+# UNIFIED_API.md Update Recommendations
+
+This document outlines the changes needed in `/vimazing/games/UNIFIED_API.md` to reflect the scoring refactor implemented in vim-maze v2.3.0.
+
+## Summary of Changes
+
+Vim-maze has implemented a new pattern for score management:
+- **ScoreManager** is now a pure data collector (no score calculation)
+- **Score calculation** moved to consumer (via utility function or custom logic)
+- **Game-over conditions** are fully flexible and consumer-controlled
+
+## Required Updates
+
+### 1. Example Entry Point (Line ~100)
+
+**OLD:**
+```typescript
+// vim-maze
+useGame({ rows: 24, cols: 32, timeLimit: 600 })
+```
+
+**NEW:**
+```typescript
+// vim-maze (with custom game-over condition)
+useGame({ 
+  rows: 24, 
+  cols: 32, 
+  gameOver: (sm) => sm.timeValue >= 600000  // 10 minutes in milliseconds
+})
+```
+
+### 2. Score Manager Type (Line ~189-201)
+
+**OLD:**
+```typescript
+type ScoreManager = {
+  // Required Timing
+  timeValue: number;            // Current time in milliseconds
+  
+  // Required Metrics
+  totalKeystrokes: number;      // Total keys pressed
+  
+  // Required Result
+  finalScore: number | null;    // 0-1000 (null until game-won)
+  
+  // Optional: Game-specific metrics
+  // [additional fields as needed]
+};
+```
+
+**NEW:**
+```typescript
+type ScoreManager = {
+  // Required Timing
+  timeValue: number;            // Current time in milliseconds
+  
+  // Required Metrics
+  totalKeystrokes: number;      // Total keys pressed
+  
+  // Optional: Game-specific metrics
+  // [additional fields as needed]
+  // NOTE: finalScore removed - calculation moved to consumer
+};
+```
+
+**Add note:**
+```
+**Important:** ScoreManager is now a pure data collector. 
+Score calculation has been moved to the consumer. 
+Games should provide a utility function like `calculateScore()` 
+or instructions for score calculation in their documentation.
+```
+
+### 3. GameOptions Examples (Line ~222-230)
+
+**OLD:**
+```typescript
+// vim-maze
+type GameOptions = {
+  rows: number;
+  cols: number;
+  timeLimit?: number;
+};
+```
+
+**NEW:**
+```typescript
+// vim-maze
+type GameOptions = {
+  rows: number;
+  cols: number;
+  gameOver?: boolean | ((scoreManager: ScoreManager) => boolean);
+};
+```
+
+### 4. Scoring Implementation Section (Line ~257-265)
+
+**OLD:**
+```typescript
+**vim-maze approach:**
+```typescript
+// Size-based: time + keystrokes × maze size
+const baseScore = 1000 - timePenalty - keystrokePenalty;
+const sizeMultiplier = max(1.0, (rows × cols) / 500);
+const finalScore = min(1000, baseScore × sizeMultiplier);
+```
+```
+
+**NEW:**
+```typescript
+**vim-maze approach (v2.3+):**
+```typescript
+// Pure data collection in ScoreManager
+const scoreManager = useScore({ /* dependencies */ });
+// scoreManager returns: { timeValue, keystrokes, optimalSteps, efficiency, ... }
+
+// Score calculation moved to consumer
+import { calculateMazeScore } from '@vimazing/vim-maze';
+const finalScore = calculateMazeScore(scoreManager, mazeSize);
+// Base: 1000 - (time/10) - (keystrokes/2)
+// Then: multiply by size factor = max(1.0, (rows × cols) / 500)
+// Final: clamp to 0-1000
+```
+```
+
+### 5. Scoring Requirements Section (Line ~203-208)
+
+**OLD:**
+```
+**Scoring Requirements:**
+- Score range: 0-1000 (capped)
+- Score calculated on game-won
+- Based on time and keystrokes (minimum)
+- Can include game-specific penalties/bonuses
+```
+
+**NEW:**
+```
+**Scoring Requirements:**
+- Score range: 0-1000 (capped)
+- Based on time and keystrokes (minimum)
+- Can include game-specific penalties/bonuses
+- **NEW:** Score calculation moved to consumer via utility function
+- Games should provide `calculateScore()` or similar utility
+- Games should document their scoring formula clearly
+```
+
+### 6. Game-Over Conditions Pattern (New Section)
+
+Add a new subsection after "Scoring Requirements":
+
+```markdown
+### Game-Over Conditions
+
+Starting with vim-maze v2.3+, games have full control over game-over conditions:
+
+```typescript
+type GameOptions = {
+  // ...game-specific options...
