Easy Pips answer — August 22, 2025

5 dominoes · 5×3 board · by Heidi Erwin

Hint 1: where to start

Start with the 8 region at the right: the only way to make it with these dominoes is 3 + 5.

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

6 dominoes · 4×4 board · by Heidi Erwin

Hint 1: where to start

Start with the “=” region at the center: all 3 cells must show the same number, and only 5s appear on enough dominoes to fill it.

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