Answer for 2025-10-21

I started by looking at the Easy grid, which is small but has some tight constraints. The sum target of 8 in the top left and 16 in the top row immediately limited my choices.

I knew that with pips, you have to match the dominoes provided to the board space, so I focused on placing the [6,6] and [4,5] dominoes where they could actually fit the math. Once I saw that the sum of 16 had to use high numbers, it fell into place. Moving to the

Answer for 2025-10-21

Medium puzzle, the sum of 21 across four cells was the big giveaway; that requires very high values from the domino set. I used the equals constraint on cells [1,4], [2,4], and [3,4] to anchor the right side. The hardest part was the 8x8 grid. I looked for the sum targets of 0 and 1 first because they are very restrictive.

A sum of 0 in three cells [2,4], [2,5], [3,5] means all those cells must be 0 pips. This narrowed down which dominoes could even be in that area. I then tackled the sum of 18 in the bottom left, which again forces high numbers like 6s. By cross-referencing the available domino list with these fixed points, I could deduce the orientation of each pair. I carefully checked the 'unequal' region in the middle to make sure no numbers repeated there, which helped me slot in the final few pieces like the [2,2] and [1,1] dominoes.

💡

What I Learned

I noticed a really interesting pattern in the Hard puzzle where the small sum targets (0, 1, and 3) were clustered near the center, while the larger targets (12, 18, and 9) were on the outer edges. This usually means the puzzle is designed to be solved from the outside in, or by using the zeros as anchors.

I also learned that the 'equals' constraint over three cells is much more powerful than it looks because it forces you to use dominoes that share the same pip value or find three matching ends, which is rare in a standard set. A tricky move was managing the [6,6] domino in the Easy puzzle; if you place it too early without checking the sum regions, you can easily block yourself from reaching a target of 16.

Frequently Asked Questions

What is the best way to start a Pips puzzle?
Always look for the most restrictive regions first. This means very small sums (like 0 or 1), very large sums (like 18), or 'equals' constraints involving three or more cells.
Can dominoes be flipped in this game?
Yes, dominoes can be placed horizontally or vertically, and either end can go in either cell of the pair, as long as they fit the grid's math rules.
What does the 'empty' region mean?
An empty region usually means that specific cell doesn't have a mathematical constraint like a sum or inequality, but it still must be filled by a part of a domino.
How do you handle the 'unequal' constraint?
This rule means that every cell within that highlighted region must contain a different number of pips. It is very similar to Sudoku rules.
