Is the result truly random?

Yes — the tool uses Math.random(), which is a cryptographically non-deterministic pseudo-random number generator in modern browsers. It is fair enough for everyday decisions and games.

What does the bias slider do?

It sets the probability that the result is "Yes". At 50% the odds are equal. Slide to 70% and Yes will appear roughly 70% of the time. The current probability is shown next to the slider.

Does the tool remember my answers?

The session history is kept in memory while the page is open. It is not saved to localStorage or sent to any server. Refreshing the page clears it.

Can I use this as a coin flipper?

Absolutely — keep the bias at 50% for a perfectly fair 50/50 flip, just like a real coin.

How many times can I generate?

There is no limit. You can click as many times as you like in a single session. The history panel keeps the last 20 results.
