Cheap broken box and no bag, allow pieces to fall out and are now missing….
Color: Fifa Mascot 2, Size: 26PCS, Color: Fifa Mascot 2, Size: 26PCS
Tiny little puzzle with no picture and missing pieces….
What you should receive is a very small box, a little larger than a lighter or the size of a key fob. The box is very light weight and flimsy. Mine arrived crushed on the bottom corner and ripped. This is similar to a candy box. Same type and weight. The pieces are not in a bag at all so when my box arrived in the condition it was in, and nothing sealed, of course pieces are missing. There are supposed to be to be 26 and I don’t have but half. They all fell out of the box like candy falls out of a broken box.
The puzzle itself is done by laser and the pieces I do have fit together well but, the color is off. I believe they use a stain and the ink has spread into the other pieces next to them. The color is deep and intense and most is accurately done but some pieces have multiple colors that are not in the right place. Some pieces I can’t tell which side is the front and which side is the back. The pieces are also so small, with so much information crammed on, I can’t make it out as I work on it or once it’s completed the best I can with only part of the pieces. I am disappointed with the whole thing and can only say the laser cutting was done well. Other than that, I wouldn’t order again, especially for a souvenir.

Durable Wooden Puzzle, but the Visuals are Disappointing
Color: Fifa Mascot 1, Size: 26PCS, Color: Fifa Mascot 1, Size: 26PCS
I picked this up to get ready for the 2026 World Cup hype. While it’s a cool idea for a collectible, the final result is a bit of a letdown visually.
The Material
The best thing about this puzzle is that it’s made of wooden pieces rather than the typical thin cardboard you find in cheap puzzles. This gives it a nice weight and makes it feel much more durable. The pieces fit together well and it feels like it will last a long time.
The Problem: Distracting Black Outlines
The main reason for the 3-star rating is the printing and cut quality. As you can see in my photos, the black outlines around every single piece are way too noticeable.
Instead of the pieces blending together to create a smooth, clean image of the World Cup graphics, the whole thing looks "choppy" and fragmented.
Up close, the black seams really take away from the design, making the overall picture look less premium than it does in the stock photos.
Final Verdict
If you just want a quick, sturdy wooden activity for a soccer fan, this is fine. But if you’re looking for a high-quality display piece to show off your 2026 excitement, the heavy black lines might bother you. It’s a decent "mid-tier" collectible, but it could have been much better with a more seamless print.
Pros:
Solid wooden construction (much better than cardboard).
Officially branded 2026 World Cup item.
Easy to handle pieces.
Cons:
Heavy black outlines break up the image.
Doesn't look very "clean" once fully assembled.

The Ultimate Puzzle for Soccer Fans – Beautiful, Challenging & Totally Frame-Worthy ⚽🧩
Color: Wa 26 Ball-200, Size: 200Pcs
As someone who absolutely loves puzzles and is a huge World Cup fan, this one felt like it was made just for me. It combines two of my favorite things—a fun, satisfying puzzle experience and meaningful, display-worthy art—and honestly, it exceeded my expectations.
The design is stunning. The “We Are 26” FIFA World Cup theme gives it that special, collectible feel, especially knowing the 2026 tournament will be hosted across the U.S., Canada, and Mexico. It feels like a piece of history in the making, and that makes completing it even more exciting.
The 200-piece count is perfect for a relaxing but engaging session. It’s not overwhelming, but still gives you that satisfying challenge. I loved how immersive it felt—great for unwinding without staring at a screen, and it really keeps your mind focused and engaged.
What truly sets this puzzle apart is the quality of the wooden pieces. They’re thick (5mm!) and durable, with a really nice weight to them. They fit together beautifully and feel sturdy enough that once completed, the puzzle holds its shape—which is ideal if you plan to display it.
And yes… this is absolutely frame-worthy. The finished 11.8 x 11.8 inch size is perfect for wall décor, and the design looks so clean and polished once complete. I love turning my puzzles into art, and this one looks amazing in a home office or living space—especially for anyone who loves soccer.
Why I love it:
* Official FIFA World Cup 2026 design with real collectible value
* Perfect balance of challenge and relaxation
* Thick, high-quality wooden pieces that feel durable and premium
* Beautiful finished look—ideal for framing or gifting
* Great for puzzle lovers and soccer fans alike
Perfect for gifting: I’ve already decided this will be one of my go-to gifts for friends and family who love soccer. It’s thoughtful, unique, and something they can enjoy and keep.
Final thoughts: If you love puzzles that you can complete, admire, and proudly display, this one is a standout. And if you’re also a World Cup fan? It’s truly the best of both worlds. ⚽✨

Premium Quality, Beautiful Puzzle
Color: Usa Ball-200, Size: 200Pcs, Color: Usa Ball-200, Size: 200Pcs
I will preface this by saying that I am not usually a big fan of puzzles. Puzzles I’ve done in the past are too flimsy and there’s been too much guesswork about whether pieces actually go together. But As a huge fan of the World Cup, this puzzle was a must-have. It far exceeded my expectations! The craftsmanship is outstanding. Each of the pieces is made from thick, high-quality wood (the 5mm thickness really makes a difference), giving it a premium feel that you don’t get with standard cardboard puzzles. There’s a satisfying feel when 2 pieces go together. It actually felt like an accomplishment to finish the whole thing. The fact that it comes with a backing that allows you to permanently fix it in place and display it is another added touch that I loved. It’s just under 12 inches in diameter once complete, which looks great on the wall if you decide to hang yours once finished. I think it’s a great value when compared to standard cardboard puzzles. You can tell that there is actually a lot of thought placed into creating this puzzle.
What really sets this puzzle apart are the unique piece shapes. There are about 10 pieces that are made in themed shapes, like the Statue of Liberty, soccer players, a cleat, etc. Somehow, despite these pieces being there, the puzzle was still a challenge which took me about 2 1/2 hours to finish.
This would make an amazing gift for any soccer fan or puzzle enthusiast, especially with the excitement building around the 2026 tournament.

Officially Licensed, Officially Priced!
Color: Trophy 3, Size: 200Pcs, Color: Trophy 3, Size: 200Pcs
Let me first state that this is a nice package. It's officially licensed, includes everything you need to convert it to make it a permanent decoration (or at least an every four years decoration), and is of very high quality.
The pieces are really cool, I love the variety and the recognizable items. I really only have two complaints:
1. The price. It says FIFA, so you pay for it. This is a high price for a wooden puzzle of this size, as they are usually at least $10 less, plus it's always a bummer giving FIFA any more money.
2. There is a VERY strong chemical aroma, which will hopefully dissipate. The puzzle is shipped in plastic, so hopefully a little more time out of the plastic will improve that aspect.
Overall it's a fun puzzle. I found the black around the trophy to be a bit challenging, but the crazy shapes of the pieces make it easier than it would be with standard puzzle pieces. Plus the unique recognizable pieces help!
I'll give it a solid 4/5 despite my disdain for FIFA and the premium price - that is after-all justifiable to some degree given that we're a couple of months away from the World Cup. The one star deduction is purely down to the chemical aroma.
