The game board is a well ordered grid, I can't fathom why you'd not organise it into an array. The cell object has 3 completely redundant fields. Most of the code just checks the mined parameter of cell objects, but for some reason there is also an isMined function. The code placing mines uses its own data structure to keep track of where mines have been placed, rather than the board data, and manages to be O(n^2) instead of O(n) because of that choice. Overall it is code that takes a lot of unnecessary detours.
