Puzzle 32: Lits 3 (Redo)

Well it turns out my first version of Puzzle 32 had more than 1000 different solutions (thanks Prasanna for noticing). I have fixed it, and have verified that this one has only one solution, but I have made the puzzle substantially harder (or harder than I thought it was...). By the way, sorry that I have not been publishing much recently - I have been preparing for the Google Code Jam Qualification Round.

Hope you enjoy.

Puzzle 29: Masyu 5

My first Masyu with perfect anti-symmetry (every white circle is 180 degree symmetric from a black circle and vice versa).

Puzzle 25: Masyu 4

Puzzle 15: Nurikabe 5

I am going to label this one as hard. Let me know if you think otherwise.

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)
