The scope felt manageable at first but the win detection logic is where I started second-guessing myself.
Start by clarifying requirements and choosing a simple tech stack (e.g., React Native or Flutter) that allows rapid development. Then outline a minimal architecture: state for board, current player, and game status; pure functions for win/draw detection; and a simple UI with grid, status, and reset. Implement incrementally, testing core logic first, then wiring up the UI.
Pro tip: Focus on clean separation between game logic and UI, and use immutable state updates to avoid bugs. Verbally explain your trade-offs (e.g., using a simple array vs. a more complex data structure) to demonstrate engineering maturity.
Confirm requirements: 3x3 grid, two local players, win/draw detection, move prevention after game ends, status display, reset button. Ask about platform preference (iOS/Android/cross-platform) and any constraints.
Select a framework (e.g., React Native, Flutter, or native) based on speed and familiarity. Outline a simple architecture: state management (e.g., useState or Provider), pure functions for game logic, and presentational components.
Write functions to check win conditions (rows, columns, diagonals) and draw (board full). Manage state for board (array of 9), current player, and game status (playing, won, draw). Ensure moves are blocked after game over.
Create a 3x3 grid of touchable cells, a status text showing current player or result, and a reset button. Connect UI to state and logic, ensuring moves update the board and status.
Manually test win, draw, and move prevention scenarios. Fix any bugs and ensure reset works. If time permits, add simple styling for clarity.
