Classical slots are mostly thrilling and fun. However, if you are looking to step up the action, then you have come to the right place. Bonus rounds on some of the best online slots could transform your experience on the reels more than you could ever imagine. 

You can attain new heights with your favourite slots by exploring the interesting features that come with the bonus rounds. Finally, you could find yourself at the brink of massive payouts on the highest RTP slots. All these give you more than enough reasons to want to understand everything about bonus rounds in slots.

What are Bonus Rounds in Slots?

Bonus games are unique features in online slots that can be unlocked from the main game. This usually occurs when multiple special symbols like scatters, appear on the screen. They may also come randomly as an extra bonus in slot games. This could be at any time and on any spin.

Bonus rounds give you a better chance of winning the game’s highest prizes. More so, you could be eligible for a special jackpot game, which could earn you a top prize at the slot. You could either play bonus rounds on the slot’s base game with the other features or separately on its own.

How do They Work?

Perhaps, one of the most exciting things about bonus rounds is that they do not affect your bankroll. This means free spins for you when you trigger your bonus round. More interestingly, you get complete and 100% real wins from your bonus round play. These reasons make triggering your bonus round more than a worthy idea even though you would need a fair size of luck to win big on the reels.

Here’s how bonus rounds work:

  1. Get the required bonus symbols or scatters in the base game

  2. The bonus could trigger extra reels, free spins, or a completely different game screen

  3. Play the bonus game with the free spins given

  4. Your wins from the bonus round are added up and paid to your real money account

How to Trigger Bonus Rounds?

To start enjoying the benefits of your bonus rounds, you have to trigger them by landing special symbols known as scatters or bonus symbols. Unlocking your bonus varies from slot to slot. For some, you might need to land 3 or more scatters while others allow random triggering and retriggering to give you a second shot at winning.

With tons of UK bonus rounds available, it could be hard to determine what is best for you. Below are a few things to bear in mind when finding a slot with a good bonus round: 

  • Hit frequency: This simply tells you how realistic your chances of triggering the bonus are. A good slot should have a decent hit frequency.
  • Entertainment: The bonus round should be backed by a strong theme and huge rewards to keep you entertained.
  • Payout Potential: We all need our efforts rewarded. Games should have bonus round multipliers to boost wins.

Why is a Bonus Round Important?

“Any good casino player should take advantage of bonuses thrown their way.” The best casino players follow this quote hook, line, and sinker. Bonus rounds and their different features at slots all have one thing in common – rewarding the player with extra benefits. Here are some reasons a bonus round is important:

  • More interaction: Bonus rounds give players added interaction with the gameplay at slots. With better graphics, visuals, and sound effects, players interact with the slot better than ever.
  • Potential for more money: Bonus rounds give players a better shot at increasing their bankroll by hitting the right winning combos. Some even go as far as offering guaranteed prizes.
  • More entertainment: Bonus rounds add more fun elements to the base game at slots. If you are looking for more action on your favourite slots, bonus rounds are a great option for you.

NetEnt produced this low-volatility game with colourful symbols and huge prizes. Although it only has one bonus feature, its small and consistent rewards make it more desirable.
