The curse of the “non-unique-pieces”, yes I agree this puzzle is a stinker, it is much harder than it looks. The piece shapes are much like the “Snowbirds” puzzle, blocky rectangular, many of them are identical and can fit in wrong places. I often average 2 pieces per minute and with this puzzle I needed 200 minutes for 181 pieces. Maybe Kind of hard difficulity?
The puzzle has 3 distinct blue horizons and differentiating between the blue water and the low blue sky is a challenge. The yellow-green foreground is different than yellow blue sky.
First find the arms of the windmill. Then I worked the puzzle like a layer cake, paying close attention to shades of color and I had minimal do-overs.
The brown-yellow lower left corner stands out; next find all the lower right yellow green to finish the bottom. Naturally any pieces that feature the blue water – yellow green foreground are the next layer up. To summarize, one can segregate by colors and combinations of colors and work in layers from bottom to top. I actually worked both from bottom to top; and from top to bottom, finishing the pure yellow last.
Those who are blessed with a keen eye for very subtle nuances of color and shade will have a big advantage with this puzzle. Excellent lighting is a big help.
If I remember correctly compared to snowbirds each piece is much finer scale.
I loved the subtle shades of vibrant colors. The dark green is very dark, I’d offer black with green streaks. There is just enough color information to find the proper place for each piece.
By now you should own a puzzle hemostat so I’ll not mention it again. Even with great care I needed it several times to remove wrong guesses.
BTW, I can find this puzzle on Amazon, it might be a Artifactpuzzle.com exclusive.
