Backgammon

Phase 1: Board model, dice logic and rule foundation

Implement full board representation, checker distribution, dice rolling and basic movement rules.

• Represent points, bar, bear-off
• Validate legal moves
• Generate dice outcomes

Functional Output: A complete logical board with rule-checked movable pieces.

Phase 2: GUI foundation and interactive board rendering

Create an interface that correctly visualizes the board, checkers, dice and selectable moves.

• Render points + stacked pieces
• Display dice results
• Highlight legal moves

Functional Output: A functional GUI where pieces and legal moves appear interactively.

Phase 3: Human move execution and turn system

Link GUI actions to validated movement logic, including turn changes and multi-step moves.

• Drag/click to move
• Enforce all movement rules
• Update states across turns

Functional Output: Players can complete full turns with accurate rule enforcement.

Phase 4: AI opponent with random but valid decisions

Add a CPU player performing rule-compliant moves based on random selection among legal options.

• Generate legal AI moves
• Pick randomly
• Execute correctly

Functional Output: AI performs full valid turns without breaking game constraints.

Phase 5: Game flow, scoring, matches and persistence

Implement match structure, win detection, doubling cube logic (optional) and save/load support.

• Track game/match results
• Detect win states
• Store+restore sessions

Functional Output: Games and matches progress with persistent states and correct win evaluation.

Phase 6: Advanced features, undo/redo, hints and polish

Add usability and robustness enhancements, animations and extended logic checks.

• Provide legal move hints
• Implement undo/redo
• Refine visuals/feedback

Functional Output: A stable, polished backgammon app supporting hints, undo and smooth interactions.
