Calculation methodology

Slot Stat is an independent platform focused on slot game analytics and statistics. We provide objective reviews and data on gambling products without any direct partnerships with casinos or operators. Our content is intended for users aged 18 and older only. We strongly encourage responsible gambling and compliance with the laws and regulations of your country or region. Any illegal activity is strictly prohibited. By using this site, you agree to our Privacy Policy.

Our platform collects and updates slot machine statistics on a daily basis, ensuring maximum transparency in the performance of providers and game suppliers.
The extended process includes several key stages:

Data Collection

Spin Frequency
A minimum of 1,000 spins per slot per day.

Event Logging
Wins (amount, timestamp)
Losses (amount, timestamp)

Sources
Provider APIs
Direct simulations via emulators

Initial Validation

Reverse Play Principle
Algorithm B “replays” the data in reverse order and cross-checks the results.
In case of discrepancies, data is manually verified
Missing entries and duplicates are monitored
Checking the integrity of the spin sequence (no omissions in the numbering)
Identification and removal of duplicates
Error Logging
Automatic recording of all detected discrepancies (omissions, duplicates, discrepancies) in the log for further analysis

Key Metrics Calculation

RTP (Return To Player)

Volatility

RTP %∑ Wins / ∑ Bets × 100%Long-term return percentage to the player
Volatility (σ ≈)Standard deviation of winsIndicates the spread of payouts

The symbol σ (the Greek letter “sigma”) in math and statistics stands for standard deviation. Volatility is considered low (frequent small wins) when σ < 200, medium when 200 ≤ σ ≤ 1000, and high (rare but big wins) when σ > 1000.

Processing and Visualization

Regular Quality Checks

Weekly Audit: All collected data is reviewed weekly by analytics specialists.

Cross-Verification: Data is compared with open sources such as forums and player reports.

Development Roadmap:

Machine learning integration is planned to forecast anomalies in gameplay data.
The system will also feature automated alerts for suspicious metric values.
Additionally, the platform will expand to cover crash games and live casino content.
