Symbols and Paytable
Symbols in the game reflect traditional Chinese motifs and classic card values. The lower-paying icons include 10, J, Q, K, and A, while higher-paying symbols feature the jade ring, red envelope, golden dragon, and Cai Shen himself as the premium icon. The Book symbol functions as both Wild and Scatter, playing a dual role by substituting for other symbols and triggering special features.
Free Spins Feature and Special Mechanics
Landing three or more Book symbols activates the Free Spins bonus, granting 10 free spins and a rewarding scatter payout of up to 200× your stake for five symbols. At the start of the free spins, a special expanding symbol is randomly chosen from the reels.
Players typically have a chance to reject the first symbol and opt for a second, adding strategic depth to the bonus. When the expanding symbol appears during free spins, it fills entire reels—even on non-adjacent positions—greatly boosting the winning potential.
Golden Book Wild Symbol
Exclusive to the free spins round, the Golden Book symbol serves as a powerful Wild. When it lands, it transforms the entire reel into gold and can expand to complete winning combinations, enhancing payout opportunities.
Ultra Bet Bonus Option
The Ultra Bet feature allows ambitious players to enhance their gameplay. By paying 50× your stake, players unlock 50 enhanced spins where special stars appear on symbols. Collecting enough stars during these spins can trigger multiplier prizes and bonus rounds—offering accelerated access to wins and bonus features.
