Game Rules

Penguin Vacation

5-Reel, 20-Line SlotFishing Bonus Begins with 8 Free Games and X2 Multiplier!

The objective of playing Penguin Vacation slot is to land a winning combination of symbols on the reels. The slots also features a Free Games Bonus that can help boost your winnings. Fans of online blackjack are also sure to love the Gamble Feature, where you can double your winnings on the turn of a card.

How to Play:

  • Open the Click To Change Menu to choose a coin value for the Line Bet.
  • Click Bet Per Line to add a coin to the Line Bet. Each click will add another coin, up to a maximum of 10.
  • Press Lines to activate up to 20 paylines. You can also choose paylines by clicking on the numbers 1-20 on the sides of the reels. Please be aware that choosing a number will also activate paylines numerically below it.

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

  • Click Spin or Bet Max to spin the reels. Spin will play at the current Line Bet and number of paylines. Bet Max will spin the reels with 10 coins placed on the Line Bet and all 20 paylines activated.
  • Use the +/- button either side of the Auto Start Field if you want to set a specific number of spins to be played automatically. Press Auto Start to begin. This button will change to Stop when Auto Start Mode is on – select it if you wish to exit Auto Start Mode.

Note: A winning combination will be highlighted on the reels after a spin. The total win (if any) will be shown in the Win Field. A winning spin will also activate the Gamble Feature. This will be explained further in a section below.

Note: All payouts for the game are displayed on the Paytable, which can be accessed via the Info button. Line Wins = Payout x Line Bet. Scatter Wins = Payout x Total Bet.

Info Pages:

Click Info to access the Penguin Vacation 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 page. Press Back to exit and return to the main screen. The Info Pages are as follows:

Paytable – shows all possible payouts for Line Wins and Scatter Wins. Press Show Paylines on the bottom of the screen to load a display showing the positions of all 20 paylines on the reels.

Fishing Bonus – describes the rules and special features of Fishing Bonus/Free Games.

Gamble – explains the rules of the Gamble Feature. It also displays the maximum double up limit.


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

There is a clear 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, i.e. Line Bet x Number of Paylines.

About Payouts:

All possible payouts for Penguin Vacation are displayed on the Paytable. Line Win payouts are multiplied by the Line Bet. Scatter Win payouts are multiplied by the Total Bet.

Only the highest value Line Win is paid on each payline. Multiple Line Wins (on different paylines) are added together and paid out as a total win.

A Line Win must start on Reel 1, moving left to right across the reels in a chain of symbols on an active payline.

Wild Symbol:

The Wild Symbol can substitute for any other symbol (except Scatter) to make the best possible winning combination on a payline. A Wild Symbol will double the payout of any Line Win that it substitutes in.

The Wild Symbol appears stacked across all reels. This means that it can cover all positions on that reel.

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

Scatter Symbol:

The Scatter Symbols do not need to fall on any paylines to pay out. Two or more Scatter Symbols in any position on the reels will award a payout (x Total Bet).

Three or more Scatter Symbols in any position will award the Fishing Pool Bonus.

Fishing Bonus:

Press Click To Start to begin the Fishing Bonus. A new screen is launched. You will initially be awarded 8 Free Games with a x2 Multiplier.

You must choose two pools for the penguins to fish in. Fishing in the pools will reveal extra Free Games and/or Multipliers.  These will be added to the initial 8 Free Games and x2 Multiplier.

The Free Games will play through automatically after the Fishing Bonus ends. The remaining Free Games and the current Multiplier are displayed on the top left of the screen. The total win for Free Games is shown on the top right of the screen.

Any Line Win or Scatter Win payouts awarded during Free Games will be multiplied by the Multiplier gained in the Fishing Bonus.

When all Free Games have been played through, a results screen will appear detailing the total win from Free Games (Feature Win) and the triggering spin (Game Win).

Please note:

  • Free Games are played at the same Line Bet and number of paylines that triggered the Fishing Bonus.
  • 15 extra Free Games are added if three or more Scatter Symbols fall anywhere on the reels. The Multiplier will remain the same.


Any win in the main game will activate the Gamble Feature, as long as it does not exceed the maximum double up limit.

Press the Gamble button to begin. A new screen will be opened. The aim of the feature is to guess whether the next card drawn from a deck will be red (diamonds, hearts) or black (clubs, spades).

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

If you guess correctly, you can keep doubling up until the maximum double up limit has been reached.

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

Please Note:

  • The Gamble Feature is not available during Free Games or when you are playing in Auto Start Mode.
  • Information on the double up limit is displayed on the Gamble Info Page.
