NYT Pips Answers for December 10, 2025
NYT Pips answers for December 10, 2025, a Wednesday: hints first, then the full solution for the easy, medium and hard boards. Take the hints in order and stop when you have enough — nothing below is revealed until you open it.
Today's set runs from a 10-square easy board to a 20-square hard one, a gap of 10 squares, with the hard board carrying 1 double against easy's 1 and 4 loose regions against 3. Constructed by Ian Livengood.

Easy — 10 squares, 5 dominoes
60% of the regions on this board are loose — comparisons or unconstrained — so there is little to calculate from and most of the work is deciding where tiles cannot go.
At 10 squares this is a typical easy board — the average is 9.9 — so nothing about its size explains an unusually long or short solve.
60% of its regions are loose against a norm of 40%, so this board is vaguer than usual — there is less exact arithmetic to anchor on and more reasoning by elimination.
Its tightest sum target is 1, against a median of 5 across every board published. A target that low forces blanks and low values, and is usually the fastest way in.
Hint 1 — where to start
Start with the = 1 region — the top left single square — where the pips in this region must add up to exactly 1. Work there first because exactly one combination of values can fill it, so it is fully forced before you place anything.
Hint 2 — what your tray forces
The tray carries 1 double: 5-5. Neither all-equal nor all-different regions appear today, so the doubles are unusually free — place them last.
Hint 3 — the opening region's values
The = 1 region resolves to 1. Which half of which domino supplies each is still yours to work out.
Full answer — easy board, December 10, 2025
| Region | Where | Values |
|---|---|---|
| = 1 | the top left single square | 1 |
| = 30 | the top centre 6-square block | 5, 5, 5, 5, 5, 5 |
| > 3 | the top right single square | 4 |
| < 3 | the bottom centre single square | 2 |
| no rule | the bottom centre single square | 3 |
Every tile and the squares it covers
- 1-5 → row 1 col 1 and row 1 col 2
- 2-5 → row 3 col 3 and row 2 col 3
- 3-5 → row 3 col 4 and row 2 col 4
- 4-5 → row 1 col 6 and row 1 col 5
- 5-5 → row 1 col 3 and row 1 col 4
Rows and columns are counted from the top-left of the board, starting at 1.
Medium — 18 squares, 9 dominoes
The = 0 region is the giveaway: a target that low forces blanks and ones, and almost nothing else fits.
At 18 squares this is 22% larger than the average medium board, which runs 14.8. More squares means more placements to keep straight at once, and a mistake made early sits underneath more correct-looking work before you find it.
13% of its regions are loose against a norm of 42%, so this board is tighter than usual — more regions hand you a number outright, which is why it may have felt unusually tractable.
Its tightest sum target is 0, against a median of 5 across every board published. A target that low forces blanks and low values, and is usually the fastest way in.
Hint 1 — where to start
Start with the = 3 region — the top right single square — where the pips in this region must add up to exactly 3. Work there first because exactly one combination of values can fill it, so it is fully forced before you place anything.
Hint 2 — what your tray forces
The tray carries 2 doubles: 5-5, 4-4. A double is the only tile that fits wholly inside an all-equal region, and there are 3 here.
Hint 3 — the opening region's values
The = 3 region resolves to 3. Which half of which domino supplies each is still yours to work out.
Full answer — medium board, December 10, 2025
| Region | Where | Values |
|---|---|---|
| = 3 | the top right single square | 3 |
| > 3 | the middle left single square | 4 |
| = | the middle centre row of 3 | 4, 4, 4 |
| = 30 | the middle left 6-square block | 5, 5, 5, 5, 5, 5 |
| = 0 | the middle right single square | 0 |
| = 7 | the middle right column of 2 | 6, 1 |
| = | the bottom left row of 2 | 3, 3 |
| = | the bottom centre row of 2 | 0, 0 |
Every tile and the squares it covers
- 5-5 → row 4 col 2 and row 4 col 3
- 4-4 → row 2 col 3 and row 2 col 4
- 0-3 → row 5 col 3 and row 5 col 2
- 6-5 → row 4 col 5 and row 4 col 4
- 4-5 → row 2 col 1 and row 3 col 1
- 4-3 → row 2 col 5 and row 1 col 5
- 5-0 → row 3 col 4 and row 3 col 5
- 0-1 → row 5 col 4 and row 5 col 5
- 3-5 → row 5 col 1 and row 4 col 1
Rows and columns are counted from the top-left of the board, starting at 1.
Hard — 20 squares, 10 dominoes
Two or more regions carry no rule at all today, which sounds generous and is not: unconstrained squares give you nothing to reason from, so the 2 sum regions have to carry the whole board.
At 20 squares this is 23% smaller than the average hard board, which runs 26.1. A smaller grid is more forgiving: a bad tile is fewer undos away from being fixed.
44% of its regions are loose against a norm of 29%, so this board is vaguer than usual — there is less exact arithmetic to anchor on and more reasoning by elimination.
The tray holds 1 double against a typical 3.11. Doubles are the most constrained tiles you can be dealt, so you get fewer of the free constraints doubles normally provide, and have to find your footholds elsewhere.
Its tightest sum target is 9, against a median of 4 across every board published. A high target forces large values into a small space, which narrows the options just as sharply from the other direction.
Hint 1 — where to start
Start with the > 4 region — the bottom centre single square — where the pips in this region must add up to more than 4. Work there first because only 2 combinations of values can fill it.
Hint 2 — what your tray forces
The tray carries 1 double: 6-6. A double is the only tile that fits wholly inside an all-equal region, and there are 3 here.
Hint 3 — the opening region's values
The > 4 region resolves to 5. Which half of which domino supplies each is still yours to work out.

Questions about this day
- What is the answer to NYT Pips on December 10, 2025?
- The full solution for all three boards is on this page, below the hints. Two or more regions carry no rule at all today, which sounds generous and is not: unconstrained squares give you nothing to reason from, so the 2 sum regions have to carry the whole board.
- Can I see a hint without seeing the whole answer?
- Yes. Each difficulty has three hints in order — where to start, what your tray forces, then the values in the opening region — each behind its own disclosure, with the full solution last. Nothing is revealed until you open it.
- Are these the official New York Times boards?
- The puzzle data is the Times’ own, and this page reports and explains the solution. EnergyPips is not affiliated with The New York Times, and the boards are not reproduced here to play — to play, go to the Times. To play a free daily domino puzzle of our own, the rest of this site is that.
- Why is the hard board harder than the easy one?
- On December 10, 2025 the hard board runs 20 squares across 9 regions against the easy board’s 10 and 5, and carries 4 regions that give you no exact number to work from.
