Easy Pips answer — October 23, 2025
6 dominoes · 4×4 board · by Rodolfo Kurchan
Hint 1: where to start
Start with the “<1” region at the center: the only way to make it with these dominoes is 0 + 0 + 0.
Hint 2: the pips in each region
- the “=” region at the top-right: 3, 3, 3
- the 3 region at the left: 1, 1, 1
- the “<1” region at the center: 0, 0, 0
- the single-cell “<5” region at the bottom: 4
Hint 3: step-by-step solution
- The “<1” region at the center must total less than 1 — 3 placements fit here for now, but every other one leaves some region impossible a few moves later. Place the 0–3 domino vertically on row 2, column 4 and row 3, column 4.
- The 3 region at the left needs a total of exactly 3 — nothing else fits. Place the 1–1 domino vertically on row 2, column 1 and row 3, column 1.
- The 3 region at the left needs a total of exactly 3 (2 of its 3 cells are already filled) — nothing else fits. Place the 1–4 domino vertically on row 1, column 2 and row 2, column 2.
- Row 1, column 3 has only one open neighbor, so its domino must run to row 2, column 3; the “=” region at the top-right needs every pip to match (1 of its 3 cells is already filled) — nothing else fits. Place the 3–3 domino vertically on row 1, column 3 and row 2, column 3.
- The “<1” region at the center must total less than 1 (1 of its 3 cells is already filled) — nothing else fits. Place the 0–4 domino vertically on row 3, column 2 and row 4, column 2.
- Row 3, column 3 has only one open neighbor, so its domino must run to row 4, column 3; the “<1” region at the center must total less than 1 (2 of its 3 cells are already filled) — nothing else fits. Place the 0–5 domino vertically on row 3, column 3 and row 4, column 3.
