Coin Flip Simulator

Coin Flip Simulator

The simulator performs from 1 to 10,000 flips per run, with 10 selected initially. Users can replace the two output labels; blank fields fall back to the page's default heads and tails labels.

Each flip draws a cryptographic 32-bit random value in the browser and maps an unbiased accepted value to one of two equally likely outcomes. There is no probability-weight control or seed setting. A later random run may happen to match an earlier one.

The output lists every flip in order, then reports totals for both labels. For 10 flips a valid result might contain 6 heads and 4 tails, but a 5/5 split is not guaranteed in a small sample.

Totals count the actual random outcomes independently of label text. Identical labels still produce correct totals, but distinct labels are recommended so the sequence and two summary rows can be understood.

Generation is local to the current browser and requires no uploaded data. This is a simulation for examples and informal decisions, not an auditable draw, gambling service or proof of physical randomness.
