Add private property to class: + ```typescript + private previousScore: number = 0; + ``` + + 2. Add restart() public method: + ```typescript + restart(): void { + // Store current score as previous score BEFORE reset + this.previousScore = this.score; + + // Reset grid to initial state + this.gridManager.initializeGrid(); + + // Reset score to 0 for new game + this.score = 0; + + // Reset state machine to IDLE + this.gameStateManager.reset(); + + // Hide game over overlay + this.hideGameOverOverlay(); + + // Update score displays (current = 0, previous = preserved) + this.updateScoreDisplay(); + this.updatePreviousScoreDisplay(); + + // Emit restart event for extensibility (future listeners can subscribe) + this.events.emit('game:restart', undefined as never); + } + ``` + + 3. Add hideGameOverOverlay() private method: + - Get overlay element by ID: 'game-over-overlay' + - Set overlay.style.display = 'none' + + 4. Add updatePreviousScoreDisplay() private method: + - Get previous-score-display element by ID + - Set text to `Previous: ${this.previousScore}` + - Set display to 'block' to show it (if currently hidden) + - If previousScore is 0, hide the element + + 5. Update GameEvents interface in src/types/index.ts: + - Add 'game:restart': void event type + + Follow existing Game.ts patterns: public methods for game control, private methods for UI manipulation, emit events for state changes. + + + npm test -- --run --reporter=verbose Game + + + restart() method implemented in Game.ts, stores previousScore before reset, resets grid/score/state/UI, updates both displays, emits game:restart event for extensibility, tests passing. + + + + + Task 3: Wire up restart button click handler + src/game/Game.ts + + - Test 1: Restart button click handler calls game.restart() + - Test 2: Click handler is registered in constructor + - Test 3: Restart button element is found by ID + + + Update src/game/Game.ts constructor: + + 1.

Note the current score displayed + 5. Click "Play Again" button + 6. Verify: + - Overlay disappears immediately + - Grid is reset with all tiles visible + - Score display shows "Score: 0" (new game) + - Previous score display shows "Previous: X" (where X was your final score) + - You can select and match tiles again (game is playable) + 7.
