NYT Pips easy answer for 2025-09-21

Complete answer for 2025-09-21 (Easy)

Solving the Pips puzzles for September 21st felt like a fun morning challenge. I always start with the Easy one to warm up my brain.

I noticed right away that one region needed a sum of 0, which is basically a gift because it has to be the [0,0] domino. Once I placed that, the rest of the small grid fell into place by looking at the target sums of 5 and 6.

Complete answer for 2025-09-21 (Medium)

For the Medium puzzle, I had to change gears. There was a huge region with a target sum of 42.

I knew I had to pack that area with the heavy hitters, like the dominoes starting with 6. I spent a good chunk of time making sure I didn't use a domino that was needed for one of the 'less than' constraints elsewhere. The

Complete answer for 2025-09-21 (Hard)

Hard puzzle was definitely the main event. It had an 'unequal' region which always makes me pause. I started by looking at the sum of 18 and the sum of 10.

For the sum of 10, the [5,5] domino was the perfect fit. Then I tackled the sum of 18 by combining high-value pips. The hardest part was making sure the 'unequal' region didn't have any repeating numbers, which took a little bit of trial and error with the [3,6] and [4,5] dominoes. I just kept checking which dominoes were left on my list and crossing them off as I found their homes.

What I Learned

One thing that really clicked for me today is how important the big sum regions are in the Medium and Hard puzzles. They act like anchors for the high-value dominoes.

I also learned that if I get stuck on an 'unequal' region, it usually helps to look at the 'equals' or specific sum regions right next to it because they limit the pool of available numbers. I noticed a pattern where the [0,0] domino is almost always placed near the edges or in those tiny zero-sum regions, which makes sense for the puzzle design. Today's puzzles also reminded me to always double-check the 'less than' constraints last, as they are usually flexible enough to accommodate whatever dominoes you have left over at the end.

Frequently Asked Questions

What is the best way to start a Pips puzzle?

I always look for the regions with a sum of 0 or the very small target sums first. These usually only have one or two possible dominoes that can fit, which gives you a great starting point for the rest of the grid.

How do I handle the 'unequal' regions in the Hard puzzle?

Think of it like a Sudoku block. You just have to make sure no two pips in that specific highlighted area are the same number. I usually leave these for the middle of my solve after I have placed a few dominoes nearby to see what numbers are even available.

What should I do if I run out of dominoes before the grid is full?

This usually means a domino was placed in the wrong spot earlier. I go back to the biggest sum region and see if I accidentally used a low-value domino there that should have been used in a 'less than' spot instead.

Are the dominoes always used only once?

Yes, just like a real set of dominoes, you can only use each specific pair of pips one time in the entire puzzle. If you think you need two [6,6] dominoes, one of them is definitely in the wrong place!
