Game of Probabilities
Real statistics. Estimate the odds. Score by how close you get.
About Game of Probabilities
Game of Probabilities asks you to estimate a real-world percentage — how often something actually happens — and scores you on how close you land. Seven questions per round. Guess with the slider or type a number, submit, and the true figure is revealed alongside your points.
This is a calibration game rather than a knowledge quiz. You are not expected to know the exact figure; you are expected to know roughly where it sits, and to notice when your instinct is wildly off. Each question is worth up to a hundred points and the award falls away with the size of your miss, so a thoughtful estimate always beats a wild one.
Every question carries a source field. Where a figure is illustrative rather than sourced, the interface says so — the game does not present invented odds as real ones.
The miss is measured as a ratio, not a difference. Guessing two percent when the answer is four costs the same as guessing forty when the answer is twenty, because both are off by a factor of two. That is deliberate: for rare events, being out by a few percentage points is a large error, and the scoring should say so. Higher difficulties ask more questions, draw from a harder pool, and score the same miss more strictly.

How to win at Game of Probabilities
- Anchor, then adjust
- Start from a base rate you actually know and move from there. If you know roughly what share of adults drive, you can reason toward a narrower driving statistic instead of guessing from nothing.
- Distrust the round numbers
- Real-world percentages are rarely 50. When a question feels like a coin flip, that is usually your uncertainty talking, not the underlying rate. Commit to a side.
- Remember that vivid is not common
- Events that are memorable — dramatic, frightening, heavily reported — get overestimated badly. If a question describes something striking, your first instinct is probably too high.
- Read the exact population
- The wording matters enormously. "Of all adults" and "of adults who have ever tried it" produce completely different numbers, and most large misses come from answering a slightly different question than the one asked.
Game of Probabilities questions
- How many questions are in a round?
- Seven. Your total is the sum of the points scored on each one.
- How close does my guess have to be?
- A guess on the exact figure scores the full hundred points, and the award falls as the ratio between your guess and the answer grows. There is no fixed band; closer is always better.
- Where do the statistics come from?
- Each question carries a source field shown after the reveal. Figures that are illustrative rather than sourced are labelled as such in the interface.
- Do the questions change with difficulty?
- Yes. Easy asks five questions, Medium seven, Hard ten and Expert twelve, and the harder pools use less familiar statistics with stricter scoring.
- Is the daily set the same for everyone?
- Yes. The daily round is drawn from one shared seed, so every player answers the same questions in the same order for that date.
