Encapsulation

Each game will have its specific way of making a move. Hence, the makeMove() function will be unique to each game.

Abstraction

The TicTacToe and Sudoku classes are able to use the public attributes and methods of the Game class.

Inheritance

Only interested in the makeMove() method, which simply performs the move and doesn’t go into the depth of how the move is being made.

Polymorphism

The method getPlayers(), getIsHuman(), and setValue() are examples of this principle.
