One of the most popular features found in slots is a bonus round.

What Are Bonus Rounds In Slots?
Not all slots have a bonus round feature, but most do unless it is a classic slot.
Starburst is one example.
The slot does not have a bonus round but is still a popular game in the slot community.
Typically, a slot will offer a bonus round with ten free spins, but sometimes, the total can increase to 30, 50, or even 100.
Bonus rounds can also include multipliers, extra wilds, or expanding symbols. Bonus rounds offer gaming that you don’t pay for.
Once the round is triggered, you can spin at no cost and earn wins or other incentives.
How To Get Bonus Rounds On Slots
A bonus round is typically triggered with three or more scatter symbols somewhere on the reels.
There may be a collection meter, such as the case with Finn and The Swirly Spin slot.
Easily see how to activate the bonus round by reviewing the info section of a slot game.
Bonus Rounds vs. Free Spins
Bonus rounds and free spins are typically the same thing, but sometimes they are different.
Many slot games offer a bonus round where you trigger free spins from scatter icons.
Others may have bonus rounds where you play mini-games or activate jackpot rounds with bonus icons.
You can see how a bonus acts by reviewing the information section of a slot you wish to play.
An example of a varying bonus round can be found in Cops ‘n Robbers by Play’n GO.
The game has a bonus round where a car chase takes place.
You also earn free spins, but an interactive element enhances the round.
