Crossclimb #718 Answer – April 18, 2026
SINEWAVE
Answer
SINEWAVE
Combo Clue
“A two-word phrase for the graph of a mathematical function that goes up and down”
📖 How I Solved It
I had a bit of a rollercoaster with puzzle #718, especially with the clue for the combo answer. The clue said it was a two-word phrase for the graph of a mathematical function that goes up and down, and I was stuck for a while. I kept thinking about sine curves and waves but couldn't quite piece it together. I even guessed 'UPDOWN' at one point, which was definitely not it! After some back and forth, I finally landed on 'SINEWAVE' after realizing how it perfectly fit the clue. The word ladder was a fun challenge too, especially moving from 'SINE' to 'FINE'. I almost tripped myself up guessing 'FIND' instead, thinking it was a dead end, but it led me right to 'WIND'. Overall, it felt great to crack it after a bit of head-scratching.
