Bonus functions and unique mechanics

• Free Spins (10 free spins): activated on landing 3 or more Book symbols (Scatter/Wild). Before the start of the round, the player selects one of the regular symbols, which becomes a special expanding symbol.
• Expanding symbol: during free spins, the selected symbol can appear on any reel and expand to the full height, forming winning combinations regardless of position.
• Book symbol: fulfills the role of Wild and Scatter simultaneously — substitutes for other symbols and triggers the bonus.
• Ultra Bet option (in some casinos): allows increasing the chances of activating the bonus at the cost of raising the bet.

Unlike some analogs, the selection of the expanding symbol is made by the player, not the system — this gives more control over the strategy.
