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.

A slot is a connection dedicated to one user on a server. For example, a 4 slots server will be able to welcome up to 4 users at the same time. Do I loose my server data when I renew my server ?
