, 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
.

Courses Plus Student 3,405 PointsThanks Chris! man do I suck at this...

Treehouse Moderator 68,457 PointsNo 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.
