Daily Challenge — One puzzle a day
One short Python puzzle a day — the same one for everyone — and a streak to keep.
How it works
Every day there is one puzzle, chosen by the date, so everyone opening the page on the same day gets the same one. Solve it and your streak goes up. Miss a day and it starts again at one. Your streak lives in your own browser — there is no account and nothing is uploaded.
The puzzles run on a real Python interpreter, the same as every other game here, so your solution is genuinely executed rather than pattern-matched. Any correct answer passes; there is no single expected implementation.
Why a few minutes a day beats an occasional long session
Two things make practice stick, and both favour little and often:
- Retrieval. Producing code from memory strengthens recall in a way that reading it does not. One puzzle makes you retrieve; an hour of tutorial mostly makes you recognise.
- Spacing. The same total time spread over ten days beats one long sitting, because each gap forces you to reconstruct rather than remember.
The honest caveat: a daily puzzle is maintenance, not a curriculum. It keeps what you know sharp and shows you what has gone rusty. It will not teach you a topic you have never met — for that, work through the tutorials or the concept games, which take one subject at a time.
What the puzzles cover
They are drawn from across the language rather than one topic — string manipulation, list and dictionary work, counting, conditions, slicing and the occasional classic such as FizzBuzz, palindromes, anagrams and leap years. Each one is small enough for five or ten minutes and has a hint if you want it, with a worked solution after three attempts.
If you miss a day
The streak resets and that is all — nothing is lost and no level is locked. Streaks are a nudge, not a punishment, and a run of thirty is worth far less than the habit of coming back after breaking one. You can also press Try another one to work through the rest of the pool whenever you want more than today's.
When you want something longer, the other games each take a single topic through six levels, and the practice exercises have worked solutions.
Frequently asked questions
Is the daily Python challenge free?
Yes. It runs in your browser with no account and no install, and your code never leaves your device.
Does everyone get the same puzzle?
Yes. The puzzle is chosen by the date, so everyone opening the page on a given day sees the same one.
How is my streak stored?
In your own browser's local storage. Nothing is uploaded, so clearing site data or switching device starts it again.
What happens if I miss a day?
The streak goes back to one next time you solve a puzzle. Your best streak is kept, and nothing else is affected.
Can I do more than one puzzle a day?
Yes — press Try another one after solving. Only the first solve of the day counts towards the streak, but the rest of the pool is always available.
