An update that does not impact game fairness is referred to as a minor update and can be released without the need for external retesting. The Commission have adopted a high-level principles based approach to defining major and minor updates. These principles, set out in the below table, are supported by non-exhaustive examples of major and minor updates.
High level principle:
A major update, which will require external retesting by an approved test house, is any software change which may affect the fairness of a game. Fairness elements would include any change to the RNG, scaling and mapping, or game rules* (including how the rules are processed by the software).
All updates which do not fall within the definition of major update, can be dealt with as minor updates.
Issue: Inefficient logging issues causing performance impact on the game and CPU due to load.
Fix: Amended how the game symbol arrays were constructed, allowing for faster game and reduced CPU load.
Although no rules were changed the software implementation of the rules has changed requiring independent testing.
Issue: Bonus round win calculation update for rarely encountered scenario.
Fix: Correct calculation in line with game design and stated rules.
This example represents an update required due to the incorrect rules implementation coding of the original release.
Licensees, in conjunction with their test houses, will be expected to use their own judgement as to those changes that do not affect game fairness.
*Game rules in this context refers to the underlying maths and design of the game – pay tables, symbol distribution, feature rules etc. Collectively the game rules determine the overall game RTP. Some might also call this the game logic. It is not meant to mean that a tweak to the game rules and artwork as presented to the player (for clarification purposes) constitutes a major change.
