Another Roulette System Test: Do These Strategies Really Hold Up?

Alright, let's dive into this. I’ve been tinkering with a few roulette systems again, and since this thread is all about testing strategies, I figured I’d share my latest experiment. I’m not here to sell anyone on a "sure thing"—honestly, I’m starting to think most of these systems are more about hope than math. But numbers don’t lie, so I ran some tests to see if a couple of popular strategies could actually hold up under scrutiny.
First up, I looked at the Martingale. You all know it: double your bet after every loss, reset after a win. Sounds simple, feels bulletproof—until it isn’t. I simulated 10,000 spins using a basic European wheel (single zero, 2.7% house edge). Starting bet was $10 on red, bankroll capped at $5,000 to keep it realistic. The idea is you’re supposed to recover losses eventually, right? Well, in theory. After about 300 spins, I hit a streak of eight blacks in a row. My bet ballooned to $1,280, and the next spin was black again. Poof—bankroll gone. Over the full 10,000 spins, I busted out 12 times. Sure, there were stretches where I was up a couple hundred bucks, but those losing streaks hit hard and fast. The math checks out: the house edge doesn’t care about your doubling plan. It’s relentless.
Next, I tested the D’Alembert, which feels a bit less reckless. You increase your bet by one unit after a loss, decrease by one after a win. I used the same setup: $10 base bet, $5,000 bankroll, 10,000 spins. It’s slower, less heart-attack-inducing than Martingale. Early on, I was hovering around even, sometimes up $50, sometimes down $30. But the problem is the grind. After a few thousand spins, I noticed the losses creeping up. By spin 7,000, I was down $400, and the system’s “balance” just couldn’t keep up with the variance. The final tally showed a net loss of $620. Not catastrophic, but not exactly a glowing endorsement either.
I also threw in a quick test of a custom hybrid I’ve seen floating around—call it the “Fibonacci-Martingale mashup.” You follow the Fibonacci sequence for bets (1, 1, 2, 3, 5, etc.) but reset to base after two wins in a row. I won’t bore you with the full breakdown, but it was a mess. The progression gets steep fast, and the reset rule didn’t save me from a $2,000 hole after a bad run. Honestly, I ditched it halfway through.
Here’s the deal: none of these systems change the odds. The wheel doesn’t know or care about your betting pattern. That 2.7% house edge is like gravity—it’s always there, pulling you down. I’m not saying these strategies can’t be fun or give you a hot streak to brag about. But if you’re banking on them to beat the casino long-term, my numbers say you’re fighting a losing battle. I’m planning to test a few more obscure ones next—maybe Paroli or something flat-betting-based. If anyone’s got a system they swear by, drop it here, and I’ll crunch the numbers. But don’t hold your breath for a miracle.
