The features you will encounter depend on the games that you play. Classic slots tend to keep bonus features to a minimum and rely heavily on the traditional slot-machine layout and a handful of fixed paylines. More advanced slots will offer extra features, like Wilds, Scatters or bonus rounds. You'll come across plenty of unique slots, games with one-of-a-kind bonuses and entirely new payline systems, so make sure to read through the rules before you play.
