Featured USA Casino

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.

Among the reputable US-friendly casinos, we consider the RTG-powered casinos to be the clear winner, as the other softwares are simply not as good.

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!
