Pips Answer for Wednesday, January 21, 2026

I started by looking at the Easy puzzle to get a feel for the day's logic. I noticed right away that the sum regions and the empty spots were the best places to start because they limit your options so much. For instance, a sum of 4 with only a couple of squares means you can only use specific domino sides. I moved on to the Medium grid where those equal regions really dictate the flow; I had to look at how the dominoes crossed over different zones to make sure the numbers matched up perfectly.

Finally, I tackled the Hard puzzle. This one was a real brain teaser because of the larger grid and the weird sum targets like zero. I found that placing the zeros first helped a lot because it narrowed down the possible neighbors. I basically worked from the most restrictive rules, like the 'less than 2' or 'greater than 4' spots, and then filled in the rest like a jigsaw puzzle until everything clicked into place according to the solution data.
