How To Play

Wild Symbol

The WILD can appear on any reel. The WILD substitutes for all symbols except the BONUS and IN JAIL symbol.

Bonus Symbol

The BONUS symbol can appear on any reel.

  • 3 Bonus symbols activate the Big Event Bonus.
  • 4 Bonus symbols activate the Big Event Bonus with House Sneak Preview.
  • 5 Bonus symbols activate the Big Event Bonus with Hotel Sneak Preview.

Big Event Bonus

Before the feature begins the player is asked to pick from 15 Community Chest cards and 9 Chance cards. The Community Chest cards increase the number of Free Spins awarded and the number of guaranteed wins. The Chance cards control the type of free games which are awarded. These are:

  • Standard Free Games (Dice)
  • Dancing Wilds (House)
  • Sticky Wilds (Hotel)

The player continues picking, alternating between Community Chest and Chance until one of three symbols award Free Games.



  • If the Bonus is triggered with 4 or 5 BONUS symbols, 3 Chance positions will be revealed.
  • 4 BONUS symbols will reveal the location of the three house symbols.
  • 5 BONUS symbols will reveal the location of the three hotel symbols.
  • The player is still able to pick different cards in an attempt to increase the number of spins.


Guaranteed Wins:

  • Guaranteed Wins indicate the minimum number of wins available during the bonus round.
  • The Guaranteed Win meter is reduced by one for every winning spin on the reels.
  • At the end of the bonus round if any Guaranteed Wins remain then these are played out on a separate reel.


Locked Wilds:

  • During Locked Wilds’ Free Spins, all Wilds which land in the reels remain in play for the duration of the bonus round.
  • The WILD should change colour to show that it has locked.


Dancing Wild:

  • During the Dancing Wilds bonus, a 3-high Wild is present on every spin.
  • On each spin the WILD can move to another position on the reels.


In Jail Symbol

During Free Games, the IN JAIL symbol becomes active. When the IN JAIL symbol lands on the reels it eliminates the current lowest paying symbol from all future spins.
