Online Wheel Tool

This tool provides a configurable online Glücksrad (wheel of fortune) to randomly select an entry from a user-defined list. It is designed for event organizers, educators, marketing teams, and community managers who need a transparent, reproducible draw for giveaways, contests, classroom activities, or prize drawings. Users define the options as wheel segments; the tool then assigns equal probability to each segment and returns a single winner when spun. The wheel’s data-driven design supports multilingual entries and auditable results.

Core logic & features: Accepts a list of strings as segments; supports a scalable number of entries; ensures uniform probability across all segments; provides deterministic sampling if seeded; outputs include the selected entry and metadata. Optional advanced controls allow configuring spin behavior and exporting results to JSON or text. The tool emphasizes fairness and traceability, enabling organizers to prove the selection process.

Inputs & outputs: Inputs include a list of labels and optional event metadata. Outputs include the chosen label, index, and a timestamp; machine-readable export options for audit. Algorithms & calculations: Uses a uniform RNG to map a random angle to a segment index; supports seed-based reproducibility; all segments receive equal angular probability. Error handling: Handles empty or duplicate lists with explicit errors; validates input length. Localization: Locale-agnostic; outputs in UTC by default. Assumptions & exclusions: Assumes distinct options; excludes UI-specific behavior and branding logic; not a full lottery compliance module.
