One of the first things many players look for in a new slot is a free spins bonus. It's easy to see why when you consider that you can be awarded a huge number of free spins just for landing a set of symbols on the previous spin. Who doesn't love to spin the reels without risking their own money?
That's not all though. The popularity of free spins isn't just down to the risk-free nature of the bonus. Most games offer increased payouts to wins made during the free spins round. This means that they are an easy way to boost your balance.
In most slots the free spins feature will be activated when you land three or more of the scatter or bonus symbols on the reels. Some games will reward you with the same number of free spins no matter how many symbols triggered the feature while others will award further free spins for each extra symbol used. Other slots will award free spins as a prize in a different bonus game.
In many slots you'll find that free spins can be retriggered. This means that by landing three or more scatters or bonus symbols again you are allocated more free spins. In theory this could go on indefinitely but this is rare and most slots are designed to offer a maximum number of free spins in any one round. Other games do not offer the chance to retrigger free spins and you'll only receive the number allocated at the beginning of the bonus feature.
The vast majority of slots will take your last wager as the stake for free spins. So if you've only bet on one payline when you activate the free spins, that's what will happen during the free spins round. This means that the higher your wager in the base game, the bigger your wins will be during the free spins bonus.
