Book of Sirens The Golden Era Slot Game Overview

Book of Sirens The Golden Era is a sequel to the Book of Sirens slot. The mythical underwater-themed slot game features 5 reels, 3 rows, and 10 paylines. It also has bet options ranging from £0.20 to £10 per spin.

The slot is set in a tumbling blue sea with a backdrop revealing light rays from the sky travelling into the blue water. Golden frames surround the dark game reels. 

Several low and high-paying symbols feature in the Book of Sirens The Golden Era slot. The low-paying symbols are the traditional playing cards A, K, Q, J, and 10. The high-paying symbols are two sirens and two sea monsters. 

Landing 5 identical low-value symbols on a payline could award up to 15x your wager. If you land 5-of-a-kind high-value symbols on a payline, you could earn up to 500x your wager.

The book acts as both the wild and scatter symbol and can replace any other symbols on the reels.

Extra Spins Feature

The Extra Spins feature is triggered if you land at least 3 scattered wilds anywhere on the reels. Landing 3, 4 or 5 scattered wilds awards a 2x, 25x, or 250x your stake payout, respectively. It also awards 10 Extra Spins. 

If you retrigger this round, you could get an extra 10 Extra Spins. 

Extra Spins – Expanding Symbol

Upon activating the Extra Spins feature, a wheel containing all symbols except the scattered wild appears. You get to spin the wheel to determine which symbol becomes the expanding symbol for the duration of the bonus round. 

The selected symbol may expand to fill the reel and form new paylines, but only if the expansion results in a winning combo forming.

Return To Player

Return to Player (RTP): 96.06%

RTP is used to explain the potential money that an online slot or casino game can pay back to players. It appears as a percentage and is generally calculated from gameplay over a long duration of time.

For example, if a slot has a RTP of 97% this means that it could pay back £97 for every £100 wagered.

However, there is no guarantee that players will receive this amount, as slot payouts are entirely random.
