Slot Machines and Bingo

Bingo sites do big business and create thousands of winners online, but most realise that to attain success they need to offer something more than the basic 75 and 90 ball games. As such you can find slot games on many of the world's biggest sites, offering a variety of play types and themes to keep you interested and coming back for more.

War of the Worlds slot machine

One interesting take on the slots offered by Mecca Bingo is the War of the Worlds, a 100 line game in which you can enjoy music and imagery based on the Jeff Wayne musical adaption of the H. G. Wells novel. Many slot games have less than stellar themes which are not really enough to make the playing of them memorable, but some slots like this go above and beyond in order to please customers and keep them engaged.

Sticking with popular themes big name TV shows have regularly been attached to slot games on bingo sites. At the moment there is no bigger money spinner than The X Factor, even with most of the UK cast making the jump with Simon Cowell to help launch the show in the US. With Take That star Gary Barlow signed up to judge the UK edition in 2011 there looks to be some life in the franchise yet and you can get your fill of X Factor related content at specific slot games on bingo sites.

Now we have covered the kind of franchises you can expect to see on the slot games operated by bingo sites, let us look at what kinds of slot games you might find. Jackpot slots which have cumulative totals running into the millions are often available, letting you have the chance to take home a very appealing pay packet. Multi line slots which allow for various strategies and potentially huge bonuses are also common, as are the single line slots which have a more classic feel and will put you right in the thick of the action.

Casino slots which mirror the kind of visually stimulating games you might expect to see on dedicated sites are also a big part of bingo sites online and you can really take your pick of the best or dip in and out of different games until you find the right one. Check to see whether the slots are browser-based or require a download, as the best sites will let you know what is required so that there are no nasty surprises.

Due to online gambling legislation sneakily passed by Congress in 2006, online casino operators face difficulties in operating in the US market. The result of this is a reduction of choice for American players.

The Dark Knight

The Dark Knight slot machine

The Dark Knight arrives to Microgaming online casinos! Fans of the comic series and slot machines will definitely not be disappointed with this one, its only major problem being that it cannot be played for free.

This will become known as the Batman Slots Game, as it is poised to become one of Microgaming's most popular casino slot games.

The graphics and special effects are superb, with cinematics interspersed along the game as you unlock features like free spins and a bonus round. When you score a "Big Win" you will be shown action-packed scenes from the movie.

The Dark Knight slot machine

Like with The Lord of the Rings slot, Batman Slots uses a special effect named Cinematic Spins. As you spin the reels, the reels will become transparent and action sequences from the film will play in the background. Microgaming calls this a whole new technology, dubbing it "Cinematic Spins".

On the main game screen itself there is plenty of animated stuff going on. For example, at any time in the game, Batman will appear and transform one of the reels into a stacked Wild. Joker will also show up to drop a bomb on the screen, revealing a cash price in the process.

For some reason Microgaming decided to make this game very dark, too dark. The game can be appreciated more by increasing the brightness of your monitor.

Be aware that this is a progressive slot machine, which unfortunately means that you can only play it with real money, not with a fun account.

The Dark Knight slot machine

The progressive jackpot is played out in the roulette wheel round, where you will win one of four progressive jackpots, the biggest of which would make you a millionaire!
