I will be using my new page from now on (and you should be, too)! This page will remain, but will sooner or later be outdated, and only contain old versions of SkewbSkills.
This is due to the fact that my new page will not only contain the SkewbSkills application, but some more content and better design. So I created a new repository on github, where you will find all data and files required for the website only, while the old repo will serve as a place to store mostly python files for the offline version.
Practice and learn skewb algs, first layer and more!
This description intends to show you how to use SkewbSkills and give a quick overview on the development process.
SkewbSkills is now available as a webpage and can be downloaded as a .zip folder, containing an .exe. Read more about installation below.
SkewbSkills is free to use for all skewbers out there (!) and has been created by Annika Stein (also known as HugaCuba on social media such as YouTube or Instagram) to
- practice the first layer
- practice algs for the last two layers
- practice programming with python and qt
- practice html, css and javascript!
Happy new year to all skewbers!
Finally you can use the major improvements also in SkewbSkills .exe, we've got WCA scrambles, a button to hide or show the scramble image and some minor design updates and bugfixes. Be sure to check out the new version by downloading the corresponding .zip-archive here!
Maybe you already noticed (using github) that I am working on a rebuild of my website, and it is already accessible under this link.
The page you are using now will remain most likely as an archive of old versions, and serve as a redirecting page to the new one.
I recommend switching to the new website, where I will not only host SkewbSkills (Web, offline etc.), but also include other topics related to improving at skewb, algorithms, practicing techniques... there's a lot to come!
You can now use a nice feature of SkewbSkillsWeb (and also SkewbSkills .exe in the future): WCA notation scrambles instead of Rubiksskewb notation for the Last 2 Layer Trainer!
I wrote a python module that transforms Rubiksskewb to WCA notation, given that the initial scramble consists of the moves like the ones in this document (credits: Elias Malomgré and Carter Cucala).
Although I already used it for both SkewbSkillsWeb (.js) and the .py version, its source code is also available here on my Github repository, as usual. You can of course also use it as a standalone notation converter, but right now it lacks a grafical user interface. So it is just for those of you familiar with either .js or .py files and such. But as I said before, you don't have to do this on your own to use SkewbSkills, it's already implemented for all the LL cases that were included already.
Actually, this was the most difficult part on my programming journey so far, not because programming is complicated, but because even solving this problem on paper was sort of impossible for me at the beginning of my thought process.
Now I'm wishing you all nice holidays and I'm looking forward to publishing a new .exe bundle soon for those of you that want to use SkewbSkills offline.
And as always: feel free to comment any bugs, ideas, feature requests, experiences...
... I added some buttons (for each case!) that make you select exactly the cases you want to practice. Also, the possibility to select groups of algs is still there, so using both approaches, you can at least increase the probability to receive certain cases up to a factor of 2.
Another minor improvement is a simple button that lets you show or hide the scramble image as has been requested some time ago in the FB group "Cyoubx's Friends" and / or "Skewbers". Thank you all for your ideas and critique, it helped a lot! Sorry that it took longer than expected, physics is time consuming. ;)
You can now use a stopwatch on SkewbSkillsWeb, on any mobile device or on a laptop / computer / whatever! The responsive design of the jekyll theme allows us to adjust the size and appearance of buttons and content, giving us a nice layout everywhere.
And if you improve your best time for each L2L case, a prompt is going to tell you that you got a PB!
You might not be able to change / adjust the scrambles atm, but the feature mentioned above is SkewbSkiilsWeb-only and kind of a compensation. ;)
Hopefully, someday more statistics will be implemented to get detailed insight in your improvement.
Yes, you've heard correctly, SkewbSkills is now available as a webpage! This very first web-based release might look a little ugly and lack a stopwatch, but it WORKS, apart from that! :)
Believe me or not, getting everything done in JavaScript was a bit of a mess as a complete .js newbie, but using my python scripts saved me a lot of time. Tbh, it took me not more than three days (the last time using anything like html / css must have been several years ago).
Seems like learning new languages is much easier than learning your first one. ;) (yOu DOn'T sAY?!)
- Create subfolders that contain the scrambles and icons (thanks to Elias for the suggestion)
- Added 'General Functions' menu with shortcut to close the window
- Minor changes of the tooltips
Download v1.2 as a .zip-folder here.
- Better way to generate the first layer trainer scrambles, less code, less disk space - faster in general.
- (GERMAN) Video on SkewbSkills is published here!
- Stopwatch for the FLT, higher accuracy of the stopwatch compared to the first version
- "Guide" for non-windows users added down below
- minimum width of the scramble drawing to prevent overlap with the third column
Download v1.1 as a .zip-folder here.
You can now download and use version 1.1 of SkewbSkills! Browse through the source code on github or simply run the executable and have fun! More info on how to install your own copy of SkewbSkills down below.
Download v1.0 as a .zip-folder here.
- Add other practicing modes, or modify the current ones:
- I'd like the user to identify weak algs and put them on a special pile to work on particularly
- add quiz where you only see three faces and have to identify the case
- add competition sim where you get five scrambles, but only four times a day ;)
- add statistics for every L2L case that shows improvement
- function to identify which cases you know, where you can put in your own algs and keep track of the cases you know
- Make SkewbSkills available to more platforms than Windows (see paragraph below for more information)
You don't need to worry about downloading or installing anything, you can access SkewbSkills now directly from the web, as a webbased application!
