madarassy.

Rules for Yajilin

Rules: Yajilin

Colour some cells so that you can draw a closed loop through all remaining white cells. The numbers in the grid tell you how many coloured cells can be seen in the direction of the arrow. No coloured cells are allowed to share an edge. No black bordered square can be used by the loop.

nr 969 - Maxi loop

This is my second puzzle from this genre. I made the first one for the birthday of a friend of mine. Then I wonder how to create a puzzle with only one clue. I hope you will enjoy this simple puzzle. It was fun to create, and a bit interesting to solve.

Rules for Maxi Loop

Rules: Maxi loop

Draw a closed loop through all cells by connecting the centers horizontally and vertically. The loop can't cross or touch itself. The numbers in the boldly marked area indicate the highest amount of cells that the loop goes through consecutively in that area.

nr. 970 - Bosnian Road

This is a standard Bosnian Road puzzle. I like really much this layout.

Rules for Bosnian Road

Rules: Bosnian Road

Draw a loop in the grid by travelling horizontally and vertically without touching itself. The numbers in the grid indicate the number of cells occupied by the loop in the 8 neighbouring cells.

nr. 971 - Masyu

This is an easy, but antisymmetrical Masyu. This week I will focus on loop puzzles.

Rules for Masyu

Rules: Masyu

Draw a single, non-intersecting loop that passes through all circled cells. The loop must go straight through the cells with white circles, with a turn in at least one of the cells immediately before/after each white circle. The loop must make a turn in all the black circles, but must go straight in both cells immediately before/after each black circle. 

nr. 972 - Half dominoes

Finally the 3rd puzzle from this genre.

Rules for Half dominoes

nr. 973 - Tents

Again a Tents puzzle. After the zero and minima clues here is a puzle with all clues. The difficulty of the puzzle is similar to the previous. As you see the grid is almost symmetric which implicates that the solution will be almost symmetric, as well.I don't like that, but I think that the solvers can't utilize the symmetry of  the grid.

nr. 974 - Half dominoes

This is the next Domino puzzle. In general the 7s and bigger numbers provide the starting points. I tried to place as many as I can. I like that this puzzle isn't so easy instead of the big numbers.

Rules for Half dominoes

nr. 975 - Tents

Before the next Dominoes here is another Tents puzzle. Normally a Tents puzzle without any clues is really easy. Especially when we use the uniqueness.
So now I added just the relevant clues. The puzzle solvable logically.

nr. 976 - Half dominoes

I don't know the origin of this puzzle type. But it appeared on all three Hungarian championship. Although in 2011 it was in a twisted form.
I like this type because it can be easy and really hard  in same size. Even all clues are given.
I will publish 3 half dominoes this week. Here is the first with almost all clues. 


Rules for Half dominoes

Rules: Half dominoes

Put all the nine half dominoes into the puzzle grid so that the sum of the dots in certain rows, columns, or diagonals be identical with the given numbers assigned to that certain row, column or diagonal. The pieces may not be rotated or mirrored.

 

nr. 977 - Tents

I like the variations of Tents, too. This is a simple and easy Tents puzzle without any number.

Rules for Tents

Rules: Tents

Place a tent next to every tree, either horizontally or vertically. Tents do not touch each other, not even diagonally and the numbers next to and below the diagram tell how many tents there are in that particular row or column.
