Frequently asked questions
Is it really 50/50, or does it favor heads?
Exactly 50/50. The flip uses cryptographic rejection sampling, which means each side has exactly 50.0% probability — no favoring of heads, no bias toward whichever side you flipped last. The same RNG primitive powers every Plinkr random tool, so the fairness guarantee is consistent across the site.
Can I link to a specific flip result to show someone?
Yes. The result lives in the URL state after a tap, so you can copy the address bar and send the link to anyone. They will open the page and see the same coin already flipped to the same result. Useful for settling "did the coin really land on heads?" disputes — proof in URL form, no screenshot editing required.
Is this for gambling or sports betting?
No. Plinkr is for casual decisions only — settling who pays for coffee, who picks the show, who goes first. There is no real-money mode, no payout, no integration with any betting platform. The phrase "coin flip" overlaps with gambling search intent, but Plinkr's tool is firmly on the casual-decision side of that line.
Is each flip recorded anywhere, or is there a flip history?
No. Each flip happens entirely in your browser; nothing is sent to a server, no log is kept. The flip result is in the URL state on your tab, but that URL is local to you until you copy-paste it somewhere. There is no Plinkr account, no flip history, no "recent flips" feed visible to anyone.
