lottery

lottery is a browser-based lottery drawing program designed for company annual meetings and event prize draws. It gives organizers a visual way to select winners from a participant pool. The workflow lets users choose a draw size, start the lottery animation, and stop it to generate the final results. It supports draw sizes such as 30, 10, 5, 2, or 1 winner at a time. After a participant wins, the app marks that person so they are not selected again in later rounds. It also includes an interactive sphere-style display that can be zoomed in or out with the mouse wheel, making it feel more dynamic for live events.

Features

Selectable winner counts for each round
