Hints and answers for November 4, 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 4, 2025: every domino placed with all region rules satisfied= 20= 10

Start with the "= 10" region. It spreads 10 pips across 3 squares, averaging 3.3 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 4, 2025: every domino placed with all region rules satisfied< 6> 2= 11= 10= 17

Start with the "= 11" region. It spreads 11 pips across 3 squares, averaging 3.7 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 4, 2025: every domino placed with all region rules satisfied= 12= 12> 3= 14< 3> 5

Start with the "= 14" region. It spreads 14 pips across 5 squares, averaging 2.8 per square, so the halves that can legally sit there are limited before you have placed anything at all.

About this date’s boards

Is the November 4, 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 4, 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 (6-6, 1-1, 2-2). 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.
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.

Where this puzzle comes from

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 7 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 4 of the hard board's 7 regions carry something other than an exact total.

Generation is seeded from the date, so November 4, 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.

What each rule demands here

The hard board uses 4 of the six possible region rules. What each one is actually demanding here:

Forbids any repeat across its 2 squares. Note that this constrains values, not tiles — two different dominoes both contributing a 4 still breaks it.
= 12
Spreads exactly 12 pips over 3 squares, an average of 4.0 each. Anything that pushes the running total past 12 is already lost, so this is the region to count before you commit.
> 3
Requires every value above 3, leaving only 3 of the seven pip values legal in those 2 squares.
< 3
Caps every individual value below 3, which rules out roughly 57% of the pip values outright. It says nothing about the total.

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

The shape of the grid

This is a distinctly irregular outline, filling only 67% of its 5×6 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.

Where people get stuck

The all-different region is the one to watch. With 5 squares in the widest region on this board, an all-different rule quietly forbids far more arrangements than it looks like it does.

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.

Pip budget

Your tray carries 59 pips in total, and the exact-sum regions between them demand 38 across 12 squares. That leaves 21 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 55 pips in total, and the exact-sum regions between them demand 38 across 8 squares. That leaves 17 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.

Easy, medium and hard compared

These are three separate boards, not one board with hints removed, so playing all three on November 4, 2025 gives you three genuine attempts rather than three views of the same solution.

easy
8 squares, 4 dominoes, 3 regions, 2 region boundaries. 33% of its regions carry something other than an exact total, and the widest region spans 4 squares.
medium
14 squares, 7 dominoes, 5 regions, 6 region boundaries. 40% of its regions carry something other than an exact total, and the widest region spans 4 squares.
hard
20 squares, 10 dominoes, 7 regions, 11 region boundaries. 57% of its regions carry something other than an exact total, and the widest region spans 5 squares.

Start with the "= 11" region. It spreads 11 pips across 3 squares, averaging 3.7 per square, so the halves that can legally sit there are limited before you have placed anything at all.
