What Are Slots With Bonus Rounds?

slots with bonus rounds If you're looking for more than just a classic 3×3 reel slot, you've come to the right place. Bonus games in online slots are special features that can be activated from the base game. This usually happens when you have several specific symbols, such as scatters. Otherwise, they can randomly trigger on any spin as an added bonus during slots online . You can expect to win some of the game's biggest wins during a bonus feature. Sometimes you can even unlock a special jackpot game for a shot at the slot's top prize.

Bonus rounds work in two ways. They are either played on top of the slot's base game, possibly with extra reels, special symbols, sticky wilds or multipliers in action. On the other hand, a whole new set of reels or different game configuration can be loaded when the feature is triggered. This depends on the slot and it adds an exciting new dimension to the game.

List of the top 10 slots with bonus rounds

  1. Avalon II (amazing variety of bonuses)
  2. Game of Thrones (choice of free spins round and coin flip)
  3. The Invisible Man (best wilds slot bonus)
  4. Pharaoh's Fortune (exciting two-part bonus game)
  5. Jurassic Park (top bonus game with five random features)
  6. Rocky (unique free spin bonus)
  7. Gladiator Jackpot (exciting online progressive jackpot)
  8. Hot as Hades (free spins with different stages)
  9. Pink Panther (unique bonus game and highest progressive jackpot)
  10. Family Guy (1000x multiplier on your winnings)

How Do Slots with Bonus Games Work?

One of the best things about slots bonus rounds is that they don't take anything from your casino balance. When triggered, the bonus round will load, but any spins that take place during these rounds will not cost you a penny.

Another fantastic benefit is that even though bonus rounds are free to play, the winnings you get from them are 100% real. This makes triggering a bonus game within a slot quite a lucrative affair. Of course you still need a bit of luck to get those big wins!

Below you can see how this works in practice:

  • Get the required scatters or bonus symbols in the base game.
  • The bonus round is triggered with extra reels, free spins or a completely different game screen.
  • Play the bonus game using the free spins given.
  • Winnings from the bonus round are added and added directly to your real money balance

Activate The Bonus Round In Slots

Before you can enjoy the bonus rounds in slot games, you have to activate them first. To achieve this you usually need to get specific symbols in the slot's base game to unlock the special bonus rounds. These are commonly known as 'scatters' or 'bonus symbols'.

The exact appearance and style of the bonus symbols vary from game to game, but they often have the word 'scatter' or 'bonus' written over them. They can also be represented by the logo or main character of the slot. They are designed to stand out and will usually be distinctive compared to the regular symbols.

How Many Bonus Symbols Are Needed In Bonus Rounds?

Most slots require you to have 3 or more to get into the bonus round. You can even get different rewards depending on how many you see appear. For example, 3, 4 or 5 scatter symbols can give you 8, 15 or 20 free spins to use in that slot's bonus game.

The good news is that you usually don't need to land these symbols on an active payline to trigger the feature. They can appear anywhere on any reel, but they may also need to land on adjacent reels of the leftmost one first.

Randomly Triggered Bonus rounds

Some slot games like to give you a helping hand by randomly triggering a bonus feature on every round. Sometimes, but not always, it activates during a non-winning round. That way, the feature gives you a second chance to win without having to wager any extra money.

A random bonus round is often awarded by a slot's main character, such as Finn (in Finn's Golden Tavern). They jump into action and help trigger an event, such as a free respin. Or, they can land extra symbols on the reels. These random triggers are awesome! That's because they increase your chances of winning in the base game without taking anything from your bankroll!

Retriggering Bonus Rounds

Some slot machines have the option to retrigger the bonus round. This means that you can see specific symbols appearing during the bonus feature which will trigger the feature again. A good example of this is getting another 3 scatters in a free spins round to earn another 10 free spins. By retriggering, you can make the feature last longer.

Retriggers are a great way to increase your winning potential from a slot's bonus round without putting any strain on your bankroll. Unfortunately, not all slots have this option. Most slots require you to go back to the base game and land another set of scatters or bonus symbols to retrigger the feature.

Types Of Slots With Bonus Rounds

There are many different types of bonus games in online slots . These unique features make the games feel fresh as game developers keep coming up with new ideas. Here are a few of the most common bonus game types you can expect to find in slot games at the most popular online casinos:

Free Spins

Free spins are normally played on the same reels as the base game, but with additional features kicking into action. These can include multipliers or sticky wilds. The ever-popular Immortal Romance has a fantastic progressive free spins round for players to enjoy. The more often you activate these, the greater the rewards, which is of course a nice addition.

Jackpot Bonus

A jackpot bonus is a special bonus round where you have a chance to win the main prize of the game. Slots can have a single jackpot or multiple jackpots, such as the mini, midi and mega jackpots in the mighty Hall of Gods of online casino NetEnt . Jackpots can be fixed amount or progressive.

With a fixed jackpot you can win a multiple of your bet (up to 10,000x, 20,000x or more!). With a progressive jackpot , the prize increases with each round of the base game of each player's slot in the network. Progressive pots can run into the millions!

Choose A Reward

This gives you a blind chance to win by selecting the symbols you think hide a reward. It is common for treasure chests or playing cards to be used to hide the potential prizes. Pick the right one to get a reward, pick the wrong one and the round is usually over, and it's back to the base game. Beat the House is a good example of this style of bonus round where you have to move through the progressive levels collecting coins and multipliers of 2x.

Bonus wheel

Sometimes triggering the bonus round will take you to a wheel that you must first spin to determine your reward. There may be instant cash prizes on offer or some free spins to play. Wherever the wheel stops, that's the reward you get. The Bonus Twister Wheel in From Dusk Till Dawn is a good example of this type of bonus round.

Bonus game

Some bonus rounds appear as a completely separate feature from the slot's base game. This is, as it were, a game within a game. A new set of reels, bonus wheel or game board will appear on the screen, ready to play. The Car Chase Bonus in Cops and Robbers from Play'n GO is a good example of such a bonus round in action.
