Today I decided to test the outcome probabilities in the Coin Flip game on Vault777. Allocated $10 for the experiment. The minimum bet on @Vault777Casino is $0.5, so I ran 20 rounds. With an expected 50% win probability and a 2% fee, the expected return is about $9.8. But variance was on my side today! I finished with 14 wins and 6 losses. 70% win rate. That is 4 more wins than the expected 10. Final result: +$3.86. One important detail. Each round was settled separately on-chain. For every new game, Chainlink VRF generates a new verifiable random number. This means each round is independent. Even if you win five games in a row, the next one is still 50/50. The screenshot shows the final moments of my session.
