The backend engine powering Overdle — the ultimate Overwatch guessing game.
Overdle is a daily challenge game inspired by the popular Valdle, but completely dedicated to the Overwatch universe. Every day, players are challenged to identify a hero based on specific clues such as Affiliation, Role, Launch Year, and Many more.
If you are looking for the source code for the Next.js application, you can find the repository here: 👉 OverDaily Frontend Repository
The frontend is live! You can test your knowledge right now at:
This API serves as the backbone of the application. It is designed to be robust and performant, managing the entire game state and data distribution.
Key Responsibilities:
- Data Management: Orchestrates the database of Heroes, Abilities, and Voice Lines.
- Daily Challenges: Generates and serves the daily puzzle data to the frontend.
- Consistency: Ensures game integrity and validates user answers.
We are constantly working to expand Overdle. Here is what's coming next:
- Ability Mode: A new mode to guess the hero based solely on ability icons or descriptions.
- Voice Line Mode: Challenge your hearing by identifying heroes from obscure voice lines.
- Map Guessing: A visual mode to guess the Overwatch map from a screenshot.
- Ultimate Mode: A specialized mode focused entirely on Ultimate voice lines and sounds.
This project leverages modern software architecture, utilizing Java 21 and Spring Boot 3 for high performance, alongside Redis for caching and Next.js for the client-side experience.
