Hi there! Well these two isHit and isValidGuess are set to false to start with because otherwise we'd be assuming that whatever the user input is a valid guess and it is a hit. The isHit is going to keep track of whether or not we've guessed that letter already. The isValidGuess makes sure we're not putting in strange things as guesses like numbers, punctuation marks, and full strings. It's just making sure the letter is actually a letter.

Hope this helps! :sparkles:

that makes sense , thanks for clarifying things up ...

Thanks for your explanation. I have one more question, I am confused with the part while (!isValidGuess) I know ! means NOT, but look at the while loop, I don't get it. Please help!
