NebulaSketch
Real-time multiplayer drawing game with WebSocket-driven low-latency interaction. Uses Redis for session management and fuzzy matching for guess validation.
Overview
NebulaSketch is a fast-paced multiplayer drawing and social deduction web application engineered for zero-lag collaboration. Players draw prompts on an interactive HTML5 canvas while others guess the secret word in real time. The platform synchronizes vector brush strokes and canvas actions across clients using bidirectional WebSockets with sub-50ms latency. Redis powers the in-memory room state, turn rotations, and session management, while a Levenshtein-distance fuzzy string matching algorithm intelligently evaluates guesses to reward near-misses without spoiling the solution.
