What Are Bonus Game Slots?

Find best online slots with free games

Online slots bonus games or features are mini-games within the slot itself. Often triggered by hitting a selection of symbols (typically three scatter symbols, or a pair or more of other symbols), these games give online slots fans another fantastic chance to win.

Bonus games will usually be triggered by hitting a certain number of special symbols, often bonus or scatter ones. Sometimes, though, they can be triggered at random! There are a few different types:

There are also many other types of bonus features, as the world of online casino games is ever-growing and more and more good ideas are brought forward. Not every online slot machine has a bonus game, and some that don't feature one will make up for it by having a very high chance of winning during regular spins.

What Makes A Good Game?

Because bonus game slots are some of the most popular in the world, the best online casinos will offer a selection of bonus game slots – often hundreds!

It can be hard for online slots players to choose the right bonus game slot to play online, but to make it easier we focus our reviews on a few factors:

  • The Chance of Playing - If you play a slot online then it might have the best bonus game in the world, but if you can only play it once every 50,000 spins then it isn't much good! The best online slots have bonus games that occur frequently.
  • The Top Prize - A bonus slots game may come up very often, but it might only double your prize. On the other hand, a rare game may offer prizes up to 10,000x your bet – we look at all the factors and weigh them up to pick the best.
  • The Fun Factor - Besides the money, one big reason that online slots have bonus games is to make the game fun. A boring game is a bad game!

Are Bonus Came Slots Better Than Regular Slots?

Some online slots don't have any bonus games at all. Sometimes this is because they are classic slots, emulating one-armed bandits and keeping things simple and stripped-down, and other times it's because they offer a high chance of winning without a bonus.

However, all of the world's most popular online slots will feature one or more bonus games. Players love bonus games and feature rounds, so our most recommended games almost always have fantastic ones.

If you have further questions about bonus game slots, hopefully we can answer them.

Which games have the best bonus rounds?
Games like California Gold have the best bonus rounds that balance frequency, winning, and fun. The best bonus games will always give you a good chance of triggering them, have a high jackpot prize or top prize, and be fun to play!
Can I win more by playing bonus game slots?
Definitely – the best bonus games offer the chance to win huge prizes. Generally, games without features are what are known as low variance games, paying out regularly but with little chance of ever getting huge prizes. On the other hand, bonus-filled games will give you the opportunity to win life-changing money.
Can I try out bonus game slots for free first?
Most of the best online casinos will let you play free versions of online slots, complete with a full bonus game. This will allow you to get a feel for the games and see which one you prefer, though remember that you won't be able to win real money.
How do I get to the bonus game?
This depends on the slot, but it usually requires you to hit a series of special symbols during a spin. You can consult each game's paytable or ask the online casino to find out more. As mentioned in the above question, free slot games with bonus rounds are available too.
Are bonus games fixed?
When online slots and online casinos tell you your chance of winning, the bonus game is included in that average. They are legally obligated to give correct odds and percentages.
