The Game
The 9 slots game consists of a slot machine with five reels whereby your winnings is enhanced by a multiplication of a bonus round. By obtaining a winning symbol combination of the nine selected lines you achieve your aim. Depending on the number of coins you play on the online casinos, and the winning combinations displayed in the payout table determines your own payout.
All about the bonus round
The bonus round in 9 line slots begins the moment you achieve a four or five symbol combination on the neighboring reels. You are allowed to multiply your winnings in the bonus round in the following manner:
Bonus symbol value x bonus multiplier x played coins = bonus winnings round
Depending on the number of bonus symbols attained on succeeding to the bonus round determines the value of your bonus symbols. Your bonus symbols value will be equal to two if you obtained in the nine line slots any five neighboring bonus symbols. Your bonus symbols value will be equal to one if you obtained in the nine line slots four neighboring bonus symbols. At the termination of the bonus round your bonus multiplier can be determined on your online casinos. On seeing the END symbol you know the bonus round has terminated.  To determine the bonus multiplier’s total all the bonus multipliers are added up. Prior to returning to the usual 9 line slots game your total bonus winnings will be lucidly shown on the monitor.
