Thanks.

Yeah, I made it for it, but ended up submitting a different puzzle for the contest.

This is a design idea I stole from a japanese blog. This puzzle is really 8 puzzles. If you were to start in the middle square and expand from there on, every square makes a unique puzzle. So you have a 1x1, 3x3, 5x5, 7x7, 9x9, 11x11, 13x13 and 15x15 fences puzzle. I tried to imply a logical expansion structure with the clue placement, so all puzzles look pretty similar.

As for the difficulty of the puzzles. From 7x7 on the puzzles get harder. I feel on their own, the 11x11 and 13x13 puzzles are a bit easier, but you'll notice certain similar patterns pop up throughout the different puzzles. Not the most common patterns, but they are still there if you know them/recognise them.

Thanks.

Murat made a Masyu with this idea for his Maynipulation test on logic masters india. Had also been inspired by a japanese blog, which had fences puzzles, with other puzzles hidden inside.
It worked out well. I always like messing around with antisymmetry. Will probably try this idea with other puzzles too, but never know how well this is possible.

Like last year, another fences puzzle as a birthday treat from me. The lay out is pretty similar to last year's, except this puzzle has a bit extra. So for you who check the forum, you get to enjoy the full puzzle.
This puzzle is really 2 puzzles in one. It has an antisymmetric counterpart. If you change all 0's to 3's, 1's to 2's, 2's to 1's and 3's to 0's, you get another puzzle.

Enjoy.
