After solving Mars, the next port of call was Jupiter. Like the Mars cube, this has three Bermuda sides but on this cube, they are all on adjacent faces. The white and blue faces have one Fisher section each, while the red face has two. In the solved position, the only degree of freedom is to rotate the white face. Rotating the white face can free the red face. The red face must then rotated to free up other faces.
The bandaging of the puzzle only allows one of the faces with a square centre to be turned at any one time.
I have not had any popping issues with this puzzle. To turn one of the faces, it has to be aligned accurately in most cases. In situations, where cornering is theoretically possible, it does not turn well. Positioning the faces carefully while performing moves is adviseable.
The scrambled puzzle looks something like this...
Solution
On reaching Jupiter, I realised that there was a pattern to solving the Bermuda cubes. Solve a Petrus-like block that leaves two faces free to turn (even if one of them has been turned out of position). Extend the block to two thirds of the cube and then solve the final layer.Step 1 - Solve the Orange/Green Edge
This is more difficult than it looks but should not present too much of a challenge.Step 2 - Extend Solved Section to the Yellow Face
Solve the yellow/green and yellow/orange edges and the corner between them. The bandaging makes this tricky therefore the moves have to be planned. I do this intuitively.Step 3 - Solve the Blue Pentagon and Triangles
Again the bandaging makes this step challenging. With careful planning, it can be completed intuitively.The puzzle now has a Petrus-like block with freedom of movement on the white and red faces.
Step 4 - Orientate the Remaining Rectangles and Pentagons
These pieces all behave like edges. Orientating the pieces is not difficult.Step 5 - Solve the Red Pentagons
This is a trivial step. The red pentagons behave like edges.At this point, it is advisable to permutate the white pentagon and rectangles, which also behave like edges. This will reveal whether or not there is a parity issue that needs to be resolved. I have yet to work out a neat way of doing this; I just realign the puzzle so that I can turn the orange face by 90° and then fix the damage. Though I do not try to put these pieces in position during the next step.
Step 6 - Orientate the Remaining Squares and Triangles and Solve the Red Triangles
These pieces all behave like corners. This step is very fiddly.Step 7 - Permutate the White Rectangles and Pentagon
These pieces behave like edges. Manoeuvring them into the correct position is not difficult.Step 8 - Permutate the White Squares and Triangles
The bandaging of the puzzle makes this a little fiddly but once I had figured out the algorithms I needed to use it turned out to be not that difficult.One solved Jupiter Bermuda cube.
