Clarifications

We cannot provide any information regarding release nor secret tests. Once your project has been graded, you can see a TA if you would like to find out why you failed a release or secret test.
The Random object parameter of the ClearCellGame constructor is a reference you will store as an instance variable of the ClearCellGame class. This object will be used while calling the getNonEmptyRandomBoardCell method of the BoardCell class. This is the only use you will have for this object (do not use it for anything else).
Additional information about the game clearing rules can be found at clearing rules. If you have any doubts about the clearing rules, please see us during office hours or in lecture.
