Bonus Features in Popular Casino Games

Bonuses in slots are very important, especially in new online slots. As was already mentioned above, the most popular games on internet casinos have amazing extra features. Thanks to them, you will not only enjoy more versatile gameplay but also win far more money. There are different types of features used by different software providers. However, most bonuses are similar, so you will easily get used to them.

Here are the bonus features found in top slot machine games on Ra Casino:

  • Free Spins. Almost every gambling studio offers them. You can activate them with specific symbols to spin the reels without wasting any real money. Most of the time providers offer free games in their slots with additional bonus features, like extra wilds or moving reels.
  • Wilds. Yet another must-have element in online slots. They not only serve as the highest-value symbols but also replace any other symbol on the playing field to help you build winning combos. In some games, wilds trigger bonus rounds or multiply the overall winnings. As a bonus feature, Wilds can be divided by the type: Expanding, Stacked, Sticky, etc. 
  • Scatters. Special symbols that trigger bonus features such as extra round or free spins, as well, as giving payouts even if they're not collected in straight payline. Unlike standard icons, they can appear on any reels, and mostly 3+ collected Scatters give a player pretty nice winning.
  • Gamble Features. Some of the best online slots have this feature for risky players. Gamble, or Risk round can be launched after every successful spin of the reels. There are different ways casino game providers adding Gamble rounds to their games, but most popular is "Guess-A-Suit-Color" mini-game. In it, the player must guess the color of a suit of the closed card: red or black. If you make the right choice, you will double your overall award. Otherwise, you will lose everything you have won.
  • Respins. This feature has something in common with free spins. In some popular online slot games, after each successful spin, reels can make an additional spin to form a new combination for no cost (as FS do, but only for 1 spin). This way players can win a huge amount of money by paying for a fewer amount of spins!
  • Multipliers. These are pretty straight forward - symbols that can give a player a multiplier to all wins while collected in a winning combination. Starting from x2, multipliers can significantly increase the player's bankroll, especially, if multipliers are being dropped in bonus games.
  • Bonus Games. The combination of all bonus features of the game presented in a single bonus round. For example, the Demi Gods slot by Spinomenal has a bonus game, where the player is on adventure in different locations with different additional extra features: Free Spins, Cascading Reels, Stacked Wilds, etc. Some games have a Pick-An-Item bonus game, where the player must pick an item from the screen which gives a payout.

As you can see, bonuses are very exciting. That is exactly why so many people enjoy games of chance with extra features. Pretty much all the popular slots come with bonuses nowadays. They are indeed very fun, so you should try playing them! However, those who prefer simple slot machines without bonuses can stick to retro fruit slots with three reels. Such kind of games does not have bonuses at all.
