This PR adds my submission for the Soundness testnet gaming category.
Project: Sudoku zkApp
A zero-knowledge powered Sudoku puzzle game where players solve a grid and then generate a proof of correctness without revealing their solution.
The project demonstrates how Soundness can enable privacy-preserving gameplay and trustless leaderboards, proving validity of a puzzle solution without exposing the actual answers.
Future work will expand into multiple difficulty levels and potential ZK Sudoku tournaments.
