When you play online slots with bonus rounds, you get the chance to win extra prizes. The prize money is based on the winning combinations of symbols, and it can be life-changing for real-money players. These features are designed to increase your chances of winning big, especially when playing progressive jackpot slots. They also come in handy when you want to try out a new slot game without investing any money.
These free online slot games with bonus rounds are easy to find and can be played on both desktop and mobile devices. They allow you to try out the different bonus features and become familiar with how they work before you start playing for real money. These free games also have the same high-quality graphics and gameplay as their real money counterparts. If you’re a first-time player, it’s best to start out with free slot games that have simple rules and easy payouts before moving on to more complex real-money games.
The most popular free slot games online with bonus rounds are those from NetEnt, including Starburst and Gonzo’s Quest. They are easy to understand, with a single pay line and icons grouped together in rows on the reels. They also offer plenty of ways to create winning successions, with cascading symbols and tumbling reels that add up your wins.
Other developers offer a variety of free slot machines with bonus features. Pragmatic Play, for example, has a huge following in Europe with its video slots. Their games include Wolf Gold, which offers multiple multipliers and a free spins round, as well as Dog House, which is more traditional and has a progressive jackpot.
Another feature that makes online slot games so popular is the fact that they can be themed to any subject or character. There are slots based on music, TV shows, movies, and even popular brands. Motorhead fans can enjoy the Ace of Spades theme on NetEnt’s Motorhead video slot, while Jurassic Park fans can play games based on the movie franchise. These free games are a great way to enjoy your favourite franchises without any risk.
Some free online slot machines with bonus rounds include mini-games, where you can select objects to win additional cash prizes or advance in a game’s main story. These mini-games can vary in complexity, from FPS shooters to simple platform games. They are a great way to pass the time between spins on a slot machine and make your gambling experience more fun.
Bonus rounds can be triggered in two ways: they can pop up randomly, or you can trigger them when you land a specific number of scatter symbols. Depending on your slot provider, extra rounds may be available both in demo versions and in real money slots. The number of scatters you need to land to trigger a bonus round varies between games. Some providers have even developed a game where you can trigger them every time you hit a particular combination of symbols.
