Coin Flip

A genuine 50/50

Each flip is an independent random result — heads or tails, no memory of the last flip, no pattern to game. Flip once for a quick decision, or flip a batch and see how the tally lands over more tries.

Why a streak doesn't mean anything's "due"

Flipping five heads in a row feels like tails is "overdue," but each flip is independent of every flip before it — the odds of heads on the next flip are still exactly 50/50, regardless of the streak. That instinct has a name, the gambler's fallacy, and it's worth remembering any time a run of results starts to feel like a pattern. Over enough flips the tally above will drift close to even, but any single flip genuinely doesn't know or care what came before it.

A real coin isn't perfectly 50/50 — this one is

Physical coin flips have a small, well-documented bias toward landing on the same side they started on, caused by the physics of the flip rather than the coin's balance — research on the topic has put the effect at around 51% in favor of the starting side. A simulated flip like this one has no such bias baked in: it's a genuine, independently generated 50/50 result every time, with no "start face" to skew toward.

Why people still reach for a coin flip

A coin flip works as a decision tool specifically because it's fast, has no room for bias or favoritism, and produces a result nobody can argue is unfair after the fact — useful for anything from who goes first in a game to settling a genuinely 50/50 disagreement where deliberating further wouldn't actually improve the decision, just delay it.
