Ro puzzle (aka Twiddle) — virtual 2d puzzle

[Roman]

bestsiteever.ru/ro


The puzzle is quite similar to 15 puzzle except for "parities" (situation when you need to swap just 2 pcs) for which I haven't found any optimal way to solve yet.

Ro comes from "Rotation" - 4 tiles rotate around the common point. I will add more "rules", such as "Di" (2 pairs of tiles are switched diagonally) and other surprising ones.

I'm not convinced that Ro stands for rotation and not Roman

Looks cool. You’re, right it is very similar to the fifteen puzzle. It also reminded me of a loopover which many of you have heard about: https://www.openprocessing.org/sketch/576328/

Because this moves in rotations, it could be expressed as a 3D puzzle too, couldn’t it?

Also, it's not working properly in Firefox.

Wow, very nice!

Nice! I got a 16.27 first try cause of a last row skip.

Cool, thanks! I was sure someone has done it long before me, I just didn't know how to find it. The idea of this puzzle is way too obvious so no surprise multiple people came up with it independently of each other.

Keyboard control is cool, although I prefer UIKJ instead of IOKL because that's where your index and middle fingers lay when you are using proper touchtyping techniques. So I added it ty my version. (Gonna fix firefox mouse-control bug later)

I have also made a solver and generated some algs. As an easter egg, pressing shift+H will display algs cheet sheet on the page. These cases are tile cycles, and the algs are displayed are in "watch-and-type" notation. These algs was choosen based on how ergonomic they are form touchtyping perspective.

function windowKd(e) {
    var code = e.keyCode || e.which;
    //…
}

You should use KeyboardEvent.code (rather than keyCode/which) so all those weirdos not using qwerty can still use the same keys. (UIJK are still next to one another on Dvorak, just by coincidence (they're where FGCV are on qwerty), but that's less ergonomic.)

loopover V1.2 has advanced features like blind, fingersize or no regrip:

Loopover v1.2 - Cary Huang - OpenProcessing

v1.1 was 2 weeks old, and bad. Here's a better version.

Cool! It would be interesting if there where rankings, not sure how feasible that is though.

Now that's a twisty puzzle!

 

[Etotheipi]

This was annoying.

Can you add counterclockwise support on mobile? Maybe a shift button on the website they you could use to emulate a shift press?

It is already a thing.
