The 7×7 cube is the highest layer puzzle that is an official speed cubing event. Along with the 6×6 cube the 7×7 cube was introduced into the market much later then the earlier speed cube puzzles. The mechanism, which was thought to be impossible to make, is so much more complex with a lot more parts. This results in some really horrible 7×7 cubes, luckily some 7×7 cubes make for a really good 7×7 speed cube.

The Shengshou 7×7 can corner cut just as good as the V-cube 7 and has very smooth turning. Shenghsou 7 really shines with the it’s turning which is very smooth and fast which requires very little effort. The Shengshou 7×7 is not known to pop however has a real problem with lock ups. Some lock up may be small which can be fixed quickly but some lock ups just totally seize the cube ruining a solve.
The Moyu Aofu is the newest 7×7 speed cube that entered the market. It adopted the pillowed shape of the V-Cube which makes it handling the Cube so much compfortable then conventional square shaped cubes. The very smooth turning of the Moyu Aofu is what really stands out. Corner cutting is very good and popping is non existant. The flaws of the Aofu is because of it’s size the corner pieces are really quite small, so solving in the 3×3 stage can be quite tricky. On the rare occurrences that the corner cutting and smoothness isn’t enough it will lock up and it may be quite messy.
The Moyu Aofu GT is the newly improved version of the Aofu and the “GT” moniker implies that it the better performing version of the model. The Moyu Aufo GT came out around a year later from the Moyu Aofu and it’s release was quite anticipated by many. It took the cubic shape over the pillowed version which really addresses the problem of the small corners on the 3×3 stage. The main difference this has over the pillowed version is that it is not as fast as the pillowed version but is more smoother and controllable. Other then that it shares the other characteristics with the pillowed version like it’s good corner cutting, lack of pieces popping and unfortunately the way it gets very stuck when misaligned.
Which 7×7 speed cube to get?
The Shengshou 7×7 is a decent speed cube which is a great if you are strapped for cash although clearly the Moyu Aofu and Aofu GT will battle for first place here. When it comes to the Moyu Aofu and the Moyu Aofu GT it boils down to two things – shape and turning style.
- The pillowed shape obviously is quite popular when it comes to big cubes since there is so much layers involved a pillowed shape really helps hold the cube in your hands and turn each and every layer. However, the pillowed shape really is a disadvantage when it comes to the last 3×3 stage where the corner pieces are way too small. The pillowed shape is more for convenience while the cubic shape is more for speed cubing.
- Turning style is a bit different between these two with the pillowed version being a bit faster and the cubic version to be a lot smoother. With 3×3 speed cubes these two are preferences although with bigger cubes I think that smoother is more important simply because there are so much more layers and you really
wantneed a lot of control which a smoother cube provides.
With these two points the clear winner here is the Moyu Aofu GT with its smoother turning layers and it’s cubic shape which is more suitable for speed cubing.
