If the outcomes are kosher, it follows the source code is too.
The outcomes can demonstrate that the RNG is producing random results and that the RTP is as it should be.
There are two concerns that they don't necessarily address.
1 - Juicing. i.e. Is a slot mapping the results of the RNG to a set of outcomes that increase the 'excitement' of the experience for the player?
Here's a simplified example of what I mean
Let's say you have an RNG that cleanly produces a number between one and nine inclusive.
You could map that to the following set of outcomes
9 pays 9 pounds
8 pays 8 pounds
7 pays 7 pounds
6 pays 6 pounds
5 pays 5 pounds
4 pays 4 pounds
3 pays 3 pounds
2 pays 2 pounds
1 pays 1 pound
This pays an average of 5 pounds across the nine results and is what one might expect.
But what if that number from 1-9 was mapped to this
9 pays 9 pounds
8 pays 9 pounds
7 pays 8 pounds
6 pays 5 pounds
5 pays 5 pounds
4 pays 5 pounds
3 pays 2 pounds
2 pays 1 pounds
1 pays 1 pound
This would give a much more exciting experience to the player by increasing the incidence of top line hitting
but would still average out at 5 pounds across all the nine results. And the RNG could still be clean as a whistle.
2 - Fixed RTP. This would be impossible for an outcome based test to spot, because it is delivering the expected results (guaranteed, not theoretical). So if eg the house was down and some support/resistance bounce point was triggered then the RNG could map to a set of player outcomes that would feature less top lines and more weak results, still with
(a)a totally clean RNG and
(b)all paylines being hittable (albeit in greater or lesser proportions) and
(c)an overall RTP matching player expectation
until the running RTP moved back to a point closer to the Fixed RTP level.
Both of these are simplified speculative examples, but in theory both juicing and RTP Fixing could exist alongside clean RNGs, reel strips and outcome based testing.
So what would be nice would be some cold hard facts to satisfy all of us naturally inquisitive
paying customers.
And on that note, please Mark do post the article you mentioned.
