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.

FAQ On Bonus Rounds

The best online slots are the source of excitement and enjoyment for players. When it comes to free slots, the size and frequency of payouts don’t matter because you can’t really win anything when playing in demo mode. When choosing a free slot, you need to consider other factors, such as design, plot, theme, and extra features. A newbie can easily get lost in the variety of one-armed bandits. For starters, we recommend that you focus on classic slots and advanced 3D slots.

If you’re playing for real money, you definitely can! During free spins, your winning chances are higher than usual. At the same time, we know how you can make some amazing profits without spending your own bankroll. You have two options:

• You can get a no-deposit bonus and use it to win a round sum.
• You can monitor gambling sites for promotions. It’s not uncommon that online casinos encourage players with free spins. Keep in mind that such special offers are limited in time. For example, a promotion can only be valid for 2-3 hours, with free spins available for 30-40 minutes. Stay alert and don’t miss your chance to get your hand on free spins!

If you’ve won free spins while playing a real-money slot, you have all chances to fatten up your bankroll. Every winning combination you land during free spins generates a real money profit.

You get an opportunity to make a specific number of spins without spending your bankroll. In other words, the casino awards you with free spins that cost you nothing.

In some titles, you can only land high-paying symbols during free spins, which is fantastic. All these perks make free spins a brilliant opportunity to make some amazing profits!
