The errors in the REPL aren't the same as if you tried to compile it yourself. Using javac Game.java, I get the following error:

$ javac Game.java 
Game.java:15: error: cannot find symbol
        mHit += letter;
        ^
  symbol:   variable mHit
  location: class Game
1 error

Looks like a typo: mHit should be mHits.

No worries! Typos are a way of life. I only found it by executing the code and letting the compiler tell me the issue. If you're using an IDE for code development, they usually highlight symbols not defined, or defined and not used.

Thanks again Chris, I'm still using work spaces in the course.
