Betting Odds Game – Quick Start Guide
Start with 1,000 coins and grow your bankroll by identifying mispriced odds and sizing your bets optimally. Beat the house by finding favorable odds!
🎰 How the Game Works
Each round features a number of independent events for the outcome of the following elements:
- Two dice 🎲🎲 are rolled (six-sided)
- Two cards 🃏🃏 are dealt from a standard deck
- Three coins 🪙🪙🪙 are flipped
You can bet on various outcomes like:
- “Both dice show even numbers”
- “Sum of cards is greater than 10”
- “Exactly two coins show heads”
📊 Understanding Odds
The house presents odds in fractional format (e.g., 3:1)
- 3:1 means risking 1 coin to win 3 coins profit
- To find implied probability: denominator ÷ (numerator + denominator)
- Example: 3:1 odds = 1÷(3+1) = 25% implied probability
💡 Basic Strategy
- Calculate true probability of each event
- Compare to house odds – if house offers better odds, bet!
- Size your bets using Kelly Criterion
- Look for arbitrage – combine bets for guaranteed profit
🔐 Special Bets
