Expert / Extreme (for speed-solvers)

If this is your first global event, start with Medium or Hard before attempting Expert challenges.

Step 4: Check the Challenge Rules

Every event has its own rules. Pay attention to:

Hints → Usually disqualify your score
Pausing → May disable leaderboard ranking
Errors → Some events penalize mistakes
Timer rules → Fixed time vs fastest completion
Submission → Automatic or manual

Once the puzzle loads:

Focus on accuracy first
Use pencil marks wisely
Avoid backtracking too often
Stay calm—speed improves with consistency

The global leaderboard will update as soon as you submit the solution.

Step 6: View the Leaderboard After Completion

Most global challenges provide:

Real-time ranking
Time comparison by difficulty
Country or region-based ranking
Personal best vs global average

Checking this helps you understand how close you are to the top tiers.

How Global Rankings Are Calculated

Each event may use different scoring systems, but most include:

1. Completion Time

Fastest time wins. Pure and simple.

2. Accuracy

Zero mistakes gives you the highest ranking weight.

3. Difficulty Multiplier

Harder puzzles reward higher ranking points.

4. Participation Streak

Daily participation can boost your long-term ranking.

Some sites combine these into a composite score; others use a pure time-based system.

Tips to Improve Your Global Challenge Performance

1. Warm Up with an Easier Puzzle

A quick warm-up improves:

Pattern recognition
Number scanning
Early decision-making speed

Just like sports, your brain performs better after warming up.

2. Use Pencil Marks Strategically

Don't fill the entire grid with marks. Focus on:

Naked singles
Hidden singles
Strong pairs

Less clutter = faster solving.

3. Master Mid-Level Techniques

To consistently rank high, learn:

Naked pairs / triples
Hidden pairs / triples
Pointing pairs
X-Wing basics

These dramatically reduce solving time.

4. Avoid Guessing

Guessing increases mistakes and reduces ranking accuracy.

5. Replay Past Challenges

Many platforms allow replaying yesterday's puzzle.

This helps you:

Identify weak points
Compare solving paths
Track improvement
