City Slots — Where the High-Cap Games Live

A feature round where triggering symbols lock in place across several re-spins while the reels continue spinning, giving you chances to collect additional matching symbols before the round ends.

High volatility means individual spin results swing widely — longer stretches without a payout, followed by larger single-round returns when the feature does land. Prize-style slots typically sit in this category.

A bonus round built around collecting fixed or progressive prize values rather than a simple free-spin multiplier. Cape Cod Jackpot and Golden Gate Legends both use prize-collecting bonus structures.

Return to Player — a percentage published by the game studio showing theoretical long-run payout across millions of spins. It describes mathematical probability, not any single session's actual result.

A multiplier that grows during a feature round — either through collected symbols or consecutive wins — before applying to your total payout. Gates of Olympus uses this mechanic in its tumble feature.

A random number generator independently tested by an accredited lab to confirm that spin outcomes are statistically unpredictable. Studios like Pragmatic Play publish their RNG certification documents publicly.
