Easy Pips answer — December 25, 2025

5 dominoes · 6×2 board · by Ian Livengood

Hint 1: where to start

Start with the 12 region at the left: the only way to make it with these dominoes is 6 + 6.

Hint 2: the pips in each region
  • the single-cell 2 region at the top-left: 2
  • the 12 region at the left: 6, 6
  • the 10 region at the bottom-right: 5, 5
  • the single-cell “>1” region at the bottom-left: 3
  • the single-cell “<1” region at the bottom-right: 0
Hint 3: step-by-step solution
  1. Row 1, column 1 has only one open neighbor, so its domino must run to row 2, column 1; the single-cell 2 region at the top-left needs a total of exactly 2 — nothing else fits. Place the 2–4 domino vertically on row 1, column 1 and row 2, column 1.
  2. The 12 region at the left needs a total of exactly 12 — 2 placements fit here for now, but every other one leaves some region impossible a few moves later. Place the 6–6 domino vertically on row 3, column 1 and row 4, column 1.
  3. The 10 region at the bottom-right needs a total of exactly 10 — 2 placements fit here for now, but every other one leaves some region impossible a few moves later. Place the 1–5 domino vertically on row 3, column 2 and row 4, column 2.
  4. The 10 region at the bottom-right needs a total of exactly 10 (1 of its 2 cells is already filled) — 2 placements fit here for now, but every other one leaves some region impossible a few moves later. Place the 0–5 domino vertically on row 5, column 2 and row 6, column 2.
  5. Row 6, column 1 has only one open neighbor, so its domino must run to row 5, column 1; the single-cell “>1” region at the bottom-left must total more than 1 — nothing else fits. Place the 1–3 domino vertically on row 5, column 1 and row 6, column 1.

9 dominoes · 5×6 board · by Ian Livengood

Hint 1: where to start

Start with the 10 region at the top-right: the only way to make it with these dominoes is 4 + 6.

Hint 2: the pips in each region
  • the “<3” region at the top-left: 0, 2
  • the “>3” region at the top: 1, 3
  • the 10 region at the top-right: 4, 6
  • the 5 region at the left: 2, 3
  • the 10 region at the right: 4, 6
  • the “<3” region at the bottom-right: 1, 1
  • the “=” region at the bottom-left: 1, 1
  • the single-cell 5 region at the bottom: 5
  • the “=” region at the bottom-right: 0, 0
Hint 3: step-by-step solution
  1. The 10 region at the top-right needs a total of exactly 10 — nothing else fits. Place the 6–6 domino vertically on row 1, column 6 and row 2, column 6.
  2. Row 3, column 6 has only one open neighbor, so its domino must run to row 4, column 6; the 10 region at the right needs a total of exactly 10 (1 of its 2 cells is already filled) — nothing else fits. Place the 1–4 domino vertically on row 3, column 6 and row 4, column 6.
  3. The “>3” region at the top must total more than 3 — nothing else fits. Place the 3–4 domino horizontally on row 1, column 4 and row 1, column 5.
  4. The “=” region at the bottom-right needs every pip to match — nothing else fits. Place the 0–5 domino horizontally on row 5, column 3 and row 5, column 4.
  5. The “=” region at the bottom-left needs every pip to match — nothing else fits. Place the 1–1 domino horizontally on row 5, column 1 and row 5, column 2.
  6. Row 5, column 5 has only one open neighbor, so its domino must run to row 5, column 6; the “=” region at the bottom-right needs every pip to match (1 of its 2 cells is already filled) — nothing else fits. Place the 0–1 domino horizontally on row 5, column 5 and row 5, column 6.
  7. The “<3” region at the top-left must total less than 3 — 4 placements fit here for now; this one matches the official answer (this board has more than one valid layout). Place the 1–2 domino horizontally on row 1, column 2 and row 1, column 3.
  8. Row 1, column 1 has only one open neighbor, so its domino must run to row 2, column 1; the “<3” region at the top-left must total less than 3 (1 of its 2 cells is already filled) — 2 placements fit here for now; this one matches the official answer (this board has more than one valid layout). Place the 0–3 domino vertically on row 1, column 1 and row 2, column 1.
  9. Row 3, column 1 has only one open neighbor, so its domino must run to row 4, column 1; the 5 region at the left needs a total of exactly 5 (1 of its 2 cells is already filled) — nothing else fits. Place the 0–2 domino vertically on row 3, column 1 and row 4, column 1.

This board has more than one valid layout; the steps follow the official answer.
