🌟 Key Features & Strategic Tools:

1. 🏆 Lotto Master’s 5 Strategic Picks
• Generates 5 calculated combinations based on frequency formulas, filtering out approximately 20 low-probability excluded numbers.

2. 👥 Lotto Expert Common Number Extraction
• Aggregate meaningful combinations and extract common overlapping numbers to pinpoint high-probability candidates.

3. 🔢 Full Sequence Numbering (1 to 8,145,060)
• Every single 6/45 combination is mapped to a unique 1-to-1 sequence number.
• Jump directly to any combination by its index or generate numbers from specific numeric intervals.

4. 📊 Real-Time Historical Winning Simulation
• Instantly calculates all-time winning performance (1st to 5th prize counts) across all historical draws for any combination.
• Know immediately if a combination has already hit 1st place in past draws or has never won.

5. 🎛️ Interactive Number Pad & Advanced Constraints
• Generate combinations via Automatic, Semi-Automatic, or Manual modes on a 1–45 number grid.
• Configure Fixed Numbers (must include), Excluded Numbers (must exclude), and Partial Inclusion group quotas.
• Real-time display of possible combination counts under active constraints.
• Filter combinations by historical rank patterns and same-ending-digit pairs.

6. 📈 Appearance Frequency & Theoretical Benchmarks
• Analyze number appearances over customizable draw intervals (recent 5, 10, 50, or custom spans).
• Compares empirical occurrences against theoretical probabilities, with optional bonus number toggling.

7. ⏱️ Draw Intervals & Cold Number Dormancy
• Tracks round gaps between consecutive appearances for all 45 numbers.
• Sort numbers by non-appearance periods to identify cold or overdue numbers.

8. 🔗 Co-Appearing Number Analysis
• Check how frequently specific sets of numbers (pairs, triplets) have appeared together historically.
• View exact historical draw rounds and verify joint appearances against theoretical expectations.
