How to test your betting system
Betting systems can't overcome the house edge. I present four different kinds of evidence as to why that's true in my article about betting systems. Centuries of investigation, professional mathematicians, and countless computer simulations all say the same thing: betting systems simply don't work. But if you're undaunted and really want to test your system, read on.
The wrong way to test your system is to gather random roulette spins, baccarat rounds, or craps rolls and then apply your system to it. The reason this fails is that it's impossible for you to hand-check several thousand rounds. After a mere thousand rounds your system might show a profit out of dumb luck, while with most other sets of data (or real-world experience) it would fail miserably. So, forget the idea of hand-checking round results against your system.
The only way to do test a system properly is to run a computer simulation (either one long session of millions of rounds, or thousands of short sessions). Running a computer simulation means either hiring someone to write the program (probably $100 would do it), or learning how to program it yourself (would probably take about a week). To hire someone, try Fiverr or Upwork. To learn programming, try Udemy, Code Academy, or Learn Python.
How the numbers are generated
Some people hear that computers don't generate “real” random numbers, they generate “pseudo-random numbers” (true), and therefore conclude that computers are inadequate for testing betting systems, and that their systems can beat the real world of a casino even if they can't beat the numbers generated by a computer (completely dead wrong). For all intents and purposes, the numbers generated by Xorshift128+ or any of the other modern algorithms are virtually indistinguishable from real random numbers. They pass batteries of statistical tests for randomness, including frequency distribution, gaps, repetition, and predictability. The bottom line is, you can't tell the computer-generated output from the real thing, and the statistical quality is virtually the same.
