The human brain is terrible at understanding randomness. When we see 10 Reds in a row on Roulette, or 15 losses in a row on Blackjack, we instinctively think, “This must be rigged!”
This Streak Calculator proves otherwise. It calculates the true mathematical probability of encountering a specific streak over a large sample size, helping you distinguish between an anomaly and normal variance.
How to Use the Streak Calculator
This tool works for any game with a known win/loss probability (Roulette, Slots, Trading, Flip-coin).
- Win Probability (%): Enter the chance of winning a single round (e.g., 48.6% for European Roulette, 50% for a coin flip).
- Streak Type: Select whether you are analyzing a Winning Streak or a Losing Streak.
- Streak Length: The number of consecutive results (e.g., 10 losses in a row).
- Number of Bets/Trials: The sample size (e.g., “I played 1,000 rounds”).
Example: The “Rigged” Roulette Wheel
You are playing Red/Black on European Roulette (48.6% win chance).
- Scenario: You witness 10 Losses in a row.
- Probability on NEXT spin: Still 48.6% (The wheel has no memory).
- Probability over 1,000 spins: There is a ~49% chance that a streak of 10 losses will happen at some point in a 1,000-spin session.
Conclusion: It is not rigged. It is statistically expected behavior for a long session.
Frequently Asked Questions (FAQ)
What is the “Gambler’s Fallacy”?
The Gambler’s Fallacy is the mistaken belief that if an event happens more frequently than normal (e.g., 10 Reds in a row), it will happen less frequently in the future (Black is “due”). In independent events, the odds never change.
