I get the feeling we’re talking at cross purposes a bit here!
Argyl’s statement around the dice is mathematically correct, but the application is different to what ayma is talking about (I believe).
If you deposit £20 on three separate sessions, this is exactly the same as depositing £60 on one single session, assuming all other variables (stakes, RTP etc.) remain the same. There is no advantage, nor disadvantage.
Apologies if I’ve misunderstood anyone here.