If you want to, grab yourself a browser that is able to store websites (save all data required, e.g. by pressing Ctrl + S) and use SkewbSkills offline, as well!
Download the zip-file, containing the .exe, some pictures and .txt files. Do not move the .txt-files out of the directory, they contain the scrambles. Actually, using my pictures is not necessary, but they are included for design purposes.
To open the program, extract the zip-folder and open "SkewbSkills.exe" (v1.1 and up) or "MainWindow.exe" (v1.0), either by using the executable itself, by defining a shortcut (which is pretty nice if you want to put the program on your desktop or the taskbar). What you can also do is run the MainWindow.py-code (for those of you that have a python interpreter set up). For the latter, you would have to download the sources in the repository and make sure all packages are installed. Therefore, this option is only recommended for more experienced users, because you might have to get PyQt5 etc. before you can run the application.
Note: since the .exe is really new and not many people use it, you might have to allow your computer to execute it. This also applies to antivirus software if you use some.
At the moment, SkewbSkills is only available as an .exe-file. Therefore, if you want to use SkewbSkills on a different platform than windows, you might want to consider using a software called "Wine" (freeware, on macOS or Linux for example).

- ENGLISH Tutorial for macOS
- GERMAN Tutorial for Linux
- ENGLISH Tutorial for Linux
Besides that, there is always the option to download the sources and run "MainWindow.py" on your machine using Python 3.
If I'm informed correctly, it should already be possible for linux users to run python files, but the package 'PyQt5' has to be installed.
Updating your version of SkewbSkills is pretty easy. Just download the newest .zip-folder and remove the previous one. It's also possible to use more than one version on the same device, if you do not mix the files into one folder or randomly copy/paste from one to another version.
If you have modified your scrambles and want to use them in your updated version of SkewbSkills, download the newest version and only change each scramble file you have overwritten with your own algs. In newer versions, the files might be located in other folders, but they will be named the same way as before.
After opening SkewbSkills, type "H" or choose Help from the menubar to get (almost) the same instructions as below. You can close every window inside SkewbSkills by pressing ESCAPE.
Choose any from the different practicing modes, by pressing the corresponding button or key, respectively. A new window appears, the starting window closes. Note: the First Layer Trainer might take some time to open, so be a little patient (especially for v1.0 users).
There's a slider to define the length of the scrambles, you can choose between 1 and 7 moves. This can also be done with the keys 1 to 7 on your keyboard, if you're using v1.1 and up. If you want the scrambles to be shuffled, use the checkbox "Shuffle scrambles" (shortcut: S). The checkbox "Use all colours" (with its shortcut C) allows SkewbSkills to show you various colours so that you can practice to start the first layer with every color (to become CN). When you're ready with the customization, press "Generate Scramble + Colour" (or RETURN). A new scramble appears, both as a label containing the scramble sequence, and with a drawing. If you want to time yourself solving the first layer, use the stopwatch with its two buttons, Start (SPACE) / Pause (SPACE) and Reset (R). Small warning, especially for v1.0: the more moves you select, the larger the files are that contain the scrambles. Therefore, it might take a little until the process is completed. In further versions such as v1.1 and up, this should not be the case anymore.
Select all the alg sets that you'd like to practice. This can be done manually by checking or unchecking them via mouseclicks, or by pressing "T" ((un-)select all sets), "L" ((un-)select L4C, L5C), "I" ((un-)select all Pi cases) and "U" ((un-)select all Peanut cases). SkewbSkills is going to shuffle (randomize) the order in which they appear. Use the "Generate L2L Scramble" Button or press RETURN to generate a scramble. A drawing of the scramble appears. All scrambles are performed with the White/Red/Green Corner on top/front. Start the timer with the "Start" Button or press SPACE. After starting the timer, you can stop it again by clicking the same button ("Pause") or pressing SPACE again. You can than reset the timer to zero by using the "Reset" button (or press "R").
You do not need to change anything on any file anymore once you've extracted the folder. But: if you find that you'd like other scrambles to be displayed than the current ones, open any of the .txt-docs and modify the scrambles to your liking. If you want to keep track of which scrambles generate which case, see this document (credits: Elias Malomgré and Carter Cucala). I use the same terms for the cases to indicate them, as well as the same order.
Keep in mind that you need to write scrambles, not solutions for the different cases. You need to inverse your preferred solution to get the scramble you want. I chose the not so common solutions as scrambles, because than you can't see your solution by staring at the scramble and simply reading it backwards. That way you are forced to come up with a solution yourself. ;)
When modifying the scrambles in the .txt-Files, note that the very last character of the file must be one space in the line of the last scramble. So do not make any additional line break after the last scramble, but end the line of the last scramble with a space.
In almost the same manner, do not use a space or anything else to end the previous scrambles. All lines that are not the last line should only contain the scramble itself, ending with the last move. If you do not apply the steps above, your program might crash (because it can only read and use the scrambles provided in the form mentioned earlier).
As I am just starting out Python (and PyQt5), I had a lot of input from various online sources. I learned a lot from this playlist by Parwiz Forogh and also used this project by enkore to get the stopwatch running. Also thanks to Mattheo de Wit, who created a similar (but web-based) application! This was a big influence on how the L2L-Trainer should work.
When reading the LICENSE doc, you might find out that you are not only free to use the program, but also the source code. This is to ensure everyone can learn something, of course I appreciate every suggestion for improvement, as I might actually be the one to learn something through this project! :)
