What is Bonus Round?
A special feature within a slot game, typically triggered by landing scatter symbols or specific combinations, that offers enhanced prizes such as free spins, multipliers, or a pick-and-win game. Most of a slot's variance (big win potential) is concentrated in the bonus round.

Multiplier

Variance (Volatility)
Describes how a slot distributes its payouts — the balance between win frequency and win size. Low variance means frequent small wins; high variance means rare but potentially large wins. Also called volatility.
