Search for "CS2 roulette strategy" and you will find the same systems again and again: Martingale, reverse Martingale, Fibonacci. They promise steady wins. Here is what they actually do, with simple maths.
How the Martingale system works
You bet on a colour that pays 2x. After every loss you double the bet; after a win you go back to the starting bet. The idea: one win covers all previous losses plus one unit of profit.
It sounds safe — until you look at a losing streak. Starting with 1 coin, after 8 losses in a row you have already lost 1 + 2 + 4 + … + 128 = 255 coins, and your next bet must be 256 coins. All of that to win back 1 coin.
How often do long losing streaks happen?
Take a colour with a 47% chance to win (the exact number depends on the site's wheel). The chance of losing 8 times in a row is about 1 in 160 — it feels rare. But over a session of 200 spins, the chance of hitting at least one 8-loss streak somewhere is roughly 45%. Play a few sessions and it becomes almost certain. One bad streak wipes out hundreds of small wins.
The real problem: the house edge
Every spin has a negative expected value. With a 47% chance at 2x, each 1-coin bet returns on average 0.94 coins — you lose about 6% per bet in the long run. A betting system only changes how you lose (many small wins, then one big loss), not whether you lose. Fibonacci and other progressions work the same way, just slower.
What actually helps
- Decide your budget before you start and treat it as already spent.
- Set a loss limit and a time limit, and stop when you reach either.
- Never raise bets to win back losses — that is the Martingale trap in disguise.
- Use provably fair sites so at least the results are verifiable.
- Roulette is for 18+ only and is not legal in every country — check your local laws.
