zle, which is the layout of the land and what it was called beforehand. You do get a small colored map beforehand so you have more of an idea how to piece everything together. This may be the most difficult part of the puzzle, since most of the colors are blue, tan, and green. The first layer took me the most time to complete.

The second layer is made out of foam, and if I remember correctly, there should be a picture of what the puzzle should look like when its completed on the opposite side of the first layer map. This part is significantly easier and more interesting, since it's really different from the normal puzzles out there already. It still might take a bit effort to piece everything together, but it shouldn't take as much time compared to the first layer. There is one little flaw though: I personally think that the tape isn't strong enough to fully stick to the first layer. That might be so that it's easier to remove if you happen to place the piece at the wrong place. It's not too big of a deal though, if you have decided where to put the puzzle permanently.

The third and fourth layers are combined together. There's a big, colored printed poster that provides information on the buildings you're about to put up. It tells you the name and the year its established. There's little numbers on the map and on the buildings (if I'm correct, I'll have to check). You put the buildings on the puzzle according to chronological order, and it's really interesting to see how the city "builds up", turning to the New York that it is today. I've learned a lot from the puzzle and realized that there's still a huge chunk of New York that I didn't know about.

I would recommend this to anyone who's interested to learn more about New York, or if they just want to try out an unique puzzle. Either way, it killed a lot of time and I really enjoyed spending time on it. You do need to figure out where you want to put the puzzle at first though, since it was really difficult to move the puzzle once its done and I had to piece some parts of the layers back together.

首先，我不得不说我有点偏见，因为我喜欢玩拼图，而且纽约是我最喜欢的城市。但是我确实相信，非拼图玩家可以试试这款拼图，因为它真的不同于其他普通的拼图。

第一层和普通的拼图一样，是土地和预先准备的事物的布局。你事先得到一个彩色的小地图，所以你有更多的想法关于如何把所有东西放在一起。这可能是拼图中最困难的部分，因为大多数颜色是蓝色，棕褐色和绿色。第一层花了我最多的时间来完成。 

第二层是用泡沫制成的，如果我记得正确的话，那么在第一层地图对面完成的时候，应该会看到拼图具体是什么样的图片。这部分更有趣，因为它已经与普通的拼图真的不同了。将所有内容整理在一起仍然需要一些努力，但与第一层相比，花的时间会少一点。有一点缺陷：我个人认为磁带不够牢固，完全不会粘在第一层。这可能是因为如果碰巧将该片放在错误的地方，那么更容易拿下来。但如果你已经决定把拼图永久放在那里，这就很容易了。 

第三层和第四层结合在一起。有一个大的彩色印刷海报，提供你要建立的建筑物的信息。它告诉你这个名字和它成立的年份。地图上和建筑物上的数字很少（如果我是正确的，我必须检查）。你按照时间顺序把这些建筑物放在拼图上，看到这个城市如何“建立起来”,这是非常有趣的。我从拼图中学到了很多东西，意识到还有一大堆我还不知道的关于纽约的东西。 

我会推荐给有兴趣了解纽约的人，或者只是想尝试独特拼图的人。无论如何，它花费了很多时间，我真的很喜欢花时间在这上面。你确实需要弄清楚你想要把拼图放在哪里，因为一旦完成了这个拼图就很难再移动了，必须把正确的部分拼放在一起。

hile building this awesome puzzle.

Just one thing: The construction and then removal of the Twin Towers is very dark. Not a fan of that. Everything else is amazing!

想给十五岁的儿子找一个喜欢的“玩具”真是太难了（不是电子的），而且还得找那种可以和他妈妈一起花时间玩的玩具。

这个拼图具有教育意义。纽约是一个迷人的城市，在构建这个令人难以置信的拼图的时候，还有很多需要学习和欣赏的地方。

只有一点：双子塔的建造和拆除是非常难的。我不是这个牌子的粉丝，但是一切都很棒！

her!
Only down side... The numbers on the building (to locate their place) had a few mistakes (numbers were swapped) and the numbers were very small on some of them! So have good lighting and reading glasses.
Over all awesome we will be getting another one of these puzzles

base puzzle is good for about 5th grade on up. I am adding that information because some reviews mention that the puzzle was a gift found to be unused later on. The bottom layer is a typical puzzle and though the pieces may seem to be the same, I found that the correct piece always "fit." The second foam layer was easy to put together in minutes rather than hours. It's thickness is needed to hold the buildings in place. Because of the removal of foam "foundations" to place the buildings, the foam part seemed to lose its grip from the double sided sticky tape after a day or so. Also, could have been because of the cooler winter temps. I would suggest that you possibly skip the tape part at first, and if you feel the need you can slip it under pieces later.
The buildings do need a magnifying glass to make the identification of the number easier, but overall the process of identifying and placing of the buildings is quite easy. For me, I would place the buildings up to a certain time period the rest of the family could relate to such as war years, birthdates, etc. Then every day or so the rest of the family would have a sit at the puzzle table and see what the city was like at those landmark dates for our family. Lots of fun for all.

实际上，事先准备了这个拼图，计划玩拼图来打发手术后的漫长时间。对我来说，这是非常值得花钱的东西，这个拼图是一个很好的挑战，帮助打发漫长的日子。作为退休的小学老师，我可以说：

1）一些孩子讨厌拼图；

2）基础拼图对于5年级以上的孩子是有好处的。我补充说，因为一些评论提到，这个拼图本来是当做礼物送人的，但后来发现并没有使用。底层是一个典型的拼图，虽然这些片段似乎是一样的，但我发现正确的片段总是“适合”。第二泡沫层容易在几分钟而不是几小时内放在一起。需要厚度来将建筑物固定在适当位置。由于去除泡沫“基础”来放置建筑物，一天之后，泡沫部分似乎从双面胶带中失去了握力。此外，本来可能是因为寒冷的冬季气氛。我建议您可以先跳过磁带部分，如果您觉得需要，可以稍后将其放下来。

建筑物确实需要一个放大镜，以便识别数字，但总体来说，识别和放置建筑物的过程非常容易。对于我来说，我会将建筑物放置一段时间，家庭的其他人可以与战争年龄，出生日期等相关联。然后每天大家都会在拼图板上，看看这个城市在我们家庭的那些具有里程碑意义的日子，大家都玩的非常开心。

Because the bottom of puzzle is not corrected. I had taken it apart done it over until complex corrected. No pattern, or direction on how to. Just as you see on picture of box is your pattern!

complaint is that you can't move the puzzle without glueing it. The pieces come apart too easily. Also, I wish an information sheet with history was included so you could learn how changes occurred. For example Manhattan had land added to the original Island. Thanks to Google for getting those facts.

非常有趣且信息丰富的拼图。买了旧金山款的，先把它放在木板上再开始拼。孙子也喜欢帮忙。 做工很好，但是有几件丢失了。 他们送了一个替代的拼图给我，很开心，我能够找到一些适合的部分，这点帮助了我！ 我唯一要抱怨的是，你不能在没有粘合的情况下移动这个拼图。 碎片太容易分开了。 此外，我希望包含有历史记录的信息表，以便您了解变更情况。 例如，曼哈顿已将土地添加到原来的岛屿。 感谢能从Google获得这些信息。
