# Tic Tac Toe notes

## Checkpoint 1 Notes

Which class is responsible for each of the following behaviors?
For each, explain how the behavior is accomplished.

### Checking to see whether the game is over
TTTGame checks whether the board is full and which player (if any)
wins. If a player meets a win condition (yet to be defined) or
if all spaces are full and no additional moves are possible, the
end of the game is (or should be) triggered in is_over()

### Determining which actions are available at a particular state
TTTGame generates the list of available actions based on the current state

### Showing the board
TTTView controls generating the board and printing it to the screen through
the print_board() and get_action() methods

### Choosing which action to play on a turn
TTTHumanPlayer allows the user to play an action based on the list of
available actions generated
