+# Scoring System - Neural Nexus
+
+## Overview
+
+The Neural Nexus scoring system is designed to reward both speed and accuracy while providing clear progression feedback to players. The system balances immediate gratification with long-term engagement.
+
+## Core Scoring Components
+
+### 1. Base Level Score
+**Formula:** `100 points × level number`
+
+**Rationale:**
+- Provides increasing rewards for higher levels
+- Simple calculation that players can understand
+- Scales with difficulty progression
+- Encourages continued play to reach higher levels
+
+**Examples:**
+- Level 1 completion: 100 points
+- Level 5 completion: 500 points  
+- Level 10 completion: 1,000 points
+- Level 25 completion: 2,500 points
+
+### 2. Time Bonus
+**Formula:** `10 points × seconds remaining`
+
+**Rationale:**
+- Rewards efficient play without penalizing thoughtful players
+- Creates tension between speed and accuracy
+- Provides variable reward based on performance
+- Encourages replay to improve times
+
+**Implementation:**
+```javascript
+function calculateTimeBonus(timeLeft) {
+  return timeLeft * 10;
+}
+
+// Example: Complete level with 15 seconds remaining = 150 bonus points
+```
+
+**Time Allocation by Level:**
+- Levels 1-3: 60 seconds (generous learning time)
+- Levels 4-6: 58 seconds (slight pressure)
+- Levels 7-9: 56 seconds (building urgency)
+- Levels 10+: Decreasing by 2 seconds every 3 levels (minimum 45 seconds)
+
+### 3. Accuracy Multiplier (Future Feature)
+**Planned Formula:** `1.0x - 2.0x based on mistakes`
+
+**Design Concept:**
+- Perfect completion (no invalid connections): 2.0x multiplier
+- 1-2 mistakes: 1.5x multiplier
+- 3-4 mistakes: 1.2x multiplier
+- 5+ mistakes: 1.0x multiplier (base score)
+
+## Scoring Psychology
+
+### Immediate Feedback
+**Visual Score Updates:**
+- Points appear immediately upon level completion
+- Animated number counting creates satisfaction
+- Color coding indicates performance level
+- Sound effects reinforce positive achievements
+
+**Score Breakdown Display:**
+```
+Level Complete!
+Base Score: 500 points (Level 5)
+Time Bonus: 180 points (18 seconds)
+Total: 680 points
+```
+
+### Progress Indicators
+**Cumulative Score Tracking:**
+- Total score displayed prominently during gameplay
+- Score history maintained in local storage (future)
+- Personal best tracking for each level (future)
+- Global leaderboards consideration (far future)
+
+## Technical Implementation
+
+### Score Calculation Function
+```javascript
+function calculateLevelScore(level, timeLeft, mistakes = 0) {
+  const baseScore = 100 * level;
+  const timeBonus = timeLeft * 10;
+  const accuracyMultiplier = calculateAccuracyMultiplier(mistakes);
+  
+  const totalScore = Math.floor((baseScore + timeBonus) * accuracyMultiplier);
+  
+  return {
+    baseScore,
+    timeBonus,
+    accuracyMultiplier,
+    totalScore
+  };
+}
+```
+
+### Score Update Animation
+```javascript
+function animateScoreUpdate(newScore, oldScore) {
+  const scoreDifference = newScore - oldScore;
+  const duration = 1000; // 1 second
+  const startTime = Date.now();
+  
+  function updateDisplay() {
+    const elapsed = Date.now() - startTime;
+    const progress = Math.min(elapsed / duration, 1);
+    
+    // Ease-out animation curve
+    const easedProgress = 1 - Math.pow(1 - progress, 3);
+    const currentScore = Math.floor(oldScore + (scoreDifference * easedProgress));
+    
+    document.getElementById('score').textContent = currentScore;
+    
+    if (progress < 1) {
+      requestAnimationFrame(updateDisplay);
+    }
+  }
+  
+  updateDisplay();
+}
+```
+
+## Balancing Considerations
+
+### Preventing Score Inflation
+**Design Safeguards:**
+- Time limits prevent excessive farming
+- Increasing difficulty maintains challenge
+- Score scaling ensures later levels are more rewarding
+- No score for incomplete levels
+
+### Encouraging Healthy Play Patterns
+**Positive Behaviors Rewarded:**
+- Completing levels efficiently (time bonus)
+- Progressing to harder content (base score scaling)
+- Maintaining accuracy (future multiplier system)
+
+**Avoiding Negative Patterns:**
+- No penalty for taking time to think
+- No score reduction for failed attempts
+- Restart without penalty encourages experimentation
+
+## Future Enhancements
+
+### Achievement Integration
+**Score-Based Achievements:**
+- "High Scorer": Reach 10,000 total points
+- "Speed Demon": Earn 500+ time bonus in single level
+- "Perfectionist": Complete 10 levels with perfect accuracy
+- "Marathon Runner": Reach level 50
+
+### Daily Challenges
+**Special Scoring Modes:**
+- Speed run mode: Maximum time bonus
+- Accuracy mode: Perfect connections required
+- Endurance mode: Consecutive level completion
+- Efficiency mode: Minimum connection path scoring
+
+### Leaderboards
+**Competition Features:**
+- Daily high scores
+- Weekly challenges
+- Global rankings
+- Friend comparisons
