🎲 Randomizers & Generators
Flip a virtual coin and track Heads and Tails results.
Flip a simple virtual coin when you need a quick two-way random choice. Fieldlet tracks the current session's Heads and Tails totals.
Simulate a fair two-sided coin for simple choices, probability demonstrations, and game setup. Each flip is independent, and a multi-flip summary makes short runs easy to inspect.
The selection runs in the browser and the entered list is not sent to Fieldlet. Agree on eligibility and reroll rules before using randomness with a group.
Last reviewed for accuracy:
Scenario: A class runs ten simulated flips and sees six heads and four tails.
Result: Heads occurred 60% in that short sample, although each individual flip still had a 50% chance.
The observed proportion can differ from one half in a small run. The generator gives each flip the same independent binary probability.
The browser random source is mapped to one of two outcomes. Independence means the previous result is not used to adjust the next one, so streaks are allowed.
A fair process gives heads a one-half probability on each flip, but a short sample can be uneven. The history and summary describe what happened in that run; they do not force the next flip to compensate.
Yes. Previous flips do not alter the probability of the next result.
No. With independent flips, the next outcome remains 50–50 regardless of the preceding streak.
