Easy Pips answer — September 11, 2025

5 dominoes · 6×5 board · by Rodolfo Kurchan

Hint 1: where to start

Start with the “=” region at the top: all 3 cells must show the same number, and only 1s appear on enough dominoes to fill it.

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

7 dominoes · 5×6 board · by Rodolfo Kurchan

  • the single-cell 5 region at the bottom-right: 5
Hint 3: step-by-step solution

  4. The 14 region at the top needs a total of exactly 14 — 2 placements fit here for now, but every other one leaves some region impossible a few moves later. Place the 3–4 domino horizontally on row 1, column 1 and row 1, column 2.
  5. Row 1, column 3 has only one open neighbor, so its domino must run to row 1, column 4; the 14 region at the top needs a total of exactly 14 (1 of its 3 cells is already filled) — nothing else fits. Place the 5–5 domino horizontally on row 1, column 3 and row 1, column 4.
  6. Row 3, column 2 has only one open neighbor, so its domino must run to row 2, column 2; the 9 region at the left needs a total of exactly 9 (1 of its 2 cells is already filled) — nothing else fits. Place the 4–4 domino vertically on row 2, column 2 and row 3, column 2.
