Coin Flipper

A coin flip illustrates simple binary probability by assigning equal odds to two outcomes. This tool replicates that fairness digitally, delivering unbiased results through a cryptographically secure random source and clear visual feedback. You gain an immediate decision mechanism without relying on physical objects, useful wherever neutrality and transparency matter.

Behind the interface, a lightweight reactive engine animates a virtual coin, records every outcome, and instantly refreshes a donut chart that visualizes heads-to-tails distribution. All computations and graphics execute locally in your browser, ensuring no network latency, preserving data privacy, and delivering consistent performance across devices and varied screen sizes.

Resolve meeting deadlocks, classroom debates, or casual wagers by quickly and simply launching a single flip that everyone can observe in real time, gaining an authoritative result without dispute, then archive or reset the series for fresh rounds whenever needed; do not consider virtual flips legally binding in gambling or contractual scenarios.

Technical Details:

The codebase runs entirely client-side, combining a minimal HTML template, a reactive data layer, and a lightweight charting layer to draw dynamic visuals. Button events trigger high-entropy random generation, animate CSS classes, and update state that syncs with URL parameters, enabling session persistence without cookies or server interaction.

Instant Flip

The Flip Coin control calls a random generator, yielding heads or tails in under a millisecond before animation completes.

Animated Coin

CSS keyframes add rotational motion, giving users tangible feedback that mirrors the spin of a physical coin.

Stat Tracking

Aggregated counts update live badges to visualise totals and percentage distribution of heads versus tails.

Donut Chart

An on-the-fly chart renders proportional slices, resizing automatically on window changes to maintain legibility.

History Log

A scrollable list records every flip, indexed in reverse chronological order for quick back-reference.
