Ever since slot machines were first invented, players have tried to come up with ways of tricking them into giving them more money. From tracking the order in which symbols came up to manipulating the lever, there have been slight chances of doing this, but now that online casinos use random number generator software for their games, it is nigh on impossible to trick them into paying you more than they should.
The fact that slots are based on luck rather than complex strategy also makes them a more accessible game to play, reaching out to a much wider player base than table games like blackjack and video poker do. This coupled with the massive percentage of return prizes on offer has made them one of the most popular casino games online.
Unlike land-based machines, which have to be programmed to display specific combinations of symbols at the end of each spin, online slots create a new random sequence every millisecond. These sequences can then be compared with the results of previous spins using a mathematical algorithm that communicates with the RNG over the internet.
Many online slot players also enjoy a progressive jackpot, which keeps growing until a player hits the winning combination. This is often a combination of symbols or a bonus game, but some games also have fixed jackpots. Branded online slots are the latest trend, with titles based on popular movies and television shows, sports celebrities and rock bands being developed through licensing agreements.
