A coin flip represents the simplest stochastic experiment, providing a one-in-two chance of landing heads or tails. Because each outcome is equally likely and independent of earlier trials, flipping a coin is widely used to illustrate fundamental probability concepts such as fairness, independence, and expected value in classrooms, decision making, and algorithm design.
This interactive tool lets you trigger unlimited virtual flips through a responsive button. A reactive engine instantly records each result, refreshes a donut distribution chart in a lightweight charting layer, and updates running totals and percentages. Because calculations happen locally, statistics refresh without delay, giving clear feedback on how randomness accumulates over successive trials.
Use it to demonstrate sample-size effects in probability lessons, settle friendly decisions, rehearse game theory scenarios, or inspect potential bias while calibrating physical coins. Outcomes are purely random and hold no monetary value; do not rely on them for wagering, contractual commitments, or any legally binding selection. Instead, treat every flip as an educational sample.
Follow these quick steps to explore randomness and observe distribution trends:
No. Results live only in your browser session and disappear when you refresh or close the page.
Each flip uses a cryptographically strong random function built into modern browsers, giving an equal 50-50 chance.
Thousands. Performance remains smooth because the reactive engine updates only small visual fragments on each toss.
No. The outcome is determined before the spin starts; the animation merely visualises that predetermined value.
