Machine Coding Tic Tac Toe - LLD Case Study

A machine-coding case study

This case study walks through the low-level design of a tic-tac-toe game that is built as a machine-coding exercise. The aim is to design and implement a full game from scratch, applying object-oriented principles, data structures and algorithms along the way.

What you practise

The exercise is a good way to practise deciding which classes a game needs, how state is held, and how win conditions are checked. Those are the decisions a machine-coding round tests, and a small game gives you room to make them without the pressure of a large system.

Level

The description pitches the material at beginners, while the listed level is advanced. Read the outline before starting, and treat it as a worked design problem rather than a first lesson in object-oriented programming.
