    What it does

    Exactly even
    A real coin can favour the side it starts on; this one is drawn from your browser’s cryptographic random source, half and half.
    Many coins at once
    Toss ten or two hundred together and see how many landed heads, plus the longest run of one side.
    Settles arguments on the record
    Every toss is in the history with its time, ready to copy or download.

    Questions

    Is an online coin flip really 50/50?

    This one is. Each coin is one whole number, 0 or 1, from the cryptographic random source, drawn so neither value is even slightly likelier. Over many tosses the count drifts around half and half, as a fair coin should.

    I got heads five times in a row. Is it broken?

    No — runs like that are normal. In 100 tosses, a run of five or more of the same side happens most of the time. Toss 100 coins at once and the “longest run” line shows how long they get.

    Can I flip several coins at once?

    Yes, up to 200. The page shows each coin, how many came up heads and tails, and adds the whole toss to the count.
