The WILD symbol substitutes for all symbols except the MONET and CARD symbols.
When a 1×4 partial wild symbol appears, it is pushed up or down to cover the entire reel.
Each coin can activate a bonus round on an idol that matches the colour of the coin symbol.
The Card symbol during the Hold and Re-spin bonus round brings between 10 and 500.
RED Coin, BLUE Coin and PHYOLETIC Coin are Coin symbols. One or more MONET symbols can activate the Hold and Re-spin bonus round. 3 re-spins are awarded. The Hold and Re-spin bonus round starts with empty reels. During the ‘Hold and Re-spin’ bonus round, only the CARDS and activating MONETS corresponding to the active bonus rounds appear. All CARDS and MONETS are held and other positions are re-spun. If another CARD or MONET appears, the number of re-spins is restored to 3. The prizes for a CARD can be as follows 10, 20, 50, 70, 100, 120, 250 or 500 credits. Re-spins will end if there are 0 re-spins remaining or all positions on the reels are filled with CARD and/or MONET symbols. All CARD and MONET values are paid when the re-spins are completed. If all positions are filled with symbols, an additional prize of 250x is won and the Hold and Re-spin bonus round ends. PHYOLETOUS and RED MONETS have no effect on other PHYOLETOUS and RED MONETS that are rolled in the same spin.
The PHYOLETOUS MONET is a bonus round of improvement. Once dropped, it improves each surrounding held prize by 5, 10 or 20 and unlocks its prize. After improvements, she will unlock her prize. Prizes for PHYOLETIC MONETS can be as follows 10, 20, 50, 70, 70, 100, 120, 250 or 500 credits. PHYOLETIC MONETS only enhance surrounding symbols that have already unlocked a prize. ‘Surrounding symbols’ are symbols located 1 position to the left, right, above, below and diagonally from the specified symbol (up to 8 positions in total).
The BLUE Coin is the bonus ‘Big Prize’. Possible prizes are 150, 200, 300, 400 or 500 credits.
The RED MONET is the Hoarder bonus round. When it falls, it will collect all held prizes. If more than one RED MONET falls in one spin, they will collect equal amounts and will not collect each other’s prize.
