No. Any straight run of letters that spells a listed word counts, even if the same letters also appear somewhere else in the grid.
The game checks the letters you trace, not a fixed spot, so a second copy of a word is as good as the first.
What counts
- A straight selection whose letters spell a listed word, forwards or backwards (all eight directions).
- A word you have already found does not count a second time.
With only eight words to find, a chance repeat is rare but harmless. For more, read the Word Search tips and strategy.
