How Do Slot Games Work?
In slot games, a Random Number Generator (RNG) determines the outcome of every spin. This means each spin is completely independent and has no connection to the previous one.
Most modern slots include:
- Wild Symbols — substitute for other symbols to complete a win.
- Scatters and Free Spins — landing certain symbols triggers a round of free spins.
- Multipliers — multiply your winnings by several times.
- Bonus Rounds — a special trigger takes you into a separate gameplay mode.
- RTP (Return to Player) — the statistical rate at which a slot returns a portion of total wagers as prizes over the long term. A higher RTP means better returns over time.
