With speedcubing gaining popularity day by day, there are now more cubes on the market than ever. I have created this ultimate cube buying guide in order to help you not only to choose the best speed cube but also to discover what makes a good cube and how to choose it.
For those who are totally new to cubes, it is best to read the cube buying guide before looking at the actual cubes below.
Speedcubing is a very complex game and one that requires the player to plan their moves ahead. For this reason, speed cubs are often very expensive. This can make them difficult to buy, especially if you know nothing about the game.
This buying guide will help you avoid the pitfalls that new cubers usually fall into.
How do you choose a good speed cube?
Speed cubes are small, but they’re also small enough to fit in your pocket. And that means they’re always with you, ready for some quick-flicking fun. That’s why it’s important to know what you’re looking for when you’re shopping for a speed cube.
A good speed cube will provide a stable and smooth turning experience. We should consider the following things before buying:
Turning
1. Stability: The cube should be very stable, so it doesn’t wobble around too much when you try to turn it.
2. Stiffness: The cube should not be so soft that the corners will easily pop out of place when you turn them with your fingers.
Corner cutting
The corners should be cut smoothly, with little to no gap between the outer edge of the corner and the centerpiece.
Corners are not too thick: If you have a sizeable gap in your cube, then you will have a hard time turning it when you need to, and the cube will probably become unstable.
Corners are not too thin: If you have a small gap in your cube, then it will be hard for you to turn the corners smoothly when you need to. This can also cause your cube to wobble as well.
Flipping
A good speed cube should be able to flip smoothly. If the corner of your cube is very sharp, then it will probably snap when you try to turn it and cause the cube to become unstable. The edges of a speed cube should also not have sharp.
A good speed cube should be able to do all the basic things that a normal cubers’ cube can do. If it has only limited functions, then you may have trouble when you need to use those functions in certain situations.
Pop resistance
A good speed cube should be able to withstand a minor force before it snaps. If the cube doesn’t have enough pop resistance, then you find it is very easy for your fingers to push out one or more pieces from the cube.
Lock-up resistance
During a rushed or messy move sequence, the cube’s ability to resist locking up. Cutting corners effectively is a “special case” of “lock-up resistance” (A good cube that is lock-up-resistant must also cut corners well).
Control
One of the most important factors that determine Speedcube’s control is its turning speed. Faster cubes have less control and they overshoot while performing algorithms. However, the new trend of magnetizing cubes has contributed a lot to giving cubers more control. There are some speedcubes that you can magnetize yourself, but it is not possible with most of them because of their internal design.
In today’s market, there are a lot of speed cube manufacturers offering magnetized cubes, which provide you a lot more control when performing algorithms. It is good to learn to cube “naturally” when using these 3*3s, although I wouldn’t recommend them to absolute beginners. I would not use a magnetic cube to learn how to cube. But you can and you can learn how to cube with a magnetic cube.
Size and weight of a Speed cube
How many sides does the cube have? (At least 3)
There are different cubes with different numbers of sides, but all cubers agree you need at least 3 sides. The more the better, but if you have a budget, start with a cube that has 2 or 3 sides and upgrade later.
What is the design of the cube? (Inner core)
The inner core of speed cubes is often very important for determining how smooth it will be. The smoothness of the inner core is usually determined by the number of pieces in it, and a cube with an enormous amount of pieces will be less stable than one with fewer.
How big are the pieces? (3mm or 2mm)
The smaller cubes are faster but are less durable. The cubes with 3mm pieces are the most common and are very smooth. However, if you want a cube that is extremely fast or can take some abuse, then 2mm pieces might be better for you.
What is the weight of the cube? (Usually 4 grams)
This is a very important factor. The heavier the cube, the slower it will be. A heavy cube with 3mm pieces can have a smooth turning experience, but will also be quite slow compared to a lighter 2mm cube with fewer sides and no center core.
What are the dimensions of the cube? (Usually 62mm or 54mm)
The smaller cubes are less stable, but they are also faster. The best speed cubes will have a size that fits your hand comfortably and can be rotated quickly with little effort.
Who is the best Speedcuber in the World in 2023?
The best Speedcuber in the world is Yusheng Du the Single fastest 3×3 solving. He has won multiple speedcubing competitions, including his most recent competition in China, Wuhu Open 2018, where he beat a high-level Australian competitor. But Feliks Zemdegs is the champion in Sydney 2019 as the fastest average 3×3 solving.

What is the fastest speed cube method?
The fastest speed cube method is the X-cube. It’s called “the easiest to solve”, but it is also very hard and not for beginners. You need at least 10 minutes to complete a single solution, and even more if you want to get better-than-average results (good for speedcubers). The X-cube method can be divided into two parts: solving the cube in the original orientation, and solving it in a new orientation.
What to look for in a Speed cube?
The principal thing of a speed cube is turning, Corner cutting, stability, control, catching, lockups, tensions, stickers.
-The cube must be very smooth and free of defects.
-A larger diameter than your finger so that you can grip it firmly without worrying about dropping it. The handle should not fit in the palm, but rather around the thumb and middle finger. If the corners are sharp, then you will have to tighten the tension.
-A cube with no grooves is good for beginners, but not if you are an advanced speedcuber who has become accustomed to faster cubes.
-The cube should be relatively smooth and rounded so that it will not come apart during fast solves or be difficulty.
FAQ
Do You Need To Solve Different Types Of Cubes In Order To Get Better At Solving Them?
No, you do not need. Not only you, but many other people struggle with solving a speedcube for the first time. Everyone is a novice. However, there are different techniques that each speedcuber uses to solve the cube faster and with more consistency. One example is “Fridrich” Method.
Which One Should I Buy If I Want To Learn How To Solve A Cube In The Fastest Time Possible?
Speed Cubes are too fast and flexible for beginners. You won’t exactly feel uncomfortable using them. So, you should buy a speed cube if you want to learn to solve a cube in the fastest time.
How Many Times Should I Practice Solving A Cube Each Day, And What Would Be An Ideal Number Of Solves Per Day For Me?
Most people who are the fastest cubers in the world only practice for fun with speed cube. Knowing when to use which algorithm (immediately) can provide the edge you need if you want the cube to be solved in less than 20 seconds. There is still a lot to be learned in improving your techniques, however, it’s not just about how many outputs you do per day. Try improving your technique by 75 to 150 times every day.
