c) the pack must not be reshuffled except as provided by the rules of the game depicted; and
d) as cards are removed from the pack they must be immediately used as directed by the Rules of the game (i.e. are not to be discarded due to adaptive behaviour by the gaming machine).
Ball Drawing Games
3.9.63 The consequences for games depicting balls being drawn from a barrel (e.g. Keno) are as follows:
a) at the start of each game only balls applicable to the game are to be depicted;
b) balls once removed from the barrel must not be returned to the barrel except as provided by the rules of the game depicted;
c) the barrel must not be re-mixed except as provided by the rules of the game depicted; and
d) as balls are drawn from the barrel they must be immediately used as directed by the Rules of the game (i.e. are not to be discarded due to adaptive behaviour by the gaming machine).
Roulette Wheel, Spinning Reels, Dice Rolling, Coin Tossing Games
3.9.64 The consequences for games depicting or involving either:
a) the spinning of reels (such as “slot machines” or “poker machines”);
b) the spinning of wheels (such as roulette);
c) the rolling of dice;
d) the tossing of coins; or
e) other similar depictions
are covered by the following requirements:
i) for each reel/wheel/dice/coin, etc. depicted, the probability of any one face appearing must be as for the actual physical device (e.g. 1/20 for a 20 faced reel or wheel; 1/6 for a 6 faced dice; 1/2 for a coin);
ii) if virtual reels which map to physical reels are used, each of the reel stops of the virtual reel strip must have the same probability of occurring (i.e. if the virtual reel consists of n positions, the probability of occurrence of each position must be 1/n). Symbols of the physical reel must appear to the player in the same arrangement as would the corresponding symbols of the virtual reel (i.e. it must not be possible to determine by observing the symbols displayed on the machine that the physical reels are used instead of virtual reels). This observation extends to all symbols visible to the player. Accordingly, mapped symbols must have identical sequences of preceding and following symbols (if these symbols are visible to the player) on both the physical and virtual reel strip);
iii) the behaviour of each reel/wheel/dice/coin, etc. must be independent of (i.e. uncorrelated with) all other reels/wheels/dice/coins, etc.; and
iv) the behaviour of each reel/wheel/dice/coin, etc. must be independent of (i.e. uncorrelated with) its previous behaviour.
Other Games
3.9.65 Game fairness objectives for other games such as horse/car/animal racing, golf/football, virtual reality, etc. will be assessed on a case by case basis applying the general game fairness objectives specified earlier in this document.
3.9.66 Any games which have a finishing sequence shall display all of the sequence, eg a race will display all contestants finishing.
