Slot Blast on bk win — Fast Reels, Real Features

A tumble removes winning symbols from the reels and drops new ones into their place, allowing multiple wins from a single spin without an extra bet. Common in Gates of Olympus.

Hold-and-spin locks certain symbols — usually high-value or bonus tiles — in place while the remaining reels spin again, giving extra chances to complete a feature or prize round.

A multiplier trail increases a win multiplier each time a qualifying symbol lands or a tumble occurs. The multiplier resets at the start of a new spin unless a bonus round is active.

Volatility describes how often and how large wins tend to occur. High-volatility titles like Mahjong Ways pay less frequently but can produce larger feature payouts when they do hit.

A feature buy lets you pay a set multiple of your stake to enter the bonus round directly, skipping the base game. Availability depends on the provider and your eligible region.

RTP means Return to Player — the theoretical percentage of total bets a slot returns over many rounds. It's a long-run statistical figure, not a round-by-round payout promise.
