So why dice dot holes over colors? Do they help you feel your way around it?
Good questions!
The dice dot holes were basically for random fun, I wasn't able to properly solve a Rubik's Cube as a kid.
But as I grew older, eventually it crossed my mind that the cube totally lends itself to being a die (singular of dice).
And yes, I can partly feel my way even blindfolded or behind my back to solve it, but due to repetitive/alternating patterns of the center dots, it's impossible to solve any old random pattern completely blindfolded, it has to be arranged in advance.
A surprising lot of those sort of puzzles are self-reversible though, as in the same mixup also becomes the very same puzzle solution.
The only unique dots you can feel come from the #6 side, which is the only side that has two dots in the middle of the side edges. I chose yellow as the #6 side. But due to the various ways the dots can mirror, it can't outright be solved blindly from a random shuffle.
Here's one of my study graphs on it, plus links to photos of my original die/cube contraptions.

Oh! I'm glad you shared that because I was imagining something different. I was imagining each individual square having one to six dots on them. A completed the cube would then have the same set of dots on each face.
What you have there is pretty neat!
I would have guessed 100% are this way, am I missing something about how Rubik’s cubes work?
No no, what you're thinking of is if you do all the same steps in exact reverse backwards order, that's always the solution, and yes that is 100% true.
What I'm saying is within this rather large subset of crossover cube/die puzzles, then performing all the same steps forwards is both the mixup and also the solution. That is not true for all Rubik's puzzles though.
A lot of that has to do with 2x turns, most of the easier cube/die puzzles use nothing but 2x turns. But within the full Rubik's puzzle possibilities, there are an almost infinite number of 1x turns, which when solving means you basically have to do a -1x turn for every 1x turn that mixed it up.
I've also found some extra crossover cube/die puzzles that do incorporate 1x turns, those add a little extra challenge to the solutions, but many of those even have the same solution, if and only if you flip the cube to start from the exact opposite three centers as where the mixup started.
Sigh, sorry if this sounds confusing, but that's kinda just how the cube is, confusing, while still being such a simple mechanism.
