Designing the Tic-Tac-Toe

Get ready to dive into the design of a Tic-Tac-Toe game, a deceptively simple yet insightful case study for object-oriented design interviews. This exercise challenges you to think about game mechanics, player interactions, and extensibility beyond the classic 3x3 version. You’ll design a system that manages game states, enforces rules, and determines outcomes efficiently, all while applying solid OOP principles.

What You'll Practice:

• Translating straightforward game rules into a robust design.
• Applying clean abstractions for players, moves, and boards.
• Thinking about scalability from 3x3 to NxN boards.
• Using design patterns where appropriate for flexibility and clarity.
• Expressing your design through class diagrams and explaining your decisions.

By the end of this interview, you will be more confident in modeling game-like systems, reasoning about edge cases, and creating flexible designs that handle both current and future requirements.
