To activate the Free Spins Feature in ‘Book of Golden Sands’ online slot, you'll need to land a few Scatter Symbols; three or more to be specific. These symbols look like a giant book with a pink jewel on the cover. They can appear on all reels and when the round begins you will start off with 10 free spins. As you continue to play, you should start to look out for the Special Expanding Symbol. This is a regular symbol, selected at the start of the Free Spins Round, to act as a special Symbol. Its job is to expand vertically to cover all the positions on its reel; therefore, creating extra chances to land a matching combination. If you don't hit the first time, don't worry! You can now always retrigger the feature by landing an additional three or more Scatter Symbols. If you manage to achieve this, your free spin tally will be topped back up to ten free spins. On top of this, you could do this multiple times as there is no limit on the amount you can retrigger this generous feature.
