What are Slots with Bonus Games?

As you’re likely aware, scooping a payout on an online slot is traditionally a matter of landing a specific number of matching symbols in sequence. However, many modern-day slots also include a number of special features that you can trigger via the base game, whether it be randomly or as a result of a specific outcome occurring. The best part of it is that they’re often the path to the game’s largest payouts.

The way it works is simple; you place your wager, spin the reels and if you’re lucky enough, you’ll activate a bonus. The most common way of this happening is by landing 3 or more Scatter symbols, which often results in a free spins mode where you can unlock additional benefits such as multipliers, extra wilds and other such mechanics that vastly improve your chances of winning. However, certain slot games also introduce random features that can trigger on any spin, which only adds to the excitement and anticipation.

The Different Types of Slots With Bonus Games

Innovation is obviously key to keeping things fresh within the world of online slots. Although some players still enjoy spinning on classic slots, many others prefer to test out the latest features and mechanics. As such, casino game developers are constantly coming up with new ways to keep you interested in playing and hunting for those massive wins. Below, we’ve outlined some of the most common and rewarding bonus games you can expect to trigger.


Free Spins

These often utilise the slot’s standard paytable but introduce additional features to improve your chances of winning. You’ll often receive special multipliers that increase the value of any given win, thus unlocking the game’s true payout potential. However, other benefits can include Sticky Wilds, Expanding Symbols, Mystery Symbols, upgraded symbol values and much, much more. So, be sure to check what a particular slot offers within its free spins mode beforehand to fully understand what’s going on.



These are sometimes awarded as a sort of compensation for not quite fulfilling a game’s bonus trigger requirements. You might get an extra shot at activating the main feature, or you may earn another spin that benefits from certain upgrades.


Jackpot Bonus

Jackpot bonuses can offer you a shot at the game’s top prize. These can either trigger randomly or be part of another feature, thus adding another dimension to your experience. Some slots introduce multiple fixed jackpot prizes, commonly in mini, minor, major and mega forms, whilst others utilise huge progressive jackpots that can offer payouts in the millions.


Pick a Reward

Here, various prizes are often hidden behind special symbols. All you need to do is pick random symbols to reveal your reward(s). In some cases, it can be a progressive feature, whereby prizes will increase in value the more selections you successfully make. However, if you pick the wrong one, the bonus round usually comes to an end and you’ll win everything you’ve accumulated to that point.

Bonus Wheels

Certain bonus games have set rewards, whereas other slots have bonus wheels that determine your prize. There could be instant cash prizes or free spins with special modifiers on offer. Wherever the wheel comes to rest though, that’s the prize you’ll receive.


Bonus Games

Some features are entirely separate from the original base game. Think of it as a game within a game. You could come across an entirely new set of reels with unique symbols or a completely different game board – it’s entirely dependent on the game provider’s imagination. Whatever is on offer though, you can be sure that some fantastic prizes are available!

How to Choose the Best Slots with Bonus Games

Choosing the right slot isn’t always just a matter of loading something up that looks good. If you’re looking to maximise your potential returns, you’re going to want to familiarise yourself with what the bonus games have to offer. To help you do so, we’ve highlighted several tips below that will help you separate the top games from those you may be better avoiding.

1Check the paytable

All slots have a paytable that details the value of each symbol. It also includes information about the game’s key features, how to trigger them and how they can generate huge payouts. It’s a great way to immediately identify the respective payouts, along with the style of features within a given game.

2Read our slot reviews

Perhaps your best initial course of action is to check out our in-depth online slot reviews. Our team of experts analyses every aspect of a new slot, concisely outlining what’s on offer. We then compile an honest breakdown of its features and its payout potential so you can gauge whether it’s the right fit for you before playing for real money.

3Play for free in demo mode

You can also use demo play to our advantage. Many online casinos let you try out their slots for free using virtual credits to get to grips with the features and mechanics. It’s a great way to figure out if a game suits your particular preferences.

4Measure RTP & volatility

RTP (Return to Player) and volatility impact how the slot’s gameplay theoretically unfolds. As such, choosing games with a higher RTP rate and low volatility is often the best way to gain access to certain bonus rounds. Of course, it’s not a guarantee, but the longer you sustain your bankroll, the more spins you can play, thus giving you a greater chance of triggering special in-game features.
