SpiniT is a web-based, arcade-style raffle and giveaway engine designed for live events and community dynamics. It allows users to load entrants, customize prize rounds, and execute high-tension draws powered by realistic physics, interactive visual effects, and synthesized audio. To ensure maximum transparency for audiences, SpiniT operates 100% client-side and utilizes cryptographic seed hashes to produce verifiable proof, social-ready Victory Cards (1080x1080), and official PDF certificates.
