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.
#3. Container Cube
Just because this puzzles 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.
The Mastermorphix puzzle is extremely difficult and definitely earns it’s place at #2 on our list. 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. The current largest mass-produced version is the 6×6 Mastermorphix (pictured above) which adds parity to list of why this puzzle is so difficult.
#1. Ghost Cube
Topping out our list is a puzzle that many cubers agree is the most challenging twisty puzzle. 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.
