Some of the better sites, like Paddy Power and LeoVegas, will often have no deposit offers available for new players where they can get from 5 spins up to 100 free spins on sign up to try out the particular slot games. Even popular sports betting sites will include these freebies in their promotional welcome offers, such as Betvictor and Paddy Power. They are also available at bingo sites, and dedicated slot sites.
