The micro crossword, properly introduced
Below the famous 5×5 mini sits an even smaller puzzle — the micro. A 3×3 or 4×4 grid, a handful of clues, and the same complete crossword experience compressed into the length of a red traffic light.
- 525 three-letter answers in the pool a 3×3 is filled from
- 1,494 four-letter answers, for when the 4×4 wants more room
- 3,336 hand-written clues between them — so a repeat word rarely wears the same clue
What counts as a micro?
There's no official rulebook — solvers simply use “micro” for anything smaller than a mini. Ours come in two flavours.
- 3×3 — nine squares
The puzzle at its theoretical limit. Crossword convention forbids two-letter answers, so a three-wide grid can't afford a single black square. What's left is one solid block of interlock: three across answers and three down, sharing all nine cells.
Every letter you write does double duty. Shapes like this have been admired since the Victorian word-square games.
- 4×4 — sixteen squares
Slightly relaxed: a pair of symmetric black corners, and room for four-letter words — a pool nearly three times deeper than the three-letter one.
Sixteen squares never felt so spacious.
Tiny grid, real teeth
Don't let the size fool you into casual guessing. Because every letter in a micro sits inside two answers, a single wrong entry immediately breaks something else — and in nine squares there's nowhere for a mistake to hide.
Treat every answer as provisional until a crossing agrees. It is the single most transferable skill in crosswords, and a micro drills it nine squares at a time.
Could the clue be answered by NAP or KIP? Don't commit — peek at the down clue sharing its first letter and let the grid cast the deciding vote. Learn that reflex here and you'll carry it up through every grid size there is.
Built fresh, on your device
There is no fixed list of puzzles behind this page. Each time you press New puzzle, a generator running in your browser fills the grid from a hand-curated pool of short words — everyday, satisfying words, not the dusty ERN-and-OLIO “crosswordese” that small grids usually lean on. Your browser remembers every puzzle it has dealt you and refuses to serve an exact repeat, and it also avoids grids that merely feel like recent ones. Individual words will of course resurface — English holds only so many friendly three-letter words — but they return in new crossings, usually wearing a different clue.
A puzzle sized for real life
The micro's genius is where it fits. It is a complete read-deduce-confirm-finish loop in the time it takes a kettle to warm up — which makes it the rare puzzle you can genuinely finish several times a day. The counter above the grid keeps your lifetime score (reveals don't count — we're honest here). Chain-solvers treat micros as a speed discipline: read the first across and first down clue together and see if you can finish before your toast does. And if the micro starts feeling roomy, the 5×5 mini is the natural next rung on the ladder.
The gentlest first crossword there is
Handing a crossword to a child, a student, or anyone convinced they “can't do crosswords”? Start here. Every convention of the grown-up grids appears in miniature — numbered squares, Across and Down, crossings that confirm each other — but with only six or so of everything, the first taste of success arrives inside a minute. And the most valuable lesson in solving (“stuck? check the crossing word”) takes ten seconds to demonstrate on a grid this size.
Print a pocketful
Micros may be the most printable puzzles on the site. Open Download a puzzle pack under the grid and you'll get a clean PDF of up to ten fresh grids — two per page, an answer key on its own sheet, optional name-and-date lines and large print. They're sized for the places big puzzles can't go: lunchbox notes, classroom early-finisher folders, the kitchen counter. Printed puzzles join your browser's repeat history too, so they won't reappear online later.
