The Mathematics of RTP (Return to Player): Theoretical Hold vs. Short-Term Variance
Return to Player (RTP) is the theoretical percentage of all wagered money that a slot machine is programmed to pay back to players over an infinite statistical horizon (typically millions of simulated spins). Calculated as $100\% - \text{House Edge}$, RTP is a long-term convergence metric governed by the Law of Large Numbers. It does not guarantee short-term returns or dictate session-level variance.
