How to Play:

  • Click Bet Per Line to add a coin to the Line Bet. Each click will add another coin, up to a maximum of 10 coins.
  • Click Lines to activate up to 25 paylines. You can also choose paylines by clicking on one of the numbers 1-25 on the sides of the reels. Please be aware that choosing a number will also activate all paylines numerically below it.

Note: The Total Bet = Line Bet x Number of Paylines.

  • Press Spin or Bet Max when you have selected your bets. Spin will spin the reels at the current Line Bet and number of paylines activated. Bet Max will spin the reels with the maximum of 25 paylines activated and the maximum Line Bet (10 coins).
  • Use the +/- buttons above the Auto Start button to choose a specific number of spins to be played automatically. Press Auto Start to begin. When Auto Start is on, the Auto Start button will change to Stop, press it to turn off Auto Start.

Note: A winning combination will be clearly highlighted on the reels.

Note: All payouts are displayed on the Paytable, which can be accessed by clicking the Info button. Line Win = Payout x Line Bet. Scatter Win = Payout x Total Bet.

Note: A winning spin will activate the Double Feature. This will be explained in detail in a section below.

Info Pages:

Press the Info button to launch the Info Pages, which includes the Paytable and information on the Bonus Features. You can move through the different pages using the arrows on the bottom right of the screen. Press Back to exit and return to the reels. The Info Pages are shown below:

Paytable – displays the payouts for all winning combinations in the main game. You can press the Show Paylines button at the bottom of the Paytable screen to load a graphic showing the positions of all 25 paylines.

Knockout Bonus – describes the rules and awarding of the Knockout Bonus.

Free Games – describes the rules and special features of Free Games.

Rocky Feature – describes the special payout for the Rocky Feature.

Double Feature – explains the rules of the Double Feature.


Paylines are the directions that matching symbols must follow across the reels to pay out as Line Wins. Only active paylines (the ones that you bet on) can record Line Wins.

Please note that there is a difference between the Line Bet and the Total Bet. The Line Bet is the amount staked on each payline. The Total Bet is the amount staked on all paylines (added together).

About Payouts:

All possible payouts are listed on the Paytable. Line Wins are calculated x Line Bet and Scatter Wins x the Total Bet.

Only the highest winning combination is paid on each payline. Multiple wins are added together and paid out as a total win.

A Line Win must begin on Reel 1, moving left to right across the reels in a chain of matching symbols.

Wild Symbol:

The Wild Symbol can substitute for all other standard symbols to help form the best possible Line Win on a payline. The Wild Symbol cannot substitute for the Bonus and Free Games Symbols.

Wild Symbols can also form their own Line Wins with a separate payout.

Scatter Symbol:

Scatter Symbols do not need to fall on any paylines to be active in the game. Two or more Scatter Symbols falling in any position on the reels will award a payout (x Total Bet). Three or more Scatter Symbols in any position will award Free Games.

Bonus Symbol:

The Bonus Symbol appears on Reels 1 and 5 only. It does not have any payout value. Instead, you will be awarded the Knockout Bonus if two Bonus Symbols land anywhere on these reels simultaneously.

Rocky Feature:

If the R, O, C, K and Y Symbols appear in consecutive order on the reels, spelling out R-O-C-K-Y, you will earn a payout of 5 x the Total Bet. The symbols (in this situation only) act as scatters, so R can appear anywhere on Reel 1, O can appear anywhere on Reel 2 and so on.

Knockout Bonus:

The Knockout Bonus is awarded when a Bonus Symbol lands on Reel 1 and 5. Press Click to Start to begin the Knockout Bonus.

A new screen is launched, where you will be prompted to choose an opponent for Rocky to fight. The fight will go across 10 rounds. You will earn a payout of 3 x the Total Bet (of the triggering spin) for each round that Rocky wins.

Rocky is guaranteed to win the fight in one of the rounds via knockout. If Rocky knocks out his opponent earlier than the 10th round, all subsequent rounds are deemed to have been won by Rocky and you will be paid accordingly.

Please Note:

  • The Knockout Bonus cannot be awarded during Free Games.
  • The Knockout Bonus and Free Games can be awarded in the same spin, the Knockout Bonus will be played first when this occurs.
  • When the Knockout Bonus has finished, a summary screen will appear detailing the total win from the feature.

Free Games:

Free Games are awarded when you land three or more Scatter Symbols in any position on the reels. Press Click to Start, which will load an Info Screen explaining that you have won 15 Free Games with all wins doubled. Press Continue to begin Free Games.

The Free Games will play through automatically. All Line Wins and Scatter Wins will be doubled for the duration of the feature. 15 more Free Games are added if you land three or more Scatter Symbols in the same manner as the triggering spin. The Multiplier remains at x2.

Please note:

  • Free Games are played at the same Line Bet and number of paylines as the triggering spin.
  • The Knockout Bonus is not available during Free Games.
  • Extra Wild Symbols are added to the reels during Free Games.

When all Free Games have been played through, a summary screen will appear detailing the total win from Free Games and the triggering spin. Press Continue to return to the main game.

Double Feature:

A winning spin in the main game will activate the Double Feature. Press the Double button if you wish to enter the Feature. The objective of the Double Feature is to guess if the next card drawn from a deck will be red or black.

  • A correct guess will double your winnings.
  • An incorrect guess will forfeit your winnings.

If successful, you can keep doubling up your winnings until the maximum double limit has been reached. This information will be displayed in the Double Feature Info Page.

Press Collect at any time to bank your winnings and exit the Double Feature.

Please note:

  • The Double Feature is deactivated during Free Games and when the slot is played in Auto Start Mode.
  • The top of the screen will display the results for previous rounds of the Double Feature.
