3. Game Modes

Daily Tournament

Every day, players compete on a global leaderboard. At 11pm EST, prizes are distributed to top 3 unique winners.

🏆 How It Works

• Unlimited free practice (unranked, learn the game)
• Ranked games: $0.75 each or $3.00 day pass
• Top 3 unique players win: 1st (50%), 2nd (30%), 3rd (20%)
• 90% of entry fees go to prize pool
• Retroactive upgrade: Pay $0.75 after free game to make score count!
• 🐦 Early Bird Bonus: First 50 daily payers get 2 tries for $0.75!

📊 Two Leaderboard Views

💰 Money Leaderboard: Best score per unique player. Only paid/upgraded scores. Top 3 win prizes.
📊 Full Scores: All individual games (toggle view). See every score, track your progress. Practice scores faded.

🔄 Retroactive Upgrade

Max 3 upgrades per day. Must upgrade same day before 11pm EST.

1v1 Challenges

Challenge friends to beat your score. Winner takes the pot. Every challenge is a referral - if your friend is new, you earn 10% of their future games for 30 days.

🎯 Challenge Tiers

WIN $5 → Entry: $3 each (winner gets $5, platform keeps $1)
WIN $25 → Entry: $14 each (winner gets $25, platform keeps $3)
WIN $100 → Entry: $55 each (winner gets $100, platform keeps $10)

🎯 Challenge Flow

1. Finish game with a great score
2. Select challenge tier: WIN $5 | WIN $25 | WIN $100
3. Share link via text, WhatsApp, social
4. Friend accepts, pays entry, tries to beat your score
5. Winner takes the pot!

📢 Broadcast Challenges (1-to-Many)

Challenge up to 100 people with one link. Escrow locked on creation, each match is independent. Win some, lose some - every acceptance is a chance to win!

4. Prize Distribution

Dynamic prize distribution scales with player count and rewards top performers fairly.
