Pips October 31, 2026: Hints & Answers

Constructed by Ian Livengood, Rodolfo Kurchan, Rodolfo Kurchan, edited by Ian Livengood.

Recap

The easy board requires strategic placement of 5 dominoes across 6 regions with basic constraints. The medium board involves 7 dominoes and 7 regions with more complex constraints. The hard board features 14 dominoes and 16 regions with a wide variety of challenging constraints.

The three boards that day

The tray and each region's rule — board data, no solutions.

Easy board · 5 dominoes · 6 regions

Dominoes: 2–63–23–51–63–6

  • two cells: exactly 12.
  • three cells: all matching.
  • one cell: exactly 2.
  • one cell: under 3.
  • two cells: more than 5.
  • one cell: more than 5.

This board is relatively straightforward due to the small number of dominoes and restrictive constraints.

Medium board · 7 dominoes · 7 regions

Dominoes: 2–62–05–42–31–04–32–2

  • three cells: all different.
  • two cells: more than 3.
  • three cells: all matching.
  • one cell: more than 4.
  • two cells: exactly 5.
  • one cell: exactly 6.
  • two cells: more than 5.

This board requires more strategic thinking due to the increased number of dominoes and constraints.

Hard board · 14 dominoes · 16 regions

Dominoes: 5–54–45–21–42–00–01–32–33–64–61–24–53–42–2

  • two cells: exactly 3.
  • two cells: exactly 5.
  • 3 ×one cell: left uncovered.
  • two cells: exactly 0.
  • two cells: all different.
  • 2 ×one cell: exactly 3.
  • four cells: all matching.
  • two cells: more than 8.
  • one cell: more than 4.
  • two cells: exactly 7.
  • one cell: exactly 1.
  • two cells: all matching.
  • three cells: exactly 3.

This board is challenging due to the large number of dominoes and complex constraints.

Pips hints, one rung at a time

Six rungs, easy board first. The recap above already named the walkthroughs, so this ladder is here for anyone replaying the boards fresh rather than as a spoiler shield.

  1. Hint 1: How the three boards compared

    Sizes and constraint mixes, counted off the boards.

    Easy board
    5 dominoes, 6 regions (2 greater, 2 sum, 1 equals, 1 less)
    Medium board
    7 dominoes, 7 regions (3 greater, 2 sum, 1 equals, 1 unequal)
    Hard board
    14 dominoes, 16 regions (8 sum, 3 empty, 2 equals, 2 greater, 1 unequal)
  2. Hint 2: Easy board: how to approach it

    Method only.

    Start by identifying regions with the most restrictive constraints, such as the sum 2 over 1 cell or less 3 over 1 cell, to narrow down domino placement options.

  3. Hint 3: Easy board: where to start

    One region named by its constraint.

    Begin with the region that requires a sum of 2 over 1 cell, as it has the fewest possible domino combinations.

  4. Hint 4: Medium board: approach and first region

    The same two steps, one difficulty up.

    Focus on regions with specific numerical constraints, such as sum 6 over 1 cell or greater 4 over 1 cell, to start placing dominoes.

    Start with the region that requires a sum of 6 over 1 cell, as it has limited domino options.

  5. Hint 5: Hard board: how to approach it

    Where the hard board differed in kind, not just size.

    Begin by identifying and focusing on regions with the most restrictive or unique constraints, such as the empty over 1 cell or sum 0 over 2 cells.

  6. Hint 6: Hard board: where to start

    The last rung before the full walkthroughs.

    Start with a region that has a unique constraint, such as requiring an empty cell or a specific small sum.

Every Pips walkthrough from that day

All three walkthroughs, folded: each one places every domino on its board, one after another.

  • Easy board · 5 dominoes

    Easy board walkthrough

    Place the 1/6 domino in the sum 2 over 1 cell region. Then, use the equals over 3 cells constraint to place the 3/6 domino. Next, place the 2/6 domino in the greater 5 over 2 cells region. The 3/5 domino fits in the remaining region with a sum of 12 over 2 cells. Finally, place the 3/2 domino.

  • Medium board · 7 dominoes

    Medium board walkthrough

    Place the 2/0 domino in the sum 6 over 1 cell region. Use the greater 3 over 2 cells constraint to place the 4/3 domino. Then, place the 2/3 domino in the unequal over 3 cells region. The 5/4 domino fits in the sum 5 over 2 cells region. Next, place the 2/2 domino. Finally, use the equals over 3 cells constraint to place the remaining dominoes.

  • Hard board · 14 dominoes

    Hard board walkthrough

    Begin by placing dominoes in regions with the most restrictive constraints. Place the 0/0 domino in the sum 0 over 2 cells region. Use the sum 3 over 2 cells constraint to place the 1/2 domino. Then, place the 2/0 domino in the empty over 1 cell region. Continue placing dominoes in regions with specific constraints, such as the greater 8 over 2 cells region with the 5/5 and 4/4 dominoes. Use the equals over 4 cells constraint to place several dominoes. The 3/6 and 4/6 dominoes fit in regions requiring larger numbers. As the board progresses, use the sum 7 over 2 cells and sum 5 over 2 cells constraints to place the remaining dominoes. Finally, fill in the remaining regions with the leftover dominoes, ensuring all constraints are satisfied.
