Shape modifications of some puzzles

Here are five shape modifications of some twisty puzzles. Four of these puzzles were featured on my previous entries.

1. Fisher Cube
The Fisher Cube is a shape modification to the Rubik's Cube. It was made by Tony Fisher around the 1980s. The solution is similar to the solution of the Rubik's Cube but there are extra algorithms to correct the orientation to some pieces. There is a separate algorithm for correcting centers and there is a separate algorithm to correct the orientation of edge pieces.

2. Mastermorphix

This is a shape modification of the Rubik's Cube. Instead of having 6 colors, it has only 4 colors. Looking at the puzzle for the first time would be confusing since the little triangle in the middle of each color seems like the center. Unfortunately, it is a corner piece when you view it as a Rubik's Cube. Solving this puzzle is like solving a Rubik's Cube but you need to try and maintain the orientation of all the center pieces. For me, it is very satisfying each time I solve it since it would take me a few minutes to be able to solve.

3. Gear Ball

This puzzle is a shape variant to the Gear Cube. Solving this puzzle would be similar to the solution of the Gear Cube. This puzzle was introduced in 2012. Like what I said on my previous blog entry, the puzzle reviewers that I saw on YouTube said this is the smoothest puzzle ever.

4. Gear Mastermorpix

Traiphum Prungtaengkit has the aim to modify every mass produced puzzle into the shape of a tetrahedron, preferably a pillowed one. In this case he started with a Gear Cube he purchased from Uwe Meffert himself while both were visiting the Rubiks Cube World Championship 2011 in Bangkok. The modification was made by truncating the puzzle and then filling the holes and gap with black modelling mass.

5. Ghost Cube

The ghost cube is an exercise in making a 3x3x3 shape modification that is as challenging as possible while only allowing one solution. Misaligned layers, odd shaped pieces, and only one color all add to the challenge. There are also higher order cube variants from a 4x4x4 to a 7x7x7 cube. Learning the position of each odd shaped pieces is necessary to solve the cube. While the cube is in its solved state, there are some faces that could not be turned.
