Why the bonus word matters
In most Text Twist rounds you can only advance by finding at least one word that uses every letter you were given. These are the bonus words, and they are often the hardest to spot under time pressure. The solver highlights them with a star and places them in their own length group at the top of the results, so the word you actually need is impossible to miss.
Some rounds have more than one full-length word. The solver lists all of them, giving you a choice and a safety net if one does not register. Once you clear the bonus, you can go back and fill in the shorter words to boost your score.
