11×11 Queens puzzles — unlimited practice

A fresh 11×11 board whenever you want one, at any difficulty, with 330 finished 11×11 boards behind this page. It is past the end of the daily ladder — nothing on the calendar is this big. Place 11 queens: one in every row, one in every column, one in every colour, and no two touching — corners included. Change the difficulty with the pill beside the board, switch size from the Unlimited tab, and keep going: no daily limit, no streak to protect, no clock you have to beat.

What an 11×11 Queens board asks of you

A hundred and twenty-one squares and eleven colours. At this width the first queen can take a while to arrive, and that is not the board resisting: it is simply wide, and the opening is somewhere in it. Every technique you need here was learned on a smaller grid. What is new is the search.

Which technique opens the board is what the difficulty pill beside it really changes. The strategy guide works through each named technique in the order the solver reaches for them, and the hint button on this board names the same ones.

Difficulty at 11×11 is a claim about the reasoning

The label never describes the square count — every board on this page has the same 121 squares. It describes what a board demands before it gives up its first queen, and the two move independently: an 11×11 rated beginner can be a shorter read than a 5×5 rated hard, 96 extra squares and all. The Queens Unlimited hub makes the same case with two real boards side by side.

Beginner — 60 boards. One region already holds a single square, so the first queen is free and the rest falls to counting rows, columns and colours. That one gift is deliberate: from an empty grid the simplest techniques have nothing to bite on without it.
Easy — 120 boards. Opens on a colour confined to one row or column. It owns that line, everything else in the line is dead, and the 11×11 comes apart from there.
Medium — 120 boards. Several of those confinements chained together, each one visible only after the last has been marked off — which across 121 squares means marking is part of the technique, not tidying up after it.
Hard — 30 boards. Pigeonhole arguments spanning several of the 11 regions at once, plus the exclusion reasoning that rules a square out by showing what it would break.

Easy. At this width even an easy board is a long board, and the size itself is the new variable — add the hard reasoning once the length has stopped being the problem.

Practising at 11×11

Treat the first pass as reconnaissance rather than a failure. One full sweep that places nothing but marks everything forced is worth more on an 11×11 than three impatient partial ones.

Two things hold at every size. A hint never guesses: it finds the next move a person could justify, names the technique, and waits for you to press show me before it marks anything. And boredom means move up a difficulty, not a size — the same reasoning with more squares around it is not new practice. The hub page has the full method.

Every 11×11 board here is provably fair

Each one was checked twice: once for having exactly one solution, and once for being reachable from an empty grid without a single guess. The check reruns over the whole pool before every release, so it covers all 330 11×11 boards rather than the handful anybody happened to play. If you are stuck here, there is a next step and the hint can name it.

Where 11×11 sits

No daily mode reaches 11×11. This size exists for practice and for nothing else.

Daily Mini — three boards a day, 6×6 to 8×8. The one that carries a streak.
Daily Max — ten boards a day, climbing to 10×10 and finishing harder than the Mini ever gets.
Archive — every past day, still playable and still scored the same way.
10×10 practice — one step down, if 11×11 is currently more search than reasoning.
12×12 practice — one step up, once 11×11 at hard has stopped surprising you.

Questions people ask about 11×11 Queens puzzles

How many queens does a 11×11 board take?: 11 — one per row, one per column, one per colour. There are always exactly 11 colours, and no two queens may touch, corners included.
Is 11×11 harder than a smaller board?: Bigger, not necessarily harder. Difficulty here describes the reasoning a board demands. A large board with generous regions can fall to counting alone, while a small one can need an argument spanning several regions at once.
How many 11×11 Queens puzzles are there?: 330 in the pool for this size, split across the four difficulties — 60 beginner, 120 easy, 120 medium, 30 hard. The picker avoids repeats within a session, so you will not see the same 11×11 twice in an evening.
Which difficulty should I start with on 11×11?: Easy. The width is already the new variable; do not add two at once.
Do these count towards my streak?: No. Streaks come from the daily boards. Practice is for drilling, so nothing here can break a run — or build one.
Can I play a 11×11 board on a phone?: Yes. The board sizes itself to the screen, so it stays tappable one-handed. If colour is not a reliable channel for you, turn on high-contrast colours in Settings and the regions separate by lightness instead of hue.
