Online slots are among the most widespread casino games, which offer bonuses. There is a short overview of common bonus features you are most likely to come across while spinning the reels of online slot machines.

Usually these special online slot machines bear the name of Bonus Slots, so we advice you firstly pay attention to this fact. Then you should know that all online bonus slots are divided in several categories, each offering various bonus features. You can find the list of highly popular slots bonuses along with some useful tips below.

1. Wild symbols are slot theme-related symbols appearing anywhere on the reels and substituting any other symbol you lack to get your winning three(or else)-of-a-kind combination. Wild symbols replace other slots symbols automatically. Combine such features of online slots as Wild symbols and multiple paylines and you will sufficiently increase your winning opportunities.

2. Scatter symbols have two functions. The combination of any given Scatter symbols (see the corresponding slots descriptions for this) will either multiply your winnings or trigger you to another level of the game, where you will be able to compete for some additional prize pool.

3. Nudge and hold buttons will help you manage the reels according to your wish. Hold or nudge symbols to get your winning combinations on your own. As soon as reeling stops you’ll be able to adjust missing symbols to collect your prize money!

4. Cascade is another bonus function of online slots. Cascades randomly replace unfitting symbols on the paylines with new ones, increasing your chances to win.

5. Symbol slide is the same as the “nudge” button, but can move only one symbol along the reel.

6. Free spins can be granted to you as a result of scatter symbols combination or other useful feature of online slots you’re playing.

7. Bonus gambling rounds – some combinations of online slots symbols can trigger you to bonus games like scratches, guessing games or mini-games of tricks or skills.

Now that you’re equipped with fresh facts about these bonus features, you know that online bonus slots bring much more entertainment than usual ones.
