I'm trying out the game, the first thing it asks me is "Enter Box: " could be a little more descriptive, enter ponies into the box named? Index, horizontally or vertically placed? However I can guess It's mark position layed horizontal.
You may want to print each time beforehand, rather than display as a result:
123
456
789
Also in "playGame()", consider how many turns are possible for one person and "getMove()" so a loop.
