For those that easily solved the 3x3 cube, Rubix released the Rubix Revenge. Since it is an even amount of cubes per side, it is solved differently than the 3x3. (I have not solved this one.)

Just when you thought that cubes could not get bigger, the 5x5 cubes gets released. Where does it end... (I have not solved this one.)

The V-Cube raises the bar with a new internal design. This cube moves very smoothly. This 6x6 will probably be the maximum size that keeps the square design. (I have not solved this one.)

This V-Cube is unreal. It has a rounded design to make handling easier. They claim to be able to make even larger designs. VISIT THEIR SITE to see more and order one. (I have not solved this one.)

Some where in there, they were nice to those who could not solve any of the above cubes by releasing the 2x2 cube. The Darth Maul brought two classic pieces of history together.

I consider the above cubes "classic" but these type of puzzles did not end with squared cubes. Someone came up with the brilliant idea of joining two cubes. This creates a challenge as the joining piece restricts movement of the 2 cubes. (I have not solved this one.)

How many ways can a cube be cut up and work as a puzzle? Well, I think they are still trying to figure that one out. The Square-1 is unique where the center layer moves only one way.

The Skweb is another example of of cutting up the pieces differently.

The Skweb design was extended to cover a diamond shape....

and pentagon shape. (I have not solved this one.)

Keeping more inline with the original cube design, the pentagon shape was used again in the Megaminx.

Moving away from cubes, some ball shapes have appeared. The Masterball has great significance to me as it was a gift from a great German friend. I have not seen this ball shape before or since.

The pyramid shape came out in the 80's with the 3x3 cube and is one of the easier puzzles to solve. It was not as popular though as the 3x3 cube.

The Platypus has a very different feel than the other puzzles. It has 4 triangular faces that spin and 4 ends that spin. The center piece of each triangle has a color marking on the edge that should match the adjacent face. The movement of the ends is not smooth but do not let this deter you. This puzzle is well made and fun to figure out.

My all time favorite is Alexander's Star. This puzzle looks very complicated but is much easier than it looks (so I think.) The "layers" are seen when looking straight down at the puzzle. You can see this in the white pieces in the picture. A must for all collections!

Tying the favorite spot ,or perhaps a close second, comes the Dogic. This is a BEAUTIFUL puzzle and I love the construction. I purchased the Do-It-Yourself model and was intimated by how many pieces were in the package. It is actually much easier to assemble than it looks. Regardless, I had a ball putting it together! The colored pieces are molded in color; no stickers or glued pieces to deal with. The puzzle if very sturdy and it is relatively easy to spin the faces. A must for all collections!
