This project is a modern GNOME port of the concept presented in ByteSebs's tutorial video, originally built with older technologies. Since that tutorial is now outdated (which demonstrates how fast these technologies can evolve!), I decided to recreate it using current GNOME ecosystem tools.
Instead of the classic Rock-Paper-Scissors, I implemented the Rock-Paper-Scissors-Lizard-Spock variant (popularized by The Big Bang Theory), as a spiritual reimplementation of a project I made early in college.
This is a study project focused on learning GTK4, Libadwaita, and Python integration with GNOME, keeping the code simple and readable.
The rules are simple:
- Rock crushes Scissors and Lizard
- Paper covers Rock and disproves Spock
- Scissors cuts Paper and decapitates Lizard
- Lizard eats Paper and poisons Spock
- Spock vaporizes Rock and smashes Scissors

- Python 3.12+
- GTK 4
- Libadwaita 1.8+ (GNOME 49)
- Blueprint Compiler
- Meson build system
The easiest way to install Duel! on any Linux distribution is via Flathub:
Click here to install from Flathub
Alternatively, use the terminal:
flatpak install flathub io.github.lloura.DuelPy
flatpak run io.github.lloura.DuelPy- Install GNOME Builder
- Clone this repository:
git clone https://github.com/lloura/DuelPy.git- Open the project in GNOME Builder
- Click the Run button at the top
Pre-built Flatpak packages are also available in the Releases section.

This project was an excellent opportunity to:
- Experiment with GTK4/Libadwaita principles and design patterns
- Get hands-on experience with GNOME Builder as an IDE
- Learn Python-GObject integration and PyGObject bindings
- Understand the Meson build system and Flatpak packaging
- Apply GNOME Human Interface Guidelines to create a modern UI
I chose Python because I plan to use it for similar projects in the future, and this served as a solid foundation for understanding the GNOME development ecosystem.
- Basic game functionality
- Persistence with GSettings
- Implementation of a visual 'How to Play' guide for the different variants
- Implementation of David C. Lovelace's RPS-7 mode
- Flathub submission (Done! 🎉)
- Add more game variants (RPS-9, RPS-11...)
Contributions are welcome! Feel free to open issues or submit pull requests.
Game Variants:
- RPSLS created by Sam Kass and Karen Bryla.
- RPS-7 and others created by David C. Lovelace.
Inspiration:
- Originally inspired by ByteSeb's Duel & Tutorial Video and a previous college project.
