While the roulette ball has no memory, mathematicians have continually devised complex betting systems.

Betting strategies do not change the house edge, but they do dictate how you stake your money.
The Martingale System Explained
This progressive system is incredibly simple: you double your bet after every single loss.

When you finally win, you recoup your losses and secure a profit equal to your original wager.

You progress through the sequence (1, 1, 2, 3, 5, 8...) when you lose, and step back when you win.

While safer, it also takes longer to recover losses compared to doubling up.
The Flat Progression System
Conversely, you decrease your wager by one single unit following a winning spin.

This approach assumes that over time, wins and losses will balance out almost equally.
