You can’t tell if a slot machine is a winning one or not. However, there are features to look out for to see if it is one of the best paying slot games. These include the maximum bet size, the top win value, the RTP and the regularity of the payouts it makes. You can also check the hit frequency to see how often wins land, and how volatile it is. All of these features will give you an idea of the chance you have when playing. However, as slots are luck-based, there’s no guarantee at all.
