Great puzzle. Must use hard

Milo loves this! Great puzzle. Must use hard, sturdy treats to prevent from breaking when you push them in.

I absolutely love these puzzles, and the added challenge of multiple colors make it that much better. My only complaint is that some of the numbers for the darker colors can be difficult to read.

Fun puzzle and definitely challenging. The pieces could be more sturdy though.

I LOVED this puzzle. My wife and I are avid puzzlers, it took us about 4 months to finish this puzzle working off an on. While this is a difficult puzzle, its not the most difficult. There are plenty of patterns to recognize and words that tell you where the piece goes... it IS a map. The best thing: while you're doing a puzzle, you're learning geography! The only down side- its a huge puzzle, make sure you have the space for it. We had to put the kitchen table together with our study desk and an end table to hold it all.

Deceptively difficult!!! You need to rely almost completely on the shape of the puzzle pieces without clues from the color/design of the picture. Fun and frustrating -- and a sense of accomplishment when completed. Beautiful image, solid pieces, good quality.

This puzzle is great,  the corner cutting in EXCELLENT, It comes pre lubricated, and the cube mechanism is a standard 3x3x3's but it shape shift like a BEAST. I recomend this cube to anyone, This is a not a begineers puzzle though. This is very hard, but easy for an experience cuber such as myself.

We loved doing this puzzle. Love all Lori Schory shaped edged puzzles. Some parts took some time to put together but that's why we love these puzzles. If it's too easy it becomes boring quite fast...too difficult and you just want to give up. Lori's puzzles are just right!

Super fun puzzle and challenging.  Only problem with this one was 2 pieces missing!  Spent forever trying to figure out the area with missing pieces.  I don't know if manufacturer would respond to the issue.  I will try.  Plan on ordering some others because they are so much fun.  I usually do them with a friend to help.

Only issue is that it is pretty much a one time puzzle  It would be very hard to assemble it after it has been disassembled because some pics  show the building shapes & positions.  Also the second layer gets taped to first layer.

I have done many puzzles and this is the second time I do this one. It is very hard to do, compared to others. On one hand, I love it because it is one of my favorite paintings (even though the picture in this box only shows part of it), but on the other hand, the pieces only have two different shapes. In puzzles where the pieces have very different shapes (weird ones, sometimes), you can work fast on the puzzle, but this is not the case. Because there are only two kind of shapes, one piece can fit well in several different spots; this makes the puzzle very hard to finish. If you are a beginner, I do not recommend to start with this puzzle. The puzzle comes with a little bag of powder that, mixed with water (I assume) turns into glue.

I'm giving this a five star rating because this was a really hard puzzle the fun play around with but the only problem is I could get it apart but I couldn't put it back together and then there wasn't any instructions on it so it took me some of forever to put it back together but besides that it's great

Very hard to do. Never  have had trouble doing the 1000 piece puzzles. This is so hard.

Pretty much the most difficult puzzle I have ever done! Got into 3D puzzles, and was doing the little ones that only took a few hours. This one took much longer. But having gotten through it and now having it as a display piece, I can offer tips to make it easier. Sort, sort, sort.
1. Get all "scrap" pieces out. Go through "scrap" pieces again as 1 or 2 was probably missed.
2. Get approx. 10-15 bags and start separating pieces (greenery, crown molding, red brick, yellow brick, cobblestones). I sorted all the grey ones, then went through and sorted them again to more specific types. This will take some time.
3. Once sorted you can start piecing things together! Work one bag at a time. Use the map to figure out what shapes go where. The puzzle "clue map" has the individual shapes of what each "wall" looks like along with how the pieces are shaped exactly. I does not, however, show you what graphics are on each piece. I had to go from looking at the box pictures to the instructions back and forth to figure some things out. Bring a colored pencil with you when doing this so you can color in what you have put together BIG HELP! HIGHLY RECOMMEND DOING THIS.
4 Once you have put every thing together (pieces will all still be flat) LAY ON GROUND AS LAYOUT APPEARS IN ILLUSTRATIONS. Then simply follow directions of how to put together, laying them out on ground makes the directions easier to follow.
5. This puzzle gives you enough direction to get through, but you will need to possess critical thinking skills to "fill in the blanks".
Was a good challenge, some times throughout it I thought it might have been a larger project than I can handle, but 2 weeks later (as I gave up several times for a day or two) it was finished and felt very accomplished. :)

We pasted this to a thick poster board after finishing it, then coated, framed and hung it on the living room wall.  Great conversation piece.  One of the hardest puzzles we've done ... a great challenge.  Just wish some of these guys had been more conservative.

Loved the puzzle. The picture on the puzzle is good and clear. The pieces are a good size and not cheap. I wish they were a little thicker but they are still good non-cheap puzzle pieces. If you love puzzles but don't like the brain numbing 500 piece ones or the kid size ones this was a good medium. I did it with my 16 y/o and 11 y:o. We were able to take sections like the house or the sky and put them together. The most tricky part was the frame which is similar all around the picture.

Once this puzzle is built it is actually quite sturdy. The directions are good but you have to pay close attention to the position of certain pieces. Sometimes it was difficult to read. My daughter gave up at one point but she is only 6 years old and the package does say 8 and up. I completed most of it myself. I did have to go and take some of the pieces apart again and repeat steps because certain pieces were in the wrong place. It does require some patience. Would make a great gift for someone who loves to follow instructions meticulously.

Ravensburger as expected, is one of the best manufacturers of puzzles, this one is no exception. I have done several puzzles of 3000 and 5000 pieces, however, this one is quiet challenging, I consider it the most difficult one I ever tried. I have managed to finish the first half, and now working on the second, it took around 2 months up till now.
I am sure that when it is finished it will be very rewarding, but with a difficult test to my patience.
Nevertheless, I strongly recommend it to puzzle lovers.

If you are looking for a very challenging puzzle, I would recommend this. We simply did not have the patience to complete it for two reasons. First, it seems like they used a small number of dies to cut the pieces as we found many pieces that fit exactly but upon close inspection were not correct. Second the majority of pieces to this puzzle are shades of green. Although my color vision is good enough to pass the tests my eye doctor gives me, had a hard time separating all the shades of green. Prior to this we did a Charley Harper puzzle. Although I wouldn't call it an easy puzzle, it was easy to separate the pieces into groups, assemble the groups and than fit them into the puzzle outline. It was fun to put together with a low frustration level. Would suggest a Charley Harper puzzle unless you really like a challenge!
