A long-run model, not a personal result
Return to player is an expectation under a game’s rules and configuration. A short session can differ greatly from that expectation. Knowing an average alone does not identify the distribution of outcomes.
Volatility labels are incomplete
Low, medium and high are coarse descriptors, not full mathematical specifications. A credible simulation of a real slot needs more than a label and an RTP percentage.
What Variance Lab does
Casimo uses a deliberately simple, stated toy distribution to illustrate uncertainty and independent trials. It is not a reconstruction of any operator’s slot or a prediction of a redemption.
