flip
The oldest decision-maker there is, minus the coin. A cryptographically fair 50/50 every flip — with a running tally, because streaks are half the fun.
Fairer than a real coin
Physical coin flips aren't quite 50/50 — research on human flipping found a measurable bias toward the side that starts facing up (around 51%), driven by the physics of the toss. This flip has no physics: a cryptographic random bit, exactly 50/50, every time.
Streaks are normal — expect them
After five heads, the next flip is still exactly 50/50 —
the coin has no memory, and neither does this one.
The session tally above will drift from a perfect split constantly and drift back — that wobble is what real randomness looks like. A tally that stayed pinned at 50/50 would be the suspicious one.
Beyond two options
Multiple coins turn the flip into a mini-experiment (three coins: only a 1-in-8 chance of all heads). For decisions with more than two options, the random picker chooses from any list, and the dice roller covers 4 to 100 sides.
Coin flip FAQ
Yes — each flip is one cryptographically random bit, giving exact 50/50 odds. Physical flips have been measured at roughly 51/49 toward the starting face, so this is arguably fairer than a real coin.
Because streaks are what genuine randomness produces — a run of 6+ is more likely than not in 100 flips. Each flip remains 50/50 regardless of history; expecting tails to be 'due' is the gambler's fallacy.
Yes — up to 10 per press, each an independent fair flip, with the tally tracking everything since the page loaded.
No — nothing is stored anywhere, so refreshing resets the count. Every session starts clean and private.
