Hexagonal Masyu #5-8

I made 4 more recently... The instructions are pretty simple, I think. Not really play tested these puzzles, so there may be flaws.

Hexagonal Masyu #4

This is one where I was trying for the "artistic" side of making a puzzle... I marked 19 cells in the middle in some kind of a symmetric pattern for putting in circles. Surprisingly, it was kind of tough to even make a correct loop that passes through these cells, but eventually I managed to do it. I had to put 3 circles along the rim of the puzzle in order to make it easier (for me) and unique, hence breaking the symmetric look that I was going for...oops. Anyway, I would have liked to have more black circles in there, but alas, that doesn't work. So...after all that useless rambling, here is the puzzle...

Hexagonal Masyu #3

So far, my favourite instance of the original Masyu puzzle is #20 from Nikoli's Puzzle Box 7. That was a good one. Here's a hexagonal version that pays a bit of homage to that, though my version may be easier... (Note: I didn't spend enough time play-testing the puzzles that I post, so they may have some errors in there, or they may be a lot easier than I intended...)

Hexagonal Masyu #2

My second attempt at making this puzzle. I was aiming for a hard puzzle, and was hoping that the centre portion would take some effort to figure out, but perhaps the cells on the rim of the puzzle give it away...

Hexagonal Masyu #1

Here is my first attempt at making this puzzle. I hope it has a unique solution, and should be pretty simple...

Hexagonal Masyu Instruction

Masyu (and I still don't know how to properly pronounce that) is one of my favourite Nikoli puzzles. I find it to be quite easy to do, though sometimes too easy... I've created an extension of this puzzle, tiling the plane with hexagons instead of squares.

Instruction: Find a simple closed loop that travels between adjacent hexagons (cells) via the centres of the hexagons. At each cell containing a white circle, the loop must go straight through the cell, and then make a turn in the very next cell on at least one side of the white cell. At each cell containing a black circle, the loop must make a turn at the cell, and then continue straight for 2 more cells in both directions. The loop can only make 120/240-degree turns, i.e. no sharp 60-degree turns.

Here is an example:
