1.22.13 Games that have a component of strategic skill (e.g. Draw Poker and Blackjack) must meet the following requirements:

a) the player return for the optimal strategy must not exceed [MAXRTP] and must not be lower than [MINRTP];

b) where an automatic hold feature or strategy advice is provided to the player, the player return must not be lower than [MINRTP] when calculated using the selections provided by such a feature or using the advice provided;

c) where an automatic hold feature or strategy advice is provided to the player, it must be fair and not misleading; and

d) the player must be able to override any automatic hold feature and reject any or all strategy advice provided.

Prize Determination

1.22.14 Prize determination shall:

a) be clearly specified on the exterior of the device, or easily accessible to the player; and

b) be exclusively a consequence of the outcome of a computer based RNG in conjunction with the prevailing payout table and rules of the game.

c) be attainable combinations of the mapped symbol set (except random prizes).

Game Minimum RTP

1.22.15 A game must have a theoretical/estimated statistical expectation that the minimum player return (RTP) of the game will be greater than or equal to [MINRTP].

Game Maximum RTP

1.22.16 A game must have a theoretical/estimated statistical expectation that the maximum player return (RTP) of the game will be less than or equal to [MAXRTP].

Probability

1.22.16a The probability for attaining each winning pattern of symbols (offered in the Base game) must not be less than 1/7,000,000 (at a rate of at least 1 in 7 million plays).

The calculation of the probabilities is to:

a) be multiplied by the maximum number of possible lines, ways or patterns available in one play (using the configuration which provides the lowest number of 'maximum lines' etc. available in one play);

b) combine the probabilities for the same winning pattern when occurring in different elements of a play (e.g. base and feature elements);

c) combine the probabilities for the same winning pattern occurring with and without substitute symbols;

d) exclude ‘multipliers’; and

e) ignore all linked progressive jackpots.

Standard Deviation

1.22.17 The Nominal Standard Deviation (NSD) of a game must be no greater than 15.

While the standard deviation of individual components of a game (e.g. feature games, metamorphic sequences etc.) may exceed 15, the NSD of the whole game must not exceed 15.

In determining the NSD for a game, the following conventions must be applied:

a) Calculate standard deviation of the base game at minimum bet and single line play or equivalent. (Should the underlying game algorithm or randomising mechanism change with a change to play options selected (e.g. different virtual reels are activated upon a change to the number of lines played or certain prize categories are only available by selecting specific play options), the highest standard deviation result must be used);

b) Coinciding prizes are to be treated as separate prizes (e.g. a payline prize of 20 coinciding with a scatter prize of 50 are to be treated as two separate prizes of 20 and 50);
