Siren’s Spell Bonuses and Special Features
Siren’s Spell includes several special features that add excitement to every spin. Wilds, represented by sirens, substitute for regular symbols and expand to cover the entire reel when they land.
The Free Spins feature activates when three Pearl Scatters appear, awarding 15 free spins and introducing symbol upgrades. As players collect winning combinations, Medusa symbols can be upgraded for higher payouts. Each full upgrade grants an additional 15 free spins, extending the bonus round.
The Super Bet feature allows players to double their bet for increased chances of landing Wilds and Scatters.

Siren’s Spell Free Spins
The Free Spins feature activates when three Pearl Scatters land on the reels in a single spin, awarding 15 free spins. During this round, winning combinations contribute to symbol upgrades, gradually transforming high-value symbols into Medusas, which offer the highest payouts.
Each time a full upgrade is achieved, 15 additional free spins are awarded, extending the bonus round and increasing potential rewards. With no set limit on retriggers, players can continue upgrading symbols and accumulating more free spins.
Buy Feature
For players who don’t want to wait for three Pearl Scatters to trigger free spins naturally, Siren’s Spell offers a Buy Feature. This option allows instant access to the Free Spins round for 50.08x the current bet.
Once purchased, the game immediately triggers the 15 free spins, with all the standard symbol upgrade mechanics in place. This feature is ideal for those looking to jump straight into the action without relying on base game spins.
Siren’s Spell Tips for Winning
Winning in Siren’s Spell is based on luck, as all outcomes are random. To make the most of your gameplay, consider setting a budget and sticking to it. The Super Bet feature can increase the chances of landing Wilds and Scatters, but it also raises the stake, so use it wisely.
