First and foremost: what is a bonus game?

As a general rule, in an overwhelming majority of cases, online slots have the base game and bonus rounds and free spins mode in addition to that. 

The base game is the default mode where you can mostly win by getting 3-5 matching symbols on a payline. That's about it. While some base games can have some modifiers and extra features, mostly it's a simple case of landing the matching symbols. 

But to make the slots more fun, profitable and action-packed, the game developers come up with the attractive bonus and free spins rounds and modes that can help you win more and add more thrill to the gameplay. Usually, the bonus rounds and free spins modes will be activated by some sort of a special wild, scatter or bonus symbol combos and will run for a certain number of spins.

Quite often a player will be taken to a separate or modified screen and you might have to perform different actions, make choices, etc. in order to win the bonus round. There are different kinds of bonus games, some more advanced and interactive than others, and we will come across a few different ones in this article.

Different free spins modes

In most cases, the free spins round is activated by landing at least three scatter symbols. However, there could be other ways of triggering it. Once the free spins round starts, you will receive a certain number of free spins, which means that the reels spin for a while without you paying anything per spin. 

The number of free spins that you receive can range anywhere from 5 to 100, but most slots offer on average 10-30 free spins. All online casino players absolutely adore the free spins mode since this is your opportunity to get some extra winning without the extra pay. 

What you can win varies a lot as well because some games might have extra features such as multipliers, modifiers and wilds helping you to win more during the free spins round. There are also slot games where you can choose or be randomly assigned one of the few different free spins mode options with different rules and payouts.

This is another category of the bonus game which is quite popular, and the players are expected to pick and choose different items from a large selection to win cash prizes and multipliers, or of course, you can be unlucky and choose "end of the feature" item.
