The case for a record
The complaint
The entry NextCall makes
Daily games get boring once there is nothing left to improve at
Accuracy is a rate, not a level, so there is nothing to finish. Three new questions open every UTC day, and each one that resolves moves your number.
Most prediction apps feel like a gambling app
Free to play, with no money or prizes. Nothing is bought, sold or risked here — a question shows you its resolution rule and the source it will be read from, and that is the whole of it.
There is no simple way to see if your instincts are actually good
One number, computed the same way for everyone: correct calls over questions that resolved. A correct call scores 100, an incorrect one scores 0, and a voided question scores nothing at all.
Today's three
Weather, space and science, and scheduled technology and culture events. Each one has a published figure or a scheduled moment behind it, which is what makes it scoreable without an argument.
Isobars, station reports and daily figures. A weather question is settled by the number a named station publishes, not by how the day felt.
Sample question
Will Denver record measurable snowfall on the game day?
Resolves against: Published daily station summary
Launch windows, orbital passes and lunar phases. Either the vehicle cleared the pad inside its window or it did not.
Sample question
Will the resupply launch lift off inside its primary window?
Resolves against: Operator launch log
Keynotes, releases and openings on a published schedule. The only question is whether the schedule held.
Sample question
Will the keynote begin within ten minutes of its published start?
Resolves against: Official event stream timestamp
Financial prices, elections and public office, sports, health and legal outcomes sit outside the launch categories and are never published as questions.
How a call becomes a result
Step 01
Three binary questions open for each UTC game day. Pick an answer, change it as often as you like, and the server decides whether your answer arrived in time. A device clock set far ahead or far behind has no say in it.
Step 02
At the stamped deadline the question closes for everyone at once. Nothing submitted afterwards counts, nothing already on record changes, and every revision you made stays readable in order.
Step 03
One person reads the declared source and attaches the evidence; a second person approves it. A correct call scores 100, an incorrect call scores 0, and a voided question scores nothing at all.
The part everyone asks first
You never pay to play, and nothing of value is ever awarded — not for a correct call, not for a streak, not for finishing first on a leaderboard. Points and accuracy are a record of how often you called an outcome correctly. They cannot be exchanged, transferred or redeemed for anything, and no money moves in either direction.
NextCall is not a prediction market and not a financial product. Nothing is bought, sold or risked, so there is nothing to lose except an argument.
Streaks start on the day you join
Confirm your age, get an anonymous identity, and make your first call. It takes about two minutes, and there is nothing to pay and nothing to install.
