Yes, they are. Slots, new or old, have to meet strict standards with regards to safety, security and fairness. The random number generators (RNGs) that determine the result of every slot spin have to be tested by third-party agencies. A game only passes the test if its random and fair. In turn, regulators such as the UKGC won’t authorise a game or licence an online casino if it doesn’t have certifiably fair products. Therefore, when you play new slots online, you can be confident that they’re 100% fair.
