All of us here like slot machines and yet, each one has his own unique taste: i like classic 3-reel slots; Mark, the guy behind, likes the new 3D slots with crazy graphics and special bonus features; some are looking for casinos that accept Paypal or Visa and some are looking to play free slots. We can go on and on.

Our rating algorithm is based on many different parameters and the outcome is the casinos that are listed here.

Slot Machine Types

Slot Machines are by far the most popular casino game online and offline. Over 80% of wagering happens at the slot machines. There are many types of slot machines online and new ones are invented every few months.

  • Three reel slots: Three reel are the so called classic slots. As the name suggests, they have 3 reels and usually lower number of paylines than the 5-reel slots. Three reel slots are in general more simple and direct. They are the best choice for players that don’t like all the effects and sounds that video or 3d slots have, and just want to see the familiar symbols of Big 7 or Stars and Stripes and to hit spin.
  • Video slots: 5 reel video slots are the next step in the history of slot machines. They have more symbols, offer more paylines, usually 20, 25 or 50, and many times have many additional features such as free spins, bonus rounds and more.
  • 3D Slots: 3D slots are a recent development in slots technology. They combine all the features of video slots with realistic, 3 dimensional symbols and effects. Most 3D slots are based on a certain story line which advances as the game proceeds. 3D slots include popular names such as 2 Million B.C. , The Slot Father and more.
  • Progressive Slots: Progressive slots are slot machines that besides the regular jackpot also offer an additional progressive jackpot. These slots are usually connected to other slot machines in the casino and even to slots in other casinos. When you play a progressive slot machine, part of each bet goes to the progressive jackpot. Progressive jackpots are usually higher than regular jackpots and sometimes reach millions of dollars, but naturally they are harder to win.The downside of progressive slot machines is that since part of the bets is diverted to the progressive jackpot, the regular payout is lower than in standalone slots. Therefore, although it is nice to try and win the big jackpot, we do not recommend playing all your budget on progressive slots.

Slot Machines Online FAQ

Are online casinos safe?

Yes, they are. Licensed online casinos have almost similar security as banks. All your details, personal and financial, are encrypted. The only thing that you need to do on your part is to play only in licensed online casinos. All the casinos listed on Slot Machines Online are licensed, but if we wish to play in a real money casino that is not listed here, make sure that it has a valid license by a reputable licensing jurisdiction.

Do I need to download the software?

There are two ways to play casino games online: first one is by downloading the casino software and the second one is using a flash mode, also called “no download” version. It’s impossible to say which option is better; it mainly depends on the specific online casino you chose. Generally speaking, in Europe, UK, Australia, New Zealand and Canada 50% play at download casinos and 50% in instant play. In US the situation is different and download casinos are more popular. The reason for that the No download casino version of many US casinos is just not good. If you do wish to pay in-browser, here is our list of Best Instant Play USA Casinos.

Two special cases: If you are playing on Mac, tablet or mobile- then you should use the no-download version or an app. On the other hand, if your internet connection is weak – then download version is more recommended.

Yes. Most online casino got adapted to the mobile revolution and offer a mobile version of their games.
