Guides
Can't decide? Let chance settle it. This tool works like a coin flip dedicated to yes-or-no questions: pick how many answers you need and get an instant, unbiased Yes or No for each one — no coin, no app, just your browser.
What does this generator do?
It produces one or many random Yes/No answers using your browser's random number generator. By default every answer has an equal 50/50 chance of landing on Yes or No, exactly like flipping a fair coin. Need more than a single answer? Set the count higher and get a whole batch at once, along with a quick summary showing how many came out Yes versus No and the resulting percentages.
Bias the odds
Most yes/no questions are genuinely 50/50, but not all decisions are meant to be even. The Chance of Yes slider lets you skew the odds — set it to 70% and Yes will come up roughly seven times out of ten, set it to 20% and No becomes the likely outcome. Leave it at 50 for a perfectly fair flip.
Common uses
- Quick decisions — settle a "should I or shouldn't I" question instantly.
- Games and icebreakers — resolve a tie, decide who goes first, or add a random twist to a game night.
- Testing and sampling — generate batches of boolean-style test data, optionally weighted toward one outcome.
- Habit and behavior nudges — bias the odds toward "Yes" to give yourself a gentle push toward following through on something.
How to use it
- Set how many answers you want — 1 for a single flip, or up to 100 for a batch.
- Adjust Chance of Yes if you want the odds skewed away from a fair 50/50 split.
- Press Flip. Press it again anytime for a fresh result with the same settings — copy or download the list.
Is it truly random?
Results come from your browser's pseudo-random number generator, which is more than good enough for decision-making, games, and sampling. It is not intended for cryptographic or security-sensitive use — for that, use a dedicated cryptographically secure generator.
