Monte Carlo Simulator

Vesta Play Monte Carlo Simulator: Mathematical Guide to Strategies

VestaPlay Monte Carlo Simulator uses mathematical modeling to analyze probability distributions of results from different betting strategies in crash games. The simulator doesn’t predict future outcomes but demonstrates statistical characteristics of strategies over a large number of trials. Monte Carlo method is based on repeated random experiments to obtain statistical data about the distribution of possible outcomes.

🧮 Mathematical Foundations

Crash Multiplier Distribution

The simulator uses realistic probability distribution:

P(multiplier = 1.00) = 3.0% (instant crash)
P(1.00 < multiplier ≤ 1.50) = 7.0%
P(1.50 < multiplier ≤ 2.50) = 20.0%
P(2.50 < multiplier ≤ 4.50) = 30.0%
P(4.50 < multiplier ≤ 7.50) = 25.0%
P(7.50 < multiplier ≤ 15.0) = 10.0% P(multiplier > 15.0) = 5.0%

Expected value of crash multiplier:

E[X] = Σ(x × P(x)) = 4.32

Probability of successful cashout at multiplier M:

P(success) = P(multiplier ≥ M)

Profit/Loss Formula

For bet `B` and cashout multiplier `C`:

Profit = {
B × (C - 1), if multiplier ≥ C
-B, if multiplier < C
}

🎲 Betting Strategies

1. Fixed (Fixed Bet)

Mathematical Description:

B_n = B_0 for all n

Where:
– `B_n` – bet in nth round
– `B_0` – initial bet

Characteristics:

• Risk: Low
• Volatility: Medium
• Expected Value: E[Profit] = B × (P(success) × (C – 1) – P(failure))
• Variance: Var(Profit) = B² × [P(success) × (C – 1)² + P(failure) – E[Profit]²]

Advantages:

• Simplicity and predictability
• Controlled risk
• Stable volatility

Disadvantages:

• No loss compensation
• Linear balance growth/decline

2. Martingale

Mathematical Description:

B_n = {
B_{n-1} × 2, if previous round was a loss
B_0, if previous round was a win
}

Risk Analysis:
Probability of k consecutive losses:

P(k consecutive losses) = (1 - P(success))^k

Expected bet after k losses:

E[B_k] = B_0 × 2^k

Critical Analysis:

• Gambler’s Problem: Infinite loss series are possible
• Limitations: Maximum bet and bank limits
• Bankruptcy Risk: P(bankrupt) → 1 in infinite play

Expected Value:

E[Profit] = B_0 × [P(success) × (C - 1) - P(failure)]

(Remains unchanged but with exponentially growing risk)

3. Anti-Martingale (Reverse Martingale)

Mathematical Description:

B_n = {
B_{n-1} × 2, if previous round was a win
B_0, if previous round was a loss
}

Logic: Increase bets during winning streaks

Streak Analysis:
Probability of k consecutive wins:

P(k consecutive wins) = P(success)^k

Expected bet after k wins:

E[B_k] = B_0 × 2^k

Advantages:

• Capitalizes on winning streaks
• Limited risk during losing streaks

Disadvantages:

• Requires frequent wins
• Quick bet reduction after loss

4. Fibonacci

Mathematical Description:
Uses Fibonacci sequence: F₀ = 1, F₁ = 1, Fₙ = Fₙ₋₁ + Fₙ₋₂

B_n = B_0 × F_k / F_0

where k – number of losses since last win

Bet Sequence: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55…

Mathematical Properties:

• Golden Ratio: lim(Fₙ₊₁/Fₙ) = φ ≈ 1.618
• Growth Rate: Exponential but slower than Martingale
• Recovery: Requires fewer wins to return to initial bet

Risk Analysis:

Maximum bet after k losses = B_0 × F_k

5. D’Alembert

Mathematical Description:

B_n = {
B_{n-1} + 1, if previous round was a loss
max(B_{n-1} - 1, 1), if previous round was a win
}

Principle: Pyramid system with 1 unit step

Mathematical Analysis:

• Linear Growth: Unlike exponential in Martingale
• Limited Risk: Maximum bet grows slowly
• Equilibrium Theory: Based on win/loss balance assumption

Expected bet after k steps:

E[B_k] = B_0 + |wins - losses|

6. Conservative

Mathematical Description:

B_n = min(B_0, 0.02 × Current_Balance)

Principle: Fixed percentage of current balance (maximum 2%)

Risk Analysis:

• Adaptivity: Bet decreases with losses
• Capital Protection: Automatic risk reduction
• Long-term Sustainability: Minimal bankruptcy probability

Expected balance change:

E[ΔBalance] = 0.02 × Balance × [P(success) × (C - 1) - P(failure)]

7. Aggressive

Mathematical Description:

B_n = min(1.5 × B_{n-1}, 0.1 × Current_Balance)

Principle: Progressive increase with 10% bank limit

Volatility Analysis:

• High Risk: Maximum bet can reach 10% of bank
• Potential Returns: Exponential growth during winning streaks
• Drawdown Risk: Significant balance fluctuations

📊 Risk Analysis

Value at Risk (VaR)

Definition: VaR₉₅ – maximum expected loss with 95% probability

VaR_95 = 5th percentile of final balance distribution

Conditional VaR (CVaR)

Definition: Average loss in worst 5% of cases

CVaR_95 = E[Loss | Loss ≤ VaR_95]

Sharpe Ratio

Formula:

Sharpe Ratio = (E[Return] - Risk_Free_Rate) / σ(Return)

Where:

• E[Return] – expected return
• σ(Return) – standard deviation of return
• Risk_Free_Rate – risk-free rate (usually 0)

Interpretation:

• SR > 1: Excellent return per unit of risk
• 0.5 < SR < 1: Good return
• SR < 0.5: Low efficiency

Maximum Drawdown (MDD)

Definition: Maximum fall from peak to trough

MDD = max(Peak - Trough) / Peak

🎯 Practical Application

Optimal Strategy Parameters

Bankroll Management

Kelly Criterion (bet size optimization):

f* = (p × b - q) / b

Where:

• f* – optimal bank fraction
• p – win probability
• q = 1 – p – loss probability
• b – win-to-bet ratio

Practical Rule: Use 25-50% of Kelly optimal bet to reduce risk.

Strategy Diversification

Recommended strategy combinations:

• 70% Conservative/Fixed for stability
• 20% Fibonacci/D’Alembert for moderate growth
• 10% Aggressive for potentially high returns

🔬 Statistical Significance

Number of Simulations

For statistically significant results:

• Minimum: 1,000 simulations
• Recommended: 5,000-10,000 simulations
• Accuracy: ±1% at 10,000 simulations (95% confidence interval)

Confidence Intervals

For mean value:

CI_95 = Mean ± 1.96 × (σ / √n)

Where:

• σ – standard deviation
• n – number of simulations

⚠️ Important Warnings
