What are free online slots with bonus rounds?

Further Information

What we are talking about here is not online casino bonuses: You don’t have to register or deposit to take advantage of them. What we mean by free online slot games with bonus rounds are the features offered by the games that you can activate by meeting certain conditions.

For example, you can land three scatter symbols and win ten free spins. Or, finding five wild symbols can activate a multiplier award and a “pick me” game.

We’ll give more examples below, but the main theme will always remain the same: Free online slots with bonus are online casino games with a variety of features in addition to standard symbol payouts.

Both classic 3 reel slots and modern slots (including online slots – Canada based) can offer these features, but they are mostly found in in video slots. If you play free online slots with bonus features, you can win an additional prize or increase the amount of your current win.

Are free online slot games with bonus worth playing?

Definitely yes. No matter what kind of feature free slot machines with bonus offer, they will always be worth playing. Because all of these bonus features either offer an additional free chance to win a prize or increase your current payout.

For example, by playing a risk game in 5 reel slots (such as Peggle slots), you can increase the payout amount up to four times. Or, you can trigger a fixed jackpot prize with a pick-me game in classic slots.

There are lots of possibilities and all of them offer an advantage. In short, all free slot machine games with bonus, regardless of their genre, give the player an edge and are worth playing for the same reason.

Activating the feature in free online slots with bonus


All bonus slots work differently: What you have to do to activate the feature is different in all free casino games with bonus rounds. For this reason, we recommend that you first read the paytables of the free casino slot games with bonus.

Both the general rules and how to activate the bonus round are explained in detail in these tables. However, if we make a general evaluation, we can say that scatter symbols are used to activate these features.

This is especially true for free slot games with bonus spins. In order to activate the free spins, at least three scatter symbols usually need to land anywhere on the screen. The number of free spins is determined by how many scatter symbols landed (i.e. 10 spins for 3 symbols, 15 spins for 4 symbols, etc.).

However, as we mentioned above, this does not apply to all online free slots with bonus feature: We recommend that you learn the bonus activation terms of video slots from the paytable before you start playing.

How often you can activate the bonus features is determined by the online casino software and is completely random. In other words, there is no way to know in advance when a feature in free casino slot machine games with bonus rounds will be activated.

Playing online free slots with bonus feature: What to expect?

So, what kind of features are available in free online video slots with bonus rounds and what advantages do they offer? In the list below, you can see what features you should expect from free slots with bonus feature.

However, keep in mind that this is a general list: All pokies are unique and it is, therefore, important that you read the paytable before starting to play.



Gamble/Risk Game
Almost all of the old-school real money slots offer this feature, such as Aristocrat slots or Amatic slots (like Party Time slots). After winning a spin, you can choose to play a game where you try to guess the color or suit of a closed play card. If you guess correctly, you can double or even quadruple the payout.
Free Spin
The most common feature of free online slot machines with bonus games. After meeting a certain condition (usually landing at least three scatter symbols), you win a certain number of free spins. If you win a prize with these spins, it is yours to keep.
A single free spin that can be won after meeting a certain condition, i.e. landing two wild symbols on reels 2 and 4.
Pick Me
A game that asks you to choose from multiple options. It is usually played with closed boxes, and each box has a different reward. Cash money, multiplier, or free spins are available in each box that opens. However, one of the boxes contains an icon that ends the round. The game continues until this box is selected. Betsoft slots offer this feature quite often.
Instant Win
By landing a specific set of symbols (i.e. 5 bonus symbols) you win a cash prize that is higher than the regular symbol payouts. It is like a “mini-jackpot”.
Extra Wilds
After meeting a certain condition (i.e. activating the free spin round), more wild symbols start to appear on reels, increasing your winning chances. These wilds can also be sticky, expanding, or stacked.
Most of the Netent slots offer this feature. After scoring a win, all symbols that are part of that combination disappear from the reels and new ones appear in their places, without making a new spin. If these new symbols also create a winning combination, the process repeats itself.
These are free online penny slots with bonus rounds with two screens. You start playing on the screen below and after reaching a certain win amount, you continue playing on the screen above. Symbols on the upper screen pay more.
These are free online slots for fun with bonus that ask you to play an actual mini-game that is generally compatible with their themes. These games can be surprisingly advanced. For example, 3D slots may ask you to play an FPS game. Or, you can play a platform game as good as Super Mario - the options are endless. The prize you get is determined by how far you progress in the game. In the Captain America slot when you trigger the progressive jackpot feature a mini-game will start that asks you to match different jackpot symbols.

Playing free slots online with bonus games on mobile


As long as they are developed after 2010, you can play free online slots with bonus on mobile. It is even possible to say that the most popular slots are on mobile today.

The reason we say 2010 is that almost all developers switched to HTML5 technology after this year. This technology allows free online slots with bonus no download or registration to work on browsers and is therefore compatible with all platforms (iOS, Android, etc.).

For the same reason, it is not necessary to install an app to play such mobile slots. Prior to 2010, developers were still using Flash technology.

Games developed with Flash are not compatible with iOS devices and cannot be played on them. You can only play this kind of free online slots with bonus on Android devices.

Tips and tricks for playing new free slots bonus games


  1. Progressive slots will not usually be a good choice. These types of games also have bonus features, but their main feature is the jackpot they have. Due to this jackpot, they pay less frequently than regular slots, and their bonus features are not triggered so often. In short, if you want to play free slots online no download with bonus, don’t opt ​​for those with a progressive jackpot.
  2. If the bonus itself is a multiplier or you can win multiplier prizes during the bonus round, be sure to play with the maximum coin (bet) amount. In this way, you can unlock the highest possible payouts.
  3. You can buy the features of most of the new generation free online slots no download with bonus rounds. So, for example, you can start the free spin round at any time by purchasing it with real money. Sometimes it can be much more advantageous to do this, especially if there are multiplier payouts during the bonus round. We recommend you to decide according to the variance of the game you are playing.
  4. Choose games with at least 95% RTP to increase the frequency of winning and triggering the bonus round. For example, Playboy slots have RTP percentages ranging from 92% to 96%, and choosing those with higher values ​​will make you earn more in the long run.
