Movies are big business, and that extends to the gambling world. Successful games such as Iron Man have already spawned sequels, while other classic titles such as Jurassic Park and Ghostbusters have also been developed into games. IGT is one game designer which was quick to develop games from movies, and as games have become more complex, more has gone into the design. Themed games will always use symbols and music which relate to the theme, but they can now also include animations and real video footage from the movie to enhance the gaming experience. Many bonus features are launched with some footage or action from the movie, and this acts as a reward for the player when activating a bonus round.
TV Shows have not escaped the attention of games developers either, with cult programmes like Game of Thrones, South Park and Star Trek all undergoing the slot treatment. Again, these games use graphics and animations that will appeal to fans of each particular show. If you happen not to like a certain theme, the game is best avoided, as it can become quite tiresome watching footage or animations of a theme you have no interest in. Thankfully there are so many different themed games out there, that there really is something for everyone.
Music-based games have always been popular, and some of the greatest bands have been used as a theme for slot machines. The likes of Kiss, Guns N' Roses, and Elvis have all had games based on them, and it is a treat for fans. The Kiss online slot, for example, plays familiar guitar riffs every time the reels spin, with additional music being played when winning combinations hit. Entry into the bonus round features a generous piece of real concert footage of the band, and one of their tracks plays from start to finish while you play the bonus round. There is more concert footage when the bonus game ends and it’s a great example of how a slot can be made more entertaining via the theme.
Comic Book games are always popular, perhaps because they appeal to the inner child that wants to play. Software providers have taken advantage of this by developing games from a wide range of comic book themes, including games based on The Avengers, Batman and X-Men.
Historical eras are another popular theme among game developers, with ancient Egypt and ancient Rome being two of the favourite themes that have spawned a multitude of different games. Famous Egyptian-themed titles include Queen of the Nile II, Cleopatra’s Gold, and Book of Ra; while popular Roman-themed titles include the likes of Spartacus Gladiator of Rome and Caesar’s Empire.
