3 Otters 3D Maze Ball Puzzle, 6.9-7.5 Inch Brain Teaser Puzzle Sphere | Brain Teaser with Scientific Layouts, Various Tracks, and Multiple Exits. Develops Logic and Focus, Educational Gifts

Great christmas gift for my little brother when he was five. It is pretty large and is made of a strong plastic. Colourful and bright to keep his attention at the time as well. The pieces encased in the plastic never came out of place if thrown either.

My son absolutely loves maze balls. He is 3 years old. He has a smaller version I got from Target that he has played non-stop. We got this one as a new challenge. I was surprised by the size of it, but mostly because I wasn't paying attention to that when I purchased, and due to the comparison of the smaller version we have. Seems decently made. the plastic is a little flimsy, and it is definitely more challenging.

My son loves his mazes and this cubes has been a lot of fun for him.

I got this for my 3 yr old because we have an "adult" one for us. This is much more manageable for him, and even his dad and I enjoyed doing it, even though we both were able to get through it within a couple of hours. It does feel cheaply made compared to the other one we have, so I'm not sure how long it will last. As of now though, it's a big hit. Update: after 1 week my 3 yr old can solve the cube. It's still a challenge, but I got the ball for him now too. This is GREAT for young kids who like their minds being challenged.

Honestly my kids just love these things to bits and this one was for my sons birthday. Total hit btw. Don't drop it though lol. It's fine for what it is, but definitely not designed for to much wear and tear.

My 3 kids (ages 7,7, & 10) and their dad (me) all enjoy puzzle ball/mazes. We already own 4 and I am on the lookout for new versions that we can add to our collection. This ball looked attractive with 138 'new' steps and a bargain price under $20. Too bad it turned out to be a huge disappointment. First, While this puzzle ball boasts 138 'New' steps, much of the design is copied from the original Perplexus ball. You can see in the first photo how the starting block is identical. If you look past that, you can see that the center of the ball is the same spiral as the perplexus, and in front of that the same long run with a 'corregated' style slot. There are many other components that are copied identically. There are some original passages, but if you already own the original puzzle ball, then I estimate that 2/3 of this is a copy of that. Worse, the bargain price isn't just because they've copied so much, but they've also skimped on materials. In the second picture you can see how flimsy the outer plastic ball is. With light pressure, the shell bends under my fingers. I would not trust this ball to survive the drops and handling that my kids inflict on our other puzzle balls. And finally, worst of all, the build quality is so poor that I could not even complete the maze on the copy that was sent to me. In the third picture, you see the ball lodged against the edge of a bridge that it is supposed to pass under. The ball cannot pass under and it's not even close. It's impossible to complete this maze. Based on the first two observations, I might give this a two or three star rating and just warn potential buyers. But even at a bargain price, it makes no sense to buy a puzzle that cannot be completed. I would give zero stars if I could.

the clear shell is hard and thin, similar to a take out food container. It popped a hole in it within a week of playing by 2nd and 3rd graders. This must be used by careful people. the cubed mazes have a thicker plastic and is more suitable for rougher handling. The maze was fun until broken.

Pretty durable, the kids love it.
