The puzzle page of a paper that doesn't exist.

puzlr prints a fresh set of ten puzzles every morning — crossword, sudoku, picross, cipher, slitherlink, hashi, kurosu, logic grid, anagram and word search — and throws them away by lunchtime. Every puzzle is proved to have exactly one solution before it's allowed on the page. The website is free and always will be; the app is for taking the grids somewhere with no signal.

Today's kurosu, live from the press.

This is the real thing, not a picture of it. Solve it here, or open it full size.

Today's kurosupuzlr.co.uk

Free, permanently

No accounts, no paywalls, no adverts, no tracking. The only ask on the whole site is an optional Ko-fi link in the footer.

Graded honestly

Difficulty tiers are measured by actually solving the puzzles, and each bank is deep enough that no tier repeats more than twice a year.

One solution, proved

Every published grid is checked by search to have a unique answer — a wrong “well it could also be…” is treated as a defect, not a shrug.

On the App Store

The same ten grids are set for the touchscreen in puzlr for iPhone and iPad. Every puzzle ships inside the app, so it plays on a plane or down the Tube, and it counts the days you don't miss where nobody else can see it. £3.99 once, no subscription. The website is unaffected: still free, still nothing to sign into.

Privacy: no accounts, no adverts and no tracking on the website or in the app.

Ten minutes.
No allegiance required.

A fresh set every morning, free in the browser, and the same ten in your pocket when there's no signal.
