Puzzle 36: Akari 4

Hope you enjoy.

Puzzle 35: Tatami 1

Sorry that I have been away for so long, avid readers. I have been preparing for the summer of programming contests (Google Code Jam, TopCoder Open and the Internet Puzzle Solving Contest).

Hopefully I should be back to my usual one-puzzle-per-weekday schedule. Let me know if there are any types of puzzle you would particularly like to see.

Puzzle 34: Bag 1

As requested, a corral puzzle.

Puzzle 33: Nurikabe 6

Thought I'd make a bit of an easier puzzle today. (Let me know if that didn't work out)

Puzzle 32: LITS 3

Hope you enjoy.

Puzzle 31: Masyu 6

Another anti-symmetric Masyu.

Puzzle 27: Heyawake 4

Fiddlier end of medium, I'd say.

Puzzle 25: Masyu 4

Puzzle 23: Masyu 3

Hope you enjoy! Do you guys think it is beneficial to have difficulty ratings on these puzzles or not?

Puzzle 22: Tentai Show 1

Thanks to my long time collaborator Dave T for the picture.

Puzzle 20: Mochikoro 1

My first attempt at constructing this style of puzzle. Let me know if there are any other styles of puzzle you would like to see.

Small but Perfectly Formed 5: Akari 3

This temporarily draws to a close the short 4x4 puzzle section.

Small but Perfectly Formed 4: Hitori 1

I like the diagonal symmetry of this grid.

Small but Perfectly Formed 1: Nurikabe 4

To celebrate having moved my blog from Twitter, I am starting a series of small but interesting puzzles. Being as the number of possibilities are much smaller on such a small grid, it is possible that they have appeared elsewhere. If so, I hastily apologise.

Puzzle 12: Masyu 2

Another Masyu for you. The rules are at http://en.wikipedia.org/wiki/Masyu.

Puzzle 11: Akari 2

Another Akari for you.

Rules are available here: http://en.wikipedia.org/wiki/Light_Up

Summary of the rules: put light bulbs in some of the squares so that all of the squares are lit, but no two light bulbs light each other. The black squares block light, and each number indicates the number of adjacent squares that contain light bulbs. (The light bulbs are semi-polarized in such a way that they only shine horizontally or vertically)

Puzzle 10: Slants 1

Decided to go with the English name of “Slants” for this rather than the Japanese “Gokigen Naname”.

Puzzle 9: Nurikabe 2

Getting a bit repetitive with all of these Nurikabes, I know, but here you go. This one is a bit harder than the previous one.

Puzzle 8: Suraromu 1

I quite like the way this one works.

Puzzle 6: Sudoku 1

In my interest in bringing you new puzzle types you might not have seen before, I bring you “Sudoku”. It might feel a bit unusual to start off with, but it’s worth giving it a go.
