Step 5 · Triple Squeeze
Practice 1 of 3
Triple Squeeze: Three regions fit inside three rows or columns (or the reverse), so the rest of those lines is out.
Where to look: When nothing else works, pick a band of three rows or columns and list the regions that sit entirely inside it. If there are exactly three, you’ve found one. Bands along the edges are a good place to start.
