Implement Game Scoring for Memory Matching Game

This checklist provides step-by-step instructions for implementing scoring mechanics using HTML, CSS, and JavaScript.

HTML Structure

• Create a score display container in your HTML
• Add elements for current score, moves counter, and timer
• Include elements for best score/high score display
• Add game statistics section (matches found, total pairs, etc.)

<div class="score-container">
  <div class="current-score">Score: <span id="score">0</span></div>
  <div class="moves-counter">Moves: <span id="moves">0</span></div>
  <div class="timer">Time: <span id="timer">00:00</span></div>
  <div class="best-score">Best Score: <span id="best-score">--</span></div>
</div>

CSS Styling

• Style the score container with appropriate positioning
• Create visual feedback for score changes (animations/transitions)
• Design different states for score display (normal, bonus, penalty)
• Add responsive design for score elements
• Style game completion celebration elements

JavaScript Scoring Logic

Core Variables Setup

• Initialize score tracking variables (currentScore, moves, startTime)
• Set up scoring rules constants (matchPoints, timeBonuses, penalties)
• Create variables for game statistics tracking

Scoring Mechanics Implementation

• Match Scoring: Award points for successful card matches

  • Base points per match (e.g., 100 points)
  • Consecutive match bonuses
  • Time-based bonus calculations

• Move Counter: Track and display number of moves/attempts

  • Increment on each card flip pair
  • Calculate efficiency scoring based on moves

• Timer Implementation:

  • Start timer when first card is flipped
  • Calculate time-based scoring bonuses
  • Display formatted time (MM:SS)

• Penalty System (optional):

  • Deduct points for incorrect matches
  • Time penalties for slow gameplay

Score Calculation Functions

• Create updateScore() function for match successes
• Implement calculateTimeBonus() for completion bonuses
• Add calculateFinalScore() combining all factors
• Create displayScore() function with animations

Local Storage Integration

• Save current game score to localStorage
• Implement high score tracking and persistence
• Create functions to retrieve and display best scores
• Add score history functionality

Game Events Integration

• Connect scoring to card matching events
• Update score display on successful matches
• Trigger score animations and feedback
• Handle game completion scoring summary

Score Display Features

• Real-time score updates during gameplay
• Animated score changes (+points animations)
• Game completion score summary modal
• Leaderboard or score comparison features

Testing Checklist

• Test scoring accuracy with different match scenarios
• Verify timer functionality and time-based bonuses
• Test localStorage persistence across browser sessions
• Validate responsive design on different screen sizes
• Test edge cases (rapid clicking, game resets)

Enhancement Ideas

• Add difficulty-based scoring multipliers
• Implement streak bonuses for consecutive matches
• Create scoring achievements/badges system
• Add sound effects for score changes
• Implement score sharing functionality

Acceptance Criteria

• Score increases correctly on successful matches
• Move counter accurately tracks player attempts
• Timer functions properly from game start to finish
• High scores are saved and displayed correctly
• Score display is visually appealing and responsive
• Game completion shows comprehensive score breakdown
