Pips July 29, 2026: Hints & Answers

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

Recap

The easy board requires strategic placement of 5 dominoes across 7 regions. The medium board involves 8 dominoes and 9 regions with various constraints. The hard board features 14 dominoes and 13 regions, demanding careful consideration of sum and empty constraints.

The three boards that day

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

Easy board · 5 dominoes · 7 regions

Dominoes: 2–23–02–56–24–3

  • two cells: exactly 4.
  • 2 ×one cell: left uncovered.
  • one cell: more than 1.
  • 2 ×two cells: all matching.
  • one cell: more than 5.

Small number of dominoes and regions makes it manageable.

Medium board · 8 dominoes · 9 regions

Dominoes: 4–45–06–35–13–25–51–10–0

  • 2 ×one cell: left uncovered.
  • 2 ×one cell: exactly 1.
  • three cells: exactly 1.
  • two cells: exactly 10.
  • three cells: exactly 12.
  • two cells: exactly 3.
  • two cells: exactly 9.

More dominoes and regions add complexity.

Hard board · 14 dominoes · 13 regions

Dominoes: 0–11–11–21–42–22–63–33–43–64–44–65–55–66–6

  • two cells: exactly 12.
  • three cells: exactly 11.
  • one cell: left uncovered.
  • three cells: exactly 3.
  • 3 ×two cells: exactly 3.
  • two cells: exactly 5.
  • two cells: exactly 8.
  • two cells: exactly 9.
  • two cells: exactly 10.
  • one cell: exactly 3.
  • four cells: exactly 24.

Large number of dominoes and complex constraints make it challenging.

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, 7 regions (2 empty, 2 equals, 2 greater, 1 sum)
    Medium board
    8 dominoes, 9 regions (7 sum, 2 empty)
    Hard board
    14 dominoes, 13 regions (12 sum, 1 empty)
  2. Hint 2: Easy board: how to approach it

    Method only.

    Start by identifying regions with limited possibilities, such as those with sum or equals constraints.

  3. Hint 3: Easy board: where to start

    One region named by its constraint.

    Begin with the region that has a sum constraint over 2 cells.

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

    The same two steps, one difficulty up.

    Focus on regions with specific sum constraints to limit domino placement options.

    Start with a region that has an empty constraint over 1 cell.

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

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

    Look for regions with high sum constraints to narrow down domino options.

  6. Hint 6: Hard board: where to start

    The last rung before the full walkthroughs.

    Begin with a region that has a sum constraint over 2 cells.

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 2/2 domino, then the 4/3 domino in a way that satisfies the sum constraint. Next, place the 6/2 domino, followed by the 3/0 domino. Finally, place the 2/5 domino, ensuring all regions meet their constraints.

  • Medium board · 8 dominoes

    Medium board walkthrough

    Begin by placing the 0/0 domino. Then, place the 1/1 domino in a region with a sum 1 constraint. Continue with the 4/4 domino, followed by the 5/0 and 3/2 dominoes, ensuring that the sum constraints are met. Place the 5/5 domino, then the 5/1 domino. Finally, place the 6/3 domino, satisfying all region constraints.

  • Hard board · 14 dominoes

    Hard board walkthrough

    Start by placing the 6/6 domino. Then, place the 5/5 and 4/4 dominoes in regions with sum constraints. Continue with the 3/3 domino, followed by the 2/2 domino. Place the 1/1 and 0/1 dominoes in regions with low sum constraints. Next, place the 1/2, 1/4 dominoes, ensuring that the sum constraints are met. Place the 2/6 domino, then the 3/4 and 3/6 dominoes. Continue with the 4/6 and 5/6 dominoes, satisfying all region constraints. Finally, place the remaining dominoes, ensuring all regions meet their constraints.
