The 7X7 Rubik’s cube is the largest cube that is accepted at the official WCA competitions. Meaning that there is no official discipline for bigger cubes.
I welcome you to the world of the 7X7 speedcubes. It is so awesome that you are here and that you are ready for the challenge the 7X7 is.
But first things first, you need a cube and I am here to help you get the right one and not something that will get stuck, lock up or worse. You don’t want these.
As you probably already know the bigger the cube the harder it gets to design and manufacture it. Smaller cubes like the 2×2 or 3×3 are so much better than the bigger cubes because they are easier to make.
In this buying guide, I will share with you what are the important characteristics you need to pay attention to and what are the best 7X7 cubes on the market.

The Most Important Features of the 7X7X7 Rubik’s Cube
These characteristics will determine the overall cubing experience on your 7X7 speed cube and if you already don’t know about how these impact the cube’s performance I suggest you read this part of the buying guide. If on another hand you are experienced then just skip down to the actual reviews.
I wrote more about the essential speedcube characteristics in this Rubik’s cube buying guide here where you can also read the reviews for the awesome 3 by 3 puzzles too.
Control and Speed
When it comes to control and speed with the 7X7 rubik’s cube you will want to have a good balance of those. Unless you prefer having as much of speed or control possible its best to have a balance of the two.
Adding lubes and tensioning the speedcube will help you get the balance that works for you.
Just keep in mind that with so many layers it is very easy to overshoot and lose control. Without enough friction between the layers you will risk getting the layers to mess up.
Corner cutting is one of the most important characteristics for speedcubing regardless of the puzzle size. However, it is definitely one of the most important features of the 7X7X7 puzzles because it is important for at least the outer layer to be able to complete the turn even if the vertical face is not properly aligned.
With cubes that have manly layers like 5×5, 6×6 or 7×7 it is not realistic to expect the quality of corner cutting that you will get with the cubes of smaller dimensions. Unfortunately, that’s the way it is.
But thanks to the advancements some 7×7 manufacturers have been making there are now pretty good options on the marketplace.
7X7 Cubes Stability
Stability of the 7X7 needs to pass these checkmarks:
- It shouldn’t feel rigid but instead should be a bit flexible
- It must not have significant deformations when cubing. You don’t want pieces twisting or catching.
- Most importantly your 7X7 speed cube should not pop up
Their complex design will always have these cubes in danger of experiencing pop ups which means that the piece of the puzzle can pop out of its place when you are solving the cube.
But there have been many improvements in the design of these puzzles and thankfully there are now bigger cubes available which are way better than what they used to be. Meaning they will experience significantly fewer pop ups.
Reviews of the best 7X7 cubes:
1. YuXin Hays 7×7 M
Hays is definitely my favorite and all round best 7X7 in my opinion. It has a great combination of speed, control and the stability.
When this puzzle first appeared on the market it absolutely disrupted the entire 7X7 production because it was so much better than any other cube at the time of its release. It is also responsible for huge drops of PB records on the official cubing competitions.
The Hays has a smooth and crunchy feeling which is very nice and satisfying. It is also very fast but in a great combination with the control. The magnets on this puzzle are much stronger in the inner layers than on the outer layers which is good and will help keep the central parts of the puzzle in place while speedsolving.
Another thing I like about the Hays is its mechanism design. This is the 7X7 rubiks cube that has the least tendency to lock ups and pop ups making it the best option for people who want the smooth cubing experience without the least amount of unnecessary frustrations.
This is the medium sized and weighted puzzle among these three. Coming in at 67.5mm in dimension and the weight of 204 grams.
Turning: Fast and smooth turning, Corner cutting: Average, Control: Great, Catching: Not often, Lockups: Very Rare, Popups: Very Rare, Speed Solving: Great
2. X-Man Design Spark 7X7 M
X-Man Spark from QiYi is one of the best 7X7 rubik’s cubes for speedsolving. It is the fastest of the three listed here.
This 7X7X7 is very fast and has a very nice crispy feel to it. But aside from its speed it is also quite smooth and controllable. The magnets are quite strong and they get stronger as the layers progress inwards. This is a good thing because it helps you keep what you solved while working on the outer layers.
The corner cutting on the Spark is pretty good for a 7×7. It can corner cut a little bit more than one layer.
The Spark’s dimension is 66.5mm and it weighs 196.1 grams. This makes it the most compact and the lightest 7X7 on the market. This is actually an important metric. Just practicing your speedsolving on the 7×7 can cause your hands to get fatigued so it is good when the puzzle is lighter.
When it comes to the pop ups and the lock ups I have to say that they do happen but not as often as you would expect from the 7x7s. The overall design of the puzzle is great and if you tension the cube a bit it will help to reduce the pop ups even further.
Turning: Fast turning, Corner cutting: Average, Control: Great, Catching: Not often, Lockups: Rare, Popups: Rare, Speed Solving: Very good
3. Moyu Aofu GTS M 7X7
I love MoYu puzzles but this one will have to take third place in my book. Overall this puzzle is considered a budget option amongst the top 7X7X7 speed cubes in the speedcubing community.
First of all, it is the cheapest of the three but it does have its drawbacks when compared to the Hays and the Spark above.
The AoFu is pretty dry and slow out of the box which does improve after you break it in and lube it but it still remains the slowest on the list. However, this should only concern you if you are an active speedcuber who is after their PB all the time.
Regardless of the fact that it is slower than the two above puzzles this one still beats all the other 7x7s on the market except the Hays and the Spark.
Some cubers may actually like the slower and buttery smooth performance of the MoYu Aofu because it provides great control during the solves. Magnets on it are moderately strong on the inner layers but are actually quite weak on the outer layer which is also a minus.
The AoFu is the heaviest and the biggest of the 7X7 rubik cubes on the list with its weight of 234.1 grams and its size of 68mm. This is something you definitely want to keep in mind. Most people will tire their hands with that weight if they practice on it for longer periods of time.
Corner cutting is good like on the other two above. It can be done but don’t expect anything over the one layer.
The AoFu also has a tendency for pop ups but nothing that’s too bad. If you are not very rough and fast with it these shouldn’t happen very often. One thing I liked particularly about the AoFu is that it doesn’t have many lockups which means more fluid solving and less frustration.
Turning: Smooth sluggish turning, Corner cutting: Average, Control: Great, Catching: Not often, Lockups: Very Rare, Popups: Rare, Speed Solving: Good
Depending on your needs as a cuber you should find what works for you. These are considered overall as the best options on the market and you can’t go wrong with either of them depending on what you need.
