No! The likelihood of victory is always increased by putting strategies into action. The majority of these strategies, like the Martingale Strategy, are based on gradually increasing the size of the bet placed. Online slot and casino game players claim that if these strategies are used correctly, they can increase their chances of winning. It is important to keep in mind that video slots use the RNG (Random Number Generator) principle, which means that it is impossible to predict the results and impossible to guarantee a 100% win rate.
