Online Casinos regularly introduce new slot games ( also known as fruit machines ) to their portfolio. Microgaming and Rival Gaming tend to introduce new slot games on a monthly basis, so you can be sure that you will never be bored. RTG sometimes go for quite a few months without introducing any new slots, but you can be sure that when they do - they certainly don't disappoint as they bring out 5 or 6 at the same time and always more exciting than the previous slot games. Playtech does not often introduce new slots, but when they do - again you can be sure that they were well worth waiting for! Whilst we try and keep up to date with the latest slot games launched - it is practically impossible to do this across all of the gaming software programs, therefore we have listed the most popular new games below. Bear in mind that all the online casinos offer free online slots for you to play without using your own money in order to test out the slots first.
