One of the most common bonus rounds that are found in online slots is the free spins round. Free spins are spins that will not cost you anything. The number of free spins that you receive will depend on the slot game that you play.
These bonus games are launched within the slot game and are not a free spin promotion
What are Bonus Games
You will usually find bonus games in almost every slot game and this bonus game is usually free spins.
The basic idea with free spin bonuses is that you are awarded a number of spins when you enter the bonus game. The number of free spins that you are awarded will vary, but between 5 and 25 free spins is common. The free spins that you receive will usually be played at the same stake level used to trigger them. You will also get to keep any money that you win during this round.
It then makes sense to bet the maximum so that your free spins are also played at the maximum and you have the potential to win more.
How Free Spins are Triggered
The most common way for free spins to be triggered is to land a certain number of scatter symbols across a payline. If you want to know how to trigger the free spins in the slot game that you are playing then take a look at the paytable.
Free Spin Extras
You can even increase your winnings during the free spins round with multipliers and wilds.
Multipliers will multiply your winnings by a certain amount and wilds can increase winnings further.
You can find standard wild symbols, sticky wilds, cascading wilds, shifting wilds, stacked wilds and expanding wilds in free spins rounds.
Retriggering the Bonus
You also have the chance to re-trigger the bonus during the round, which means you will be able to get extra free spins. Usually, to re-trigger the free spins, you will need to land more scatter symbols.
However, you are not able to continuously re-trigger the free spins, as the slot game will have a maximum number of spins that can be awarded in one round. However, there are also games that will offer no re-triggering opportunities.
Free spins are a valuable bonus round in a slot game and these slot bonuses can highly increase your winnings, so you can take home even more.
