Masyu 2

I was experimenting with golden ratios and trying to make a board size that is the most aesthetically pleasing.  Since the golden ratio is approximately 1:1.61803399, my choices were somewhere between a board size of 100,000,000 columns by 161,803,399 rows or 2 columns by 3 rows.  I settled for a size that should take fewer seconds to solve than the total number of atoms in the universe.  I thought 10 columns by 16 rows makes a nice looking board, and you should be able to solve it in just a few minutes.





Edit:  I removed a pearl that was unnecessary to arrive at a solution.  I updated the Puz Pre link, too.  I'm sure there's more pearls I could remove, but I'm not that good at getting it to a bare minimum yet.  I just happened to get lucky with the one I took out.

Masyu 1

Here is my first Masyu puzzle.  It moves along pretty quick in the beginning, but I think you'll find a little thinking is required towards the end.





I do realize there are quite a few more givens than you would normally find in this kind of puzzle, but I haven't yet learned how to pare them down to bare minimum.  Give me time.  Hopefully, you'll still find it fun.

Masyu rules

Masyu (also sometimes known as pearls) belongs to the same family as Slitherlink.  They are both puzzles where you must use the clues to draw a single connected loop.  Here are the rules:

1. Use the clues to draw a single, connected loop that does not cross or branch off.
2. Lines must pass through the black circles (or pearls), and must turn at a 90 degree angle within the pearl.  The lines coming out of the pearl on each leg of the angle must continue straight for at least one square.
2. Lines must also pass through the white circles (or pearls), and must go straight through the pearl, but must make a 90 degree turn on at least one of the squares adjacent to the pearl.
3. Not all squares in the grid are required to be filled, but every square with a pearl will have a line through it.

Here's an example:
