f) Once the player has selected a multiplier, it must be clearly stated on the screen which
multiplier was selected.
5.1.8 Games with Metamorphic Features. Games with features that are not completely
independent of the player's history (i.e. metamorphic) shall meet the following rules:
a) Display clearly to the player which game rules apply to the current game state;
b) The game rules must be accessible at anytime from the current game screen;
c) Display to the player sufficient information to indicate the current status towards the
triggering of the next metamorphosis of the game (e.g. if the game collects tokens
towards a feature, the number of tokens missing or the total number required to trigger
the metamorphosis shall be indicated along with the number of tokens collected at that
point);
d) Not adjust the likelihood of a metamorphosis occurring, based on the history of prizes
obtained in previous games (i.e. games shall not adapt their theoretical return to player
based on past payouts);
e) Not be misleading. If a game's metamorphosis is triggered after accruing a certain
number of tokens or combination of tokens of different kinds, the probability of obtaining
like tokens shall not deteriorate as the game progresses (e.g. for identical tokens it is not
permitted that the last few tokens needed are more difficult to obtain than the previous
tokens of that kind);
f) The game's player return over the cycle of both the metamorphic and non-metamorphic
part of the game shall conform to the minimum theoretical return to player minimum
%RTP;
g) If a metamorphic feature game requires extra credits to be wagered and the game
accumulates all winnings (from the trigger and the feature) to a player win display (rather
than directly to the player's credit display), the game shall:
i) Provide a means where winnings on the player win display can be bet (via the
credit display) to allow for instances where the player has an insufficient credit
balance to complete the feature;
ii) Transfer all credits on the player win display to the player credit display upon
