How to play Daily Puzzle
One rule, one answer
Each sequence follows a single rule from one term to the next, and the answer is one specific number. There is no ambiguity to argue about, which matters more in a puzzle you cannot check against anything.
Two kinds of rule
Each term is either a fixed amount more than the last, or a fixed multiple of it. The rule is constant all the way along, so the third and fourth terms confirm what the second suggested rather than changing it.
The sequence itself is generated from the date
The starting value and the size of the step come from today's date, so the puzzle is the same all day and different tomorrow. Nothing is fetched and no server is involved.
It tells you where to look when you are wrong
A wrong answer comes back with a nudge — look at the difference between consecutive terms — rather than a bare 'no'. Enough to point at the right idea without giving the rule away.
No timer, no score
Nothing counts how long you took. Puzzles of this kind are meant to be thought about, and a clock would work against that.
Daily Puzzle Tips and Strategy
Take differences first
Write the difference between each pair of consecutive terms before anything else. A difference that stays the same means the sequence adds a fixed step, and the next term is the last one plus that step.
Divide to test the rest
If the differences keep changing size, divide each term by the one before it. A constant quotient means each term is a fixed multiple of the last, and applying that factor once more to the final term gives the answer.
Only two rules are used
Every sequence here is either a fixed step or a fixed multiple, held constant the whole way. That narrows the search: if neither fits, read the digits again instead of hunting for a more elaborate pattern, because there is not one to find.
Daily Puzzle — Frequently Asked Questions
Could the sequence have more than one answer?
The rule is a single fixed operation repeated along the whole sequence, and the answer is the one number that follows from it. That keeps it unambiguous by construction.
What if I cannot see the rule?
The wrong-answer hint points you at the difference between consecutive terms, which is where both rules are visible.
Why is it the same puzzle all day?
Because it is worked out from the date rather than drawn at random, and no server is involved.
Can I look at earlier days?
No. There is no archive — the same reasoning as the other daily puzzles, where a back-catalogue turns a habit into a backlog.
Does it need installing or an account?
No. It works offline and nothing is uploaded.
Daily Puzzle — Past Puzzles and Your Record
Any date can be rebuilt
The starting value and the step both come from the date, so a past date still produces the same sequence and the same answer. Missing a day takes the puzzle out of your view, not out of reach.
One key per finished day
Completion is a single local entry naming this puzzle and the date, and it is never uploaded. Clearing site data or switching devices empties that record while leaving every sequence exactly where it was.
Seven days shown at once
The strip above the sequence lists the last seven dates and marks the ones you answered. An empty cell means the day was not finished, not that the sequence has gone missing.
