How to Play:

  • Select your bet for each payline by using the +/- buttons underneath the Line Bet Field.
  • Select the number of paylines you wish to play by using the +/- buttons underneath the Lines Field.
  • Total Bet = Line Bet x Number of Paylines.
  • Select Spin when you are happy with your bet selections. Select Bet Max to spin the reels instantly playing the maximum number of paylines.
  • If you wish, you can set a number (10-99) of spins to be played automatically using Auto Play. Click the Auto Play button and choose the number of Auto Spins you wish to play; these spins will only stop if you select Stop, or are awarded a Bonus Feature.
  • You can switch on Turbo Mode to speed up the reel animations for faster results.
  • When the reels have come to rest after a spin, any winning combinations will be clearly highlighted. The total win (if any) will be shown in the Win Field, located below the centre reel.
  • All payouts for Cat in Vegas slot are displayed on the Paytable, which is accessed via the Info button. A Line Win is calculated by taking the figure from the Paytable by the Line Bet.
  • Only the highest win is paid on each payline. Multiple wins (on different paylines) are added together and paid as a total win.

Info Pages:

Select the Info Button to access the various Info Pages, including the Paytable. You can move through the different pages using the arrows on the bottom right of the screen. Click the Back button to return to the reels. The Info Pages are described below:

Paytable – this page displays all payouts for winning combinations.

Wheel of Luck – this page describes the Wheel of Luck in-reels feature.

Vegas Slot Bonus – this page describes the rules and awarding of the Vegas Slot Bonus.

The King Show Free Games – this page describes the rules and awarding of Free Spins.

Paylines – this page displays illustrations showing how all 20 paylines appear on the reels.


Paylines are the directions that matching symbols must follow across the reels (left to right) to pay as Line Wins. Only the paylines 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 individual wager on each payline. The Total Bet is the total wager on all paylines (added up).

About Payouts:

All potential payouts for the main game are displayed on the Paytable. Line Win = Payout x Line Bet.

Only the highest value Line Win is paid on each payline. Multiple wins can occur on different paylines; these are added together and paid as a total win.

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

Wild Symbol:

The Wild Symbol can substitute for all other standard symbols to form the best possible Line Win on a payline.

The Wild Symbol cannot substitute for any of the Scatter Symbols (explained below).

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

Scatter Symbols:

There are three Scatter Symbols uses in Cat in Vegas slot. They do not need to appear on any paylines to be active in the game.

  • Free Games are awarded if three King Show Scatter Symbols land on Reels 2, 4 and 5 simultaneously.
  • The Vegas Slots Bonus is awarded if three Bonus Scatter Symbols land on Reels 1, 3 and 5 only.
  • The Wheel of Luck Bonus is awarded if the Wheel Scatter Symbol lands on Reel 3.

Wheel of Luck Bonus:

The Wheel of Luck Bonus work as follows:

  • The Wheel of Luck will expand and appear on the reels. You will be prompted to click Spin, which will make the Cat spin the Wheel of Luck.
  • The Wheel is made up of segments with the following Multipliers: x1, x2, x3, x4 and x5.
  • Whichever segment the Wheel pointer lands on will multiply your Total Bet. When a Multiplier has been awarded, that segment will be unlit on the Wheel. You will then be prompted to spin again. The total current win is shown in a display on the right of the Wheel.
  • From time to time, the Cat may nudge the Wheel after it stops to award a higher Multiplier.
  • You can keep spinning the wheel until the Wheel pointer lands on an unlit segment. This will end the Wheel of Luck Bonus.

Please note: the Total Bet used for the Multiplier in the Wheel of Luck Bonus will be the same as the triggering spin.

King Show Free Games:

Three King Show Scatter Symbols landing consecutively on Reels 2, 3 and 4 will award the feature. It works as follows:

  • A new screen will be launched. On the new screen, a silhouette of the Cat will begin to dance. As it dances it will add Free Games for the Bonus. When the lights go up the total number of Free Games will be displayed. You can earn between 7 and 20 Free Games.
  • When the lights go up, the Cat will add between 3 and 5 Wild Symbols to the reels. These will stay in that position for every spin in Free Games.
  • Free Games will play automatically. The remaining amount of Free Games is displayed on the top left of the screen. The total current win is shown on the top right of the screen.
  • The extra Wild Symbols will substitute for all other standard symbols during Free Games.
  • Free Games are played at the same Line Bet and number of paylines as the triggering spins.
  • The Vegas Slots Bonus and Wheel of Luck Bonus cannot be triggered during Free Games.
  • Free Games cannot be retriggered.
  • When all Free Games have been played through, a summary screen will appear displaying the total win.
  • Click Continue to return to the reels.