+  gameOver?: boolean | ((scoreManager: ScoreManager) => boolean);
+};
+```
+
+**Examples:**
+```typescript
+// Static game-over
+useGame({ rows: 24, cols: 32, gameOver: true })
+
+// Time-based
+useGame({ 
+  rows: 24, 
+  cols: 32,
+  gameOver: (sm) => sm.timeValue >= 600000  // 10 minutes
+})
+
+// Efficiency-based
+useGame({
+  rows: 24,
+  cols: 32,
+  gameOver: (sm) => sm.efficiency > 150  // >150% keystrokes
+})
+
+// Combined conditions
+useGame({
+  rows: 24,
+  cols: 32,
+  gameOver: (sm) => sm.efficiency > 150 || sm.timeValue >= 600000
+})
+```
+
+**Benefits:**
+- No hardcoded game-over logic in libraries
+- Consumers define win/loss conditions
+- Flexible for tournaments, variations, custom rules
+```
+
+### 7. Hook Specifications - useScore Section (Line ~424+)
+
+Find and update the useScore section:
+
+**OLD:**
+```typescript
+export function useScore(/* dependencies */) {
+  // ...
+  const [timeValue, setTimeValue] = useState(0);
+  const [finalScore, setFinalScore] = useState<number | null>(null);
+  
+  // Calculate score on game-won
+  useEffect(() => {
+    if (gameStatus === 'game-won') {
+      const score = calculateScore(timeValue, totalKeystrokes);
+      setFinalScore(Math.min(1000, Math.max(0, score)));
+    }
+  }, [gameStatus]);
+  
+  return {
+    timeValue,
+    totalKeystrokes,
+    finalScore,
+    // Additional metrics
+  };
+}
+```
+
+**NEW:**
+```typescript
+export function useScore(/* dependencies */) {
+  // Returns raw metrics only - no calculation
+  // Score calculation moved to consumer
+  
+  return {
+    timeValue,
+    totalKeystrokes,
+    // Additional game-specific metrics
+    // finalScore removed - consumer responsibility
+  };
+}
+```
+
+Add note:
+```
+**Change in v2.3+:** ScoreManager is now a pure data collector.
+All score calculation has been moved to the consumer.
+This provides flexibility and allows games to:
+- Provide utility functions for standard scoring
+- Allow consumers to implement custom scoring
+- Keep the hook focused on metrics collection
+```
+
+## Migration Guide for Games
+
+For games updating to this pattern:
+
+1. Remove `finalScore` from `ScoreManager` type
+2. Remove score calculation logic from `useScore` hook
+3. Export a `calculateScore()` utility function
+4. Update `gameOver` option to accept function receiving `scoreManager`
+5. Remove `timeLimit` logic from `useScore` (delegate to consumer)
+6. Document the new scoring approach in gameInfo
+
+## Benefits of This Pattern
+
+✅ **Pure Data Collection** - ScoreManager has no side effects  
+✅ **Separation of Concerns** - Scoring logic is independent  
+✅ **Flexibility** - Consumers control both scoring and game-over  
+✅ **Testability** - Scoring functions can be tested in isolation  
+✅ **Reusability** - Metrics available for any custom logic  
+✅ **Clarity** - Clear boundaries between collection and calculation
