Book of Sun: Choice

When three or more Book symbols land during the main game, they unlock a set of 12 Free Spins. If additional Books appear while the feature is already active, they add another 12 spins to the round, giving players more chances to extend the session and build larger wins without restarting the base game.

At the start of the Free Spins feature, players must select one symbol to act as a Special Expanding Symbol for the duration of the round. Each time the feature is retriggered, an extra expanding symbol can be chosen, with the potential to fill reels and create bigger wins as the bonus progresses.

During Free Spins, players can activate up to nine Special Expanding Symbols. Any symbol from the paytable, except the Book, may be chosen for this role. When selected, it has the ability to expand and fill the entire reel, adding a dramatic boost to the round.

If more than one Special Expanding Symbol is active, they expand one after another whenever enough symbols land to create a win. Expanded combinations pay even when symbols are not on adjacent reels, ensuring more frequent payouts and enhancing the overall winning potential.

The game includes an option to instantly purchase Free Spins instead of waiting for them to trigger naturally. The cost of buying the feature is 90× the current bet, and once purchased, the Free Spins begin immediately at the same stake level. Players should note that the option is unavailable if there is not enough balance. This feature provides a shortcut to the most exciting part of the gameplay, letting players dive straight into the Free Spins round with the chance to unlock Special Expanding Symbols.
