Welcome, dear skewb enthusiast!

You are most likely looking for SkewbSkillsWeb, a collection of training tools with which you can practice the first layer, advanced / algorithms, or one-looking. The offline (python) package is available here and comes in several releases. However, note that the web-based version is up-to-date, while the Python GUI is not maintained anymore.

Feel free to report bugs, send me your ideas or share your experiences!

For all German-speaking skewbers: this is my attempt to create a whole course / tutorial series! Mehrere Playlists und Zusatzmaterial sind bereits vorhanden!
