Oh My Git! is an open-source game that teaches Git

Oh My Git! is an open-source game by bleeptrack and blinry that teaches Git with command cards, a live visualisation of the repository internals and a real Git behind the built-in terminal. GitLab’s PJ Metz put it first on a September 2022 list of Git resources for visual learners, as a card-based, gamified way into Git commands for early beginners. Cheaper than learning git reset --hard the hard way on a production repo.
