What is behind the reels: RNG, symbols and the math model.
A modern online slot is not "spinning reels" but a mathematical model: a random number generator (or provably-fair algorithm) determines each spin's outcome, and the animation merely visualises the result. RTP, volatility and bonus frequency are built into this model during development and checked by auditors. Reels and symbols are decoration over probabilities. Understanding this removes myths about "hot" machines and "times when a slot pays".
