# Top 5 Most Difficult Rubik’s Cubes (Updated)

For the average person, the Rubik’s Cube is quite the challenge. In fact, most people will go their whole lives without solving the world’s most popular puzzle.

However, for puzzle enthusiasts, the standard Rubik’s Cube just isn’t enough. That’s where these next 5 puzzles come in. Chances are you’ll find a few of these in the collections of the most challenge-hungry puzzlers out there.

But before we get to the list of puzzles, we need to answer a question. What makes a puzzle difficult? There seems to be a misconception that the bigger/more pieces a puzzle has, the harder the puzzle is to solve. This is not the case!

For example, solving the 17×17 is essentially the same process as solving a standard 5×5 puzzles. Having more pieces definitely makes it more time-consuming, but it does not make the puzzle more difficult.

What DOES make a twisty puzzle more difficult are things like shape shifting, jumbling (moves becoming blocked), and parity (when the puzzle is in a seemingly unsolvable state due to hidden pieces or similar-looking pieces being misplaced). With that in mind, let’s jump into our list of the top 5 most challenge Rubik’s Cubes!

## #5. Constrained Cube Ultimate

Starting off our list is a puzzle that looks like a typical Rubik’s Cube but don’t let the looks fool you. The Constrained Cube Ultimate only allows for partial moves to be made on all faces but 1. Thus, you are constrained by the number of degrees you can rotate a side. The white side doesn’t even let you turn it at all!

This constraining makes it so many of the algorithms used to solve the standard Rubik’s Cube can no longer be applied. It causes the solver to come up with different algorithms in order to complete certain steps and this is why it ranks as #5 on our list.

## #4. Pitcher Insanity Cube

This puzzle looks awesome, but man oh man is it challenging. Every move is a shape-shifting and jumbling move so it can be difficult to figure out what you’re looking at once it’s scrambled. Some pieces are even hard to fully scramble due to jumbling. Once you get a good scramble, you’ll have to return it back to a cubic shape and then move pieces around individually to solve each face’s color.

## Honorable Mention: Container Cube

We thought this puzzle deserved at least a shoutout. Just because the Container Cube doesn’t have a bunch of pieces doesn’t mean it’s easy to solve! This puzzle is a skewb mod and it looks way easier to solve than it actually is. Adding to the difficulty is having to figure out the color scheme and orientation of the triangular edge pieces since they can appear solved in any orientation.

## #3. Mastermorphix

The standard Mastermorphix puzzle is extremely difficult and definitely earns it’s place at #3 on our list of most difficult twisty puzzles. It’s a shape modification of a standard 3×3 Rubik’s Cube but is much more challenging. The centers need to be orientated correctly and edge pieces can be easily placed in the wrong spot and still look solved. The difficulty increases quite a bit with the higher ordered Mastermorphix puzzles. One of the largest mass-produced version is the 6×6 Mastermorphix (pictured above) which adds parity to list of why this puzzle is so difficult. And of course it also looks unrecognizable once it’s all scrambled up.

## #2. Ghost Cube

Coming in at #2 on our list is a puzzle that many cubers agree is extremely challenging. Despite its level of difficulty, the Ghost Cube is just a 3×3 shape modification. What makes it so difficult is the similarity of pieces and the fact that the layers are offset. This means that you have to partially turn the bottom and top layers before you can even begin scrambling the puzzle. Higher ordered Ghost Cubes are even more difficult and only the most serious of puzzlers usually even attempt to solve them.

## #1. The Impossible Cube

And finally, we have come to the most difficult Rubik’s Cube on our list. It just so happens to be an actual Rubik’s Cube! However, this version is quite a bit harder than the standard Rubik’s Cube. It has tiles that change color depending on the angle you are viewing it from. So a center piece might be yellow but if you rotate the cube at all it’ll change to a completely different color! This is obviously very disorienting. Since each piece/tile has 2 different colors, there are 2 different solved states of the puzzle. From one angle, it’ll look completely scrambled, but from another angle it’ll be solved. It makes our heads hurt just thinking about it and it definitely deserves the #1 spot our list of top 5 most difficult Rubik’s Cubes. Have you attempted to solve any of the puzzles on our list?

PLS CONSIDER EITAN’S STAR

2. Charlie C. says:

I just worked my way through a successful solve of a Rubik’s Impossible Cube. That one definitely belongs on this list. I’ve got the Ghost Cube down but the Impossible Cube was definitely a challenge.

3. Charli says:

These are so cool 😎

4. John says:

Constrained Cube Ultimate is very ez

5. Guest435 says:

Teaching myself the ghost cube took about 3 days (3 days, not a solid 74 hours), and I also solved the Rubik’s “impossible.” That took about a week, but now it only takes a few minutes in good lighting.

6. lol I can solve them all

1. Nevergonnagiveyouup says:

Did you know that in your comment, you didn’t have to say that, because no one asked?

1. dont be mean he just said he can solve all i know no one asked but he said he can solve all rubiks cube

7. Mostly thinking the impossible one is easy, but after trying I will just say: definitely not. It took me almost a week to figure out how does it even work, so it completely, without any thinking, takes the first place on the list.

1. Bruh my first solve took 30 min lol ez
(Literally the first solve)

8. Lol the easiest is the impossible cube
and all the rubix cube is the easiest
and i can solve them in 10 minutes.

9. Did you forget the sudoku cube or is it so easy that you didn’t add it in the list bc me and my brother were arguing about if the ghost cube was harder than the sudoku cube and I wanted to prove him wrong

10. dj says:

i need help on the impossible cube

1. Literally just recognise the colour scheme of each state and the angle u need to look on it from n to have each state

11. alex says:

I am trying the mastermorphix, the normal one

12. So ez all of them took 1.75436 seconds qits freer than a Costco sample

13. Bruh says:

😎

14. Trying ghost cube, got today and was last in stock in my area

15. bru 21×21 think man and 33×33 and rubiks impossible is not imposible

16. Cole Simard says:

Woaw

17. AlwaysGonnaGiveYouUp says:

hello people

does the impossibe cube have t be solved on all angles to be considered solved or just one which the cuber can choose

18. IM THE WALTER MAN... says:

why not the pupet cube v2? took me a solid 2 hours to figure out but i can solve all of thos ther ezzz
