Coin Toss Series
Generate a configurable series of coin tosses locally with bounded controls and cryptographically secure browser randomness.
Ready. Your working data stays in this browser.
How it works
The browser validates this tool's limits and draws an unbiased binary value for every flip. Rejection sampling prevents modulo bias.
Practical example
Run Coin Toss Series with the sample controls, inspect the locally generated result, then copy or download only what you intend to keep.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
