The payout of a slot machine is determined by a random number generator, and it is not influenced by the age of the machine. However, some players may believe that new machines are more likely to pay out to attract customers, but this is not supported by evidence.

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.
