Best No-Download Slot Games With Bonus Rounds

When slot games were first launched, they generally consisted of classic 3x3 fruit machine slots that people could only play in land-based casinos. However, if you fast-forward to today, you’ll probably realise that slot games have come a long way!

Not only can developers incorporate numerous storylines and themes into their games, but they can also add additional paylines and reels. For example, nowadays, you can play fruit, action, mystery, travel, animal, or racing-themed slots, to mention a few. 

In addition, online slots could offer 3 paylines, 5 paylines, 100 paylines, and up to millions of ways to potentially win. However, the best part is that most modern slots offer plenty of bonus rounds. So, what are the best no-download slot games with bonus rounds? Let’s find out in this Wizard Slots blog post below.

What Are Bonus Rounds On Slot Games?

Usually, bonus rounds can fall into two categories; free spins and in-game features that match the slot’s theme. They typically require a specific symbol combination or action to occur before you can play them. If activated, players can access a special extra, like X number of free games to play during a free spins feature.

Note that, depending on the slot game, some bonus rounds or modifiers can occur randomly in the base game. For example, you might play a game offering a free spins round but not get a chance to sample the feature. 

However, some bonus features may be available to trigger randomly in the base game. For example, progressive jackpots can be bonus rounds, too, and in some slots, they can activate during a random base game spin.

One reason why people enjoy playing bonus rounds so much is that they have the potential to make the gameplay more entertaining. To see what bonus features a certain slot may offer, you can view the game’s paytable or rules for more detailed information.

How Do Bonus Rounds In Slots Work?

Bonus rounds can work differently depending on the game. For instance, you may unlock a feature on a random spin during the base game, or you could land a number of scatter symbols to activate a specific bonus round.

Before playing a slot, you can review the paytable to see if any bonus features are available to trigger.

A range of possible bonuses like re-spins, special symbols, pick bonus rounds, multipliers, cash prizes, and more exist. For example;

Free Spins: this bonus round can typically be unlocked by landing 3+ scatters in a single spin. You may then win X number of free spins to play in a bonus round.

Special symbols: special symbols could unlock mystery prizes.

Colossal symbols: these symbols are larger than regular symbols. For example, they can occur in 2x2, 3x3, 6x6, etc., depending on the game.

Multipliers: you can trigger various multiplier values like 2x, 3x, 4x, 10x, 20x, 100x etc.

Stacked symbols: matching symbols can land randomly stacked, and some may even fill up an entire reel!

Pick rounds: pick rounds involve clicking on a particular item on the screen to reveal a potential prize or unlock a certain bonus round.

Some bonus rounds can trigger randomly, but others might require a certain combination of symbols or action. For instance, you might need to spin a bonus wheel to win a number of free spins. The picks round is also another example of an interactive bonus.

The best part about bonus rounds is that they can occur at no extra cost to you. In addition, some bonuses can allow re-triggers. After the feature ends, the game calculates any winnings and adds them to your balance.

How To Trigger The Bonus Round Feature In Slot Games

Remember, triggering bonus round features varies depending on the slot game. However, most require special symbols like wilds or scatters to launch them. These can also be called special symbols. Sometimes, the special symbols can land in random positions or appear on specific reels.

Generally, the more scatter symbols that land, the more free spins you can win. Some online slots can even offer you another chance to try and re-trigger the feature. However, you can always view the paytable to see how any features can be triggered.

Are Bonus Rounds On Slot Machines Predetermined?

Some players think that bonus rounds on slot machines are predetermined. Remember that slots use Random Number Generators (RNGs), which compute unpredictable outcomes on each spin. Just because a game has a certain bonus feature listed in its paytable, doesn’t mean you will encounter it during play.

As we mentioned earlier, bonus features are random, so they might not always be available in an online slot. Bonus features are more of a fun addition to break the base game monotony.
