Easy Pips answer — October 22, 2025

4 dominoes · 3×3 board · by Heidi Erwin

Hint 1: where to start

Start with the 6 region at the bottom-left: only 1 + 5, or 2 + 4 can make it with these dominoes.

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

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

12 dominoes · 8×4 board · by Rodolfo Kurchan

Hint 1: where to start

Start with the 30 region at the bottom-left: the only way to make it with these dominoes is 6 + 6 + 6 + 6 + 6.

Hint 2: the pips in each region
  • the single-cell “<5” region at the top-left: 4
  • the “=” region at the top-right: 1, 1, 1, 1
  • the “=” region at the left: 2, 2, 2, 2
  • the “=” region at the right: 3, 3
  • the “=” region at the right: 0, 0
  • the 30 region at the bottom-left: 6, 6, 6, 6, 6
  • the “=” region at the bottom-right: 4, 4
Hint 3: step-by-step solution
  1. The 30 region at the bottom-left needs a total of exactly 30 — 2 placements fit here for now, but every other one leaves some region impossible a few moves later. Place the 6–6 domino horizontally on row 8, column 1 and row 8, column 2.
  2. The 30 region at the bottom-left needs a total of exactly 30 (2 of its 5 cells are already filled) — 3 placements fit here for now, but every other one leaves some region impossible a few moves later. Place the 2–6 domino vertically on row 6, column 1 and row 7, column 1.
  3. The “=” region at the left needs every pip to match (1 of its 4 cells is already filled) — nothing else fits. Place the 2–2 domino vertically on row 4, column 1 and row 5, column 1.
  4. Row 7, column 2 has only one open neighbor, so its domino must run to row 7, column 3; the 30 region at the bottom-left needs a total of exactly 30 (3 of its 5 cells are already filled) — 2 placements fit here for now, but every other one leaves some region impossible a few moves later. Place the 4–6 domino horizontally on row 7, column 2 and row 7, column 3.
  5. Row 8, column 3 has only one open neighbor, so its domino must run to row 8, column 4; the 30 region at the bottom-left needs a total of exactly 30 (4 of its 5 cells are already filled) — nothing else fits. Place the 5–6 domino horizontally on row 8, column 3 and row 8, column 4.
  6. The “=” region at the top-right needs every pip to match — 2 placements fit here for now, but every other one leaves some region impossible a few moves later. Place the 1–1 domino horizontally on row 1, column 3 and row 1, column 4.
  7. The “=” region at the top-right needs every pip to match (2 of its 4 cells are already filled) — 2 placements fit here for now, but every other one leaves some region impossible a few moves later. Place the 1–2 domino horizontally on row 2, column 2 and row 2, column 3.
  8. Row 2, column 4 has only one open neighbor, so its domino must run to row 3, column 4; the “=” region at the top-right needs every pip to match (3 of its 4 cells are already filled) — nothing else fits. Place the 1–3 domino vertically on row 2, column 4 and row 3, column 4.
  9. Row 3, column 1 has only one open neighbor, so its domino must run to row 2, column 1; the “=” region at the left needs every pip to match (3 of its 4 cells are already filled) — nothing else fits. Place the 0–2 domino vertically on row 2, column 1 and row 3, column 1.
  10. Row 4, column 4 has only one open neighbor, so its domino must run to row 5, column 4; the “=” region at the right needs every pip to match (1 of its 2 cells is already filled) — nothing else fits. Place the 0–3 domino vertically on row 4, column 4 and row 5, column 4.
  11. Row 6, column 4 has only one open neighbor, so its domino must run to row 7, column 4; the “=” region at the right needs every pip to match (1 of its 2 cells is already filled) — nothing else fits. Place the 0–4 domino vertically on row 6, column 4 and row 7, column 4.
  12. Row 1, column 1 has only one open neighbor, so its domino must run to row 1, column 2; the single-cell “<5” region at the top-left must total less than 5 — nothing else fits. Place the 4–5 domino horizontally on row 1, column 1 and row 1, column 2.
