Answer for 2025-09-18

Solving this set of Pips puzzles felt like a fun mental workout. I started with Heidi Erwin's Easy puzzle, which was a great warm-up. The 'Sum 0' region at [1,2] and [1,3] was my first target—it’s the easiest way to narrow things down since both cells must be zeros.

Since [1,4] was also marked 'empty', that gave me a cluster of zeros to work with. I placed the [0,0] domino in a way that satisfied the sum constraints and then worked the 'Sum 6' region. Knowing that [1,1] was part of that sum helped me fit the [3,3] and [6,0] dominoes into place.

Answer for 2025-09-18

For the Medium puzzle, the 'Sum 20' across four cells ([1,1], [1,2], [2,1], [2,2]) was the anchor.

You can't reach 20 with small numbers, so I knew I had to use the high-value ends of the [6,2] and [5,4] dominoes there. The 'Equals' region for the three vertical cells [1,3], [2,3], and [3,3] acted as a bridge, forcing a specific orientation for the remaining pieces.

Answer for 2025-09-18

Finally, the Hard puzzle by Rodolfo Kurchan was a real brain-teaser. The 'Equals' region spanning five cells ([1,1] to [5,1]) is massive for a Pips board. I realized early on that if even one of those cells was determined, the whole column would follow.

I looked at the 'Sum 10' regions for [3,0]/[4,0] and [4,5]/[5,5]. To get a 10 with two cells, you basically need 5/5 or 6/4. By cross-referencing the available dominoes like [3,5] and [3,6], the logic eventually clicked into place. I used the 'Sum 0' at [5,0] as my final anchor to lock the last few dominoes in.

What I Learned

This puzzle set really highlighted how powerful 'empty' and 'zero' constraints are. In the Easy puzzle, they act as the foundation for the entire board. In the Medium puzzle, I learned to look for the highest possible sums first; a 'Sum 20' in just four cells is very restrictive and actually makes the puzzle easier because it eliminates so many low-value domino combinations.

The most interesting part of the Hard puzzle was the five-cell 'Equals' region. It taught me to look for 'global' constraints that affect multiple rows or columns simultaneously. It's not just about the individual dominoes, but how one value can ripple across the entire grid.

Frequently Asked Questions

What does an 'empty' region type mean in Pips?
An 'empty' region means that the cell contains zero pips. It’s essentially a 'Sum 0' constraint for a single square.
How do 'Equals' regions work when they cover more than two cells?
Every single cell within that designated region must have the exact same number of pips. If one is a 5, they all must be 5s.
What’s the best way to start a Hard Pips puzzle?
Look for the most extreme constraints. This usually means very large sums (like 10 in two cells) or very small sums (like 0 or 1). These narrow down your domino choices much faster than middle-of-the-road numbers.
Can I use the same domino twice?
No, each domino provided in the list for that specific puzzle level is unique and can only be used once to fill the board.
Does the orientation of the domino matter?
Yes! While the domino [3,0] is the same piece as [0,3], where you place the 3 and where you place the 0 is crucial for satisfying the regional math constraints.
