Important Rules

•Minimum bet: 0.001 ETH for single numbers, 0.01 ETH for outside bets
•Maximum bet: 10 ETH total per round across all bets
•0 and 00 are green - they lose all outside bets (Red/Black/Odd/Even/High/Low/Dozens)
•Once betting closes (after 45 seconds), you cannot add or remove bets
•Late bets automatically go to the next round
•Winnings are paid out automatically after each round
•All spins are provably fair using Chainlink VRF (when live on-chain)

Tips for Beginners

💡Start with outside bets (Red/Black/Odd/Even) - they have better odds but lower payouts
💡Single number bets (35:1) are high risk, high reward
💡You can place multiple bets in one round - mix high and low risk!
💡Watch the hot/cold numbers to see which numbers are hitting frequently
💡Set a budget and stick to it - responsible gambling is key
💡Demo mode is perfect for learning before playing with real ETH
