Playing slot machines primarily relies on luck rather than skill. The outcome of each spin is determined by a random number generator, making it difficult to influence the result through skill.
The truth is that there is no trick to slot machines. They provide random results based on set mechanics and it all comes down to luck. With that being said, not all games are the same, so picking the right options is key, and you can still change the size of the bet throughout the session for better results.
