Game rules
How NextCall works
Every rule that decides a point, a deadline or a result is on this page, published before the questions it governs.
NextCall never awards money or prizes
You never pay to play, and nothing of value is ever awarded — not for a correct call, a streak, or first place.
Points and accuracy are a record, not currency. They cannot be exchanged, transferred or redeemed.
Free to play, with no money or prizes. Funded by display advertising. Nothing is bought or sold here.
Who can playThe minimum age, and the anonymous identity confirming it creates
NextCall is for adults at or above the minimum age in force where you are.
- The minimum age
- Policy configuration, not a number in this page, because it differs by jurisdiction. The eligibility page shows the figure that applies to you.
- Confirming your age
- Creates an anonymous identity on the server
- Never asked for
- An email, a name, a password, or a date of birth
- Under the minimum
- Read every question, result and source; answer nothing
A second identity gains you nothing, because nothing of value is ever awarded.
The daily setThree binary questions for each UTC game day
Three questions are published for each UTC game day, and every one is binary.
- Each question
- Two answers, exactly one of which will be true once the outcome is observable
- How many to answer
- All three, or only the ones you have a view on
- Printed on the card
- Its category, its deadline, the rule that resolves it, and the source that rule reads
- Published
- All four before you answer, never after

Deadlines and revisionsThe server clock decides, and you can revise until it does
Every question prints its own deadline, stamped in UTC — for example Locks 23:59 UTC.
- The deciding clock
- The server's. A device clock set far ahead or far behind changes nothing
- An answer at or after it
- Rejected. Whatever was already on record stands
- Until the deadline
- Change your answer as often as you like
- Each change
- Appended to your history rather than replacing it, so both readings stay
- After the fact
- Nothing is rewritten
Scoring100 points for a correct call, 0 for an incorrect one
Scoring policy
exact-v1- Correct call
- 100 points
- Incorrect call
- 0 points
- Voided question
- No scoreExcluded from points and from your accuracy
- Question you did not answer
- No scoreExcluded from your accuracy
- Accuracy
- accuracy = correct / resolved answered calls — voided questions and questions you did not answer are excluded.
- Your daily score
- The sum of the points from that UTC game day
- The policy
- Versioned, so an old score can always be recomputed under the one that produced it
- Not available at any price
- Multipliers, confidence bonuses, purchases, or anything an advertisement can change
Resolution and evidenceA named source, attached evidence, and two people
The rule comes first: nobody can move the target after you answer.
- Before a question opens
- A plain-language resolution rule, a named primary source, and its void criteria
- Once it closes
- A resolver reads the declared source and attaches the evidence
- The evidence
- What was observed, where it was published, and when it was captured
- Bound to
- The exact version of the question you answered
- Approval
- One person proposes the resolution; a different person approves it
- An ambiguous, late or silent source
- The question stays pending or is voided. An outcome is never guessed
- A pending result
- Says so plainly, rather than showing a placeholder answer
- A correction
- Creates a new resolution version and a new score version
- Earlier scores
- Marked superseded rather than erased; leaderboards rebuild from the active scores
- If it touches your call
- A correction notice in the product names what changed, and when
Voided questionsVoid criteria published in advance, and what a void leaves
Every question publishes its void criteria next to its resolution rule.
- What you know in advance
- Exactly what would make this question unanswerable
- For example
- A station that never publishes its daily figure; an event postponed past its window; a source that contradicts itself
- A voided question
- Scores nothing
- Your points and accuracy
- Both exclude it. Your record is exactly as it was
- Your participation streak
- Unbroken, for a player who answered in good faith
- The reason for the void
- Published with it
Leaderboards and streaksDense ranking, and what a streak actually measures
Leaderboards cover the game day, the configured UTC week and all time.
- Ranking
- Dense: exact ties share a rank, and the rank after a tie is not skipped
- Weekly and all-time
- Need a minimum number of resolved calls, so a single lucky day cannot top the table
- A participation streak
- Counts the days you answered at least one question. It measures showing up, not accuracy
- Protecting a streak
- There is nothing to buy, and nothing is said to shame you when one ends
- Absent from public rows
- Profiles that are restricted, deleted, or opted out
- Produced by a leaderboard, a streak or a badge
- Nothing of value, at any point
What NextCall is notNot a market, not a financial product
NextCall is not a prediction market and not a financial product.
- Bought, sold, exchanged or risked
- Nothing, in either direction
- Points
- Have no monetary value, cannot be transferred, and cannot be redeemed
- Never the subject of a question
- A market price, or an advertiser
- An advertiser's influence on a resolution
- None
- What you are playing for
- A record of how often you called an outcome correctly
AdvertisingLabelled slots that never gate a question or a result
Display advertising pays for the game, which is how it stays free.
- Every ad slot
- Labelled as an advertisement
- Reserved space
- Held, so the page never jumps
- Placement
- Well away from the answer controls
- Gating a question, an answer or a result
- An advertisement never does
- If a slot does not fill
- It collapses, and play continues
- An advertiser's say
- None, in which questions publish, how they resolve, or who ranks where
Your record and your dataExport, deletion, and what a share card shows
Your identity starts anonymous, and linking an email is optional.
- Why link one
- To carry your record to a second device. Your existing calls stay attached to you
- Export or deletion
- Request either at any time from privacy choices. Neither stops you answering today's questions while it is processed.
- Consent choices
- Live in settings.
- A share card shows
- A date, a correct count, a total, points and a streak
- A share card never shows
- An email, an internal ID, a location, an age, or any answer before its deadline
Read the rules in action
An open question shows its rule and its source before you answer. A resolved one shows the evidence.
