The solver started with the high-efficiency word SALET. This provided excellent feedback, confirming the presence of S, A, and L, and hinting at the placement of the first two letters.

The second guess, SATIS, was used to narrow down the remaining candidates. While it confirmed the initial letters, it also revealed the structure of the word by testing the position of the remaining vowels and consonants.

Finally, the correct word SATIN was identified and confirmed, completing the puzzle in just three rounds.
