Welcome to Online Casino Slot Machine

Welcome to Online Casino Slot Machine, the home of online casino slots! Slot machines are one the most popular ways of gambling today. There are so many kinds of slot machines that one could spend his entire lifetime playing slots and would never come close to having played them all. The history of the slot machine goes back over a century, and over this period it has evolved into becoming the most played gambling game ever.

Castle Builder slot

Castle Builder is a new slot machine released by NetEnt in which the goal is to build various "royal family" castles and marry the princes and princesses to other aristocratic entities (and not necessarily people!). This is one of the longest thematic slot machines we have come across, as once it looks like you finished the current castle quest, the next one opens up and you in a sense "start all over again", but with different/heightened game parameters. Overall this is a very entertaining slot machine game worth checking out.

Dracula slot

Dracula is a new slot machine released by NetEnt featuring 40 active paylines across 5 reels. Aside from the Dracula-themed symbols, animations, and sounds, bonus features include the regularly-appearing Bat Feature, in which bats will swirl all over the screen and turn many symbols on the reels to the same ones, landing the player massive cash. Another bonus feature is the Free Spins round, in which you get not only 10 free spins but the Bat Feature on every spin during the free spins bonus!

Nonetheless, the Game of Thrones slot machine will keep fans of both the show and online slot machines entertained for a while.

Dark Knight Rises

Dark Knight Rises is the sequel to The Dark Knight slot machine released along with the film in 2012. This game is even better than its predecessor, with 5 reel and 243 way to win, formely known as winning paylines. Special aspects and features include: Expanding Wilds, Split Wilds, Symbol Scramble, Free Spins Accumulator, Free Spins Feature, and the bonus round. Graphics and sound are superb, as you might expect. Perhaps the only minor flaw is that, like its prequel slot game, Dark Knight Rises is very dark, and would look better at night or with monitor brightness turned up a notch.

Great Griffin: For February 2012, Microgaming brings us yet more online slots games, the most impressive of which is Great Griffin.

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.

Grand Parker Casino is a great place to play for USA based players. It uses state of the art software from Real Time Gaming and offers one of the best and most secure payment processing systems around so that you can be sure your deposits and withdrawals are dealt with safety and confidence.

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!
