Hints and answers for November 3, 2025

Stuck? Take it in stages. A nudge costs less than the full answer, and the answer is here if you want it — each diagram below is the verified solution our generator built this board from, using tiles drawn from the standard double-six domino set. On the looser boards other valid arrangements can exist too; any filling that covers every square and satisfies every region counts as solved.

easy board — reveal the solution
Solved easy pips board for November 3, 2025: every domino placed with all region rules satisfied= 6= 15

Start with the "= 6" region. It spreads 6 pips across 4 squares, averaging 1.5 per square, so the halves that can legally sit there are limited before you have placed anything at all.

medium board — reveal the solution
Solved medium pips board for November 3, 2025: every domino placed with all region rules satisfied> 2= 6== 9> 1= 1

Start with the "= 1" region. It spreads 1 pips across 1 square, averaging 1.0 per square, so the halves that can legally sit there are limited before you have placed anything at all.

hard board — reveal the solution
Solved hard pips board for November 3, 2025: every domino placed with all region rules satisfied= 7any= 11> 2= 12= 8

Start with the "= 8" region. It spreads 8 pips across 3 squares, averaging 2.7 per square, so the halves that can legally sit there are limited before you have placed anything at all.

Board by board

easy

The easy board has 8 squares, 4 dominoes and 3 regions — 2 exact-sum and 1 all-different regions.

Start with the "= 6" region. It spreads 6 pips across 4 squares, averaging 1.5 per square, so the halves that can legally sit there are limited before you have placed anything at all.

medium

The medium board has 14 squares, 7 dominoes and 6 regions — 3 exact-sum, 2 greater-than and 1 all-equal regions.

Start with the "= 1" region. It spreads 1 pips across 1 square, averaging 1.0 per square, so the halves that can legally sit there are limited before you have placed anything at all.

hard

The hard board has 20 squares, 10 dominoes and 6 regions — 4 exact-sum, 1 greater-than and 1 unconstrained regions.

Start with the "= 8" region. It spreads 8 pips across 3 squares, averaging 2.7 per square, so the halves that can legally sit there are limited before you have placed anything at all.

Reading the tray first

The tray holds 3 doubles (3-3, 0-0, 6-6). Doubles contribute the same value twice, so they are the quickest way to overshoot an exact sum — place them where the arithmetic has room, not where it is tight.

The heaviest tile on the hard board is the 6-6 and the lightest is the 0-0. Those two are worth locating first: the heavy tile can only go where a sum has room, and the light one is often the only thing that fits a tight region.

What goes wrong on this one

With 2 of 6 regions only loosely bounded, this board resists arithmetic and rewards elimination. Work out where each tile cannot go before deciding where it should.

With 3 exact sums on the board, there is usually a square that only one tile in your tray can legally fill. Find that square first and the rest tends to cascade.

If you have genuinely stalled, undo back to the last tile you were confident about rather than reshuffling everything. Most dead ends on a board this size trace to one early placement made on a guess, and everything after it inherits the mistake.

About this date’s boards

Is the November 3, 2025 pips puzzle free to play?
Yes. All three boards for this date are free, with no account and no subscription, and they stay available permanently.
How many dominoes does the November 3, 2025 hard board use?
10 dominoes across 20 squares. Every tile in the tray must be used, and the count is always exactly half the number of squares.
Where do the doubles go on this board?
This tray holds 3 doubles (3-3, 0-0, 6-6). A double puts the same value on both of its squares, so it cannot sit inside an all-different region and it is the fastest way to overshoot a tight sum. Place them where the arithmetic has slack.
What do the regions with no badge mean?
1 region on the hard board carry no rule at all. Those squares still have to be covered, but any values may sit there — so fill them last rather than first.
Can I replay this puzzle later?
Yes. Boards are generated deterministically from the date, so this URL always shows this exact puzzle. Your progress saves in your own browser, and Reset clears it whenever you want a fresh attempt.

The badges on this board

The hard board uses 3 of the six possible region rules. What each one is actually demanding here:

= 7
Spreads exactly 7 pips over 2 squares, an average of 3.5 each. Anything that pushes the running total past 7 is already lost, so this is the region to count before you commit.
any
No constraint — these 5 squares just need covering. Fill them last; they absorb whatever the constrained regions reject.
> 2
Requires every value above 2, leaving only 4 of the seven pip values legal in those 2 squares.

The full badge vocabulary, including the ones this board happens not to use, is on the pips rules page.

How this board was made

This board was not hand-designed and it was not copied from anywhere. The generator laid down a valid arrangement of 10 dominoes first, then divided the 20 squares into 6 regions and derived each region's rule from the values that had already landed in it. Because the solution existed before the constraints did, this board provably has one.

It was then loosened: rules were swapped for weaker ones, one at a time, keeping each swap only while the number of valid arrangements stayed inside the bound for this difficulty. That is why 2 of the hard board's 6 regions carry something other than an exact total.

Generation is seeded from the date, so November 3, 2025 produces this exact board on every device, permanently. Sharing this link always shows the same puzzle. More on the process in our editorial policy.

Count the pips before you place

Your tray carries 51 pips in total, and the exact-sum regions between them demand 38 across 13 squares. That leaves 13 pips to absorb elsewhere. Running that subtraction before you place anything tells you whether the unconstrained squares are going to be a dumping ground or a tight squeeze.

The same check on the medium board: your tray carries 45 pips in total, and the exact-sum regions between them demand 16 across 6 squares. That leaves 29 pips to absorb elsewhere. Running that subtraction before you place anything tells you whether the unconstrained squares are going to be a dumping ground or a tight squeeze.

Why the shape matters here

This is a distinctly irregular outline, filling only 56% of its 6×6 bounding box. Narrow arms are the danger: a square at the end of a one-wide corridor has exactly one possible partner, so if that partner gets covered the board becomes unsolvable regardless of what else you do.

The easy board is a different animal: the shape fills about 89% of its 3×3 bounding box, so there are a few notches in the outline. Squares along those notches have fewer neighbours than they look like they do — check them before you commit tiles elsewhere.
