Run independent 50/50 heads-or-tails draws
Choose the number of flips and run them together. The page lists each outcome and counts heads and tails; it does not force the totals to balance.
Concrete input and output example
Request 10 flips. A result of 7 heads and 3 tails is valid: each position had a 50% chance, while the batch total was free to vary.
How the result is produced
Each flip requests a Web Crypto-backed integer from a two-value range. One value maps to heads and the other to tails, independently for every position.
Limits and checks
- A single run allows 1–1,000 flips.
- Independence permits streaks and uneven batches; previous results do not change the next flip's probability.
- This is a mathematical two-outcome model, not a simulation of a particular physical coin or throwing technique.
Local data boundary
The requested count and outcomes remain in page memory and are not persisted by the tool. Nothing is uploaded unless you deliberately use an external copy or sharing action.
Questions about this tool
- Should 100 flips produce exactly 50 heads?
- No. Fifty is the expectation, not a required outcome.
- Does a long heads streak make tails due?
- No. Each new flip still has the same 50/50 model.
- Are the heads and tails totals calculated separately?
- The page counts the visible outcomes; tails is the batch size minus the heads count.
