Well spotted.
It seems we can pretty much count on a screw up of some nature from a Rival new release.
This is not a criticism of you because we all have our own opinions but personally I have no idea why anyone would play Rival slots when even Rival seem to have no idea on how the games play and the RTP is so obviously nothing to do with the paytable or probability of outcome not to mention Rivals history of shady goings on, it is beyond me I'm afraid.
That said we have had recent examples of new
RTG and MG slots screwing up in very obvious ways so the play-testing and read-proofing for new slots and their paytables is obviously sub standard to a new level of ineptitude.
Rival though are by far the worse offenders and the fact they never improve just proves to me what an amateurish operation they are.
