Kraken Gold Rush

Winning symbols are removed and new symbols drop into the gaps, so a single spin can pay several times before it ends.

What it means for you: Raises the ceiling of any one spin and lengthens it. Sessions feel streakier than the hit frequency alone suggests.

Symbols in a winning combination explode; symbols above cascade down to fill the gaps, forming a new round. This repeats until no more winning combinations form, then payout is made.

A triggered round of spins that costs nothing and usually changes the maths.

What it means for you: Where most of the return lives in modern slots. How long it takes to reach is the feature frequency.

3 Scatter symbols appearing anywhere trigger the Free Spins Feature with 10 free spins; each additional Scatter awards 2 more. Free spins can be retriggered. The feature carries its own escalating multiplier wheel (see the progressive-multiplier link).

The free-spins round can be bought outright for a fixed multiple of the base bet, skipping the wait.

What it means for you: Compresses a long session into one purchase, and usually at a different RTP from the base game.

A Feature Buy menu lets a player buy directly into the Free Spins Feature at a price the sheet says is displayed in the Feature Buy menu itself. No purchase price or purchased-play RTP figure is published on any page read this run.

The multiplier climbs each time a condition repeats, such as every tumble or every retrigger, and usually resets when the feature ends.

What it means for you: The dominant source of extreme outcomes in modern grid slots; it is why a tumble chain's length matters more than any single clearance in it.

The Free Spins Feature's multiplier wheel starts at x5 and, every 3 winning rounds within the feature, climbs one level up the wheel: x5, x10, x15, x20, x25, x30, x35, x40, x45, x50, x60, x70, x80, x90, x100. At the end of each free spin, the wheel's current level applies to whatever that spin already won.

Wins come from groups of touching identical symbols anywhere on the grid, usually five or more, rather than from lines or reels. It is almost always paired with tumbling reels, because clearing a winning cluster is what lets the next one form.

What it means for you: Long chains of small clearances broken up by rare grid-filling events. The volatility lives in the length of the chain rather than in any single spin.

Any combination of 4 or more matching symbols touching horizontally or vertically anywhere on the 6-column, 5-row grid forms a winning combination.

A wild symbol stays in place for a set number of spins or for the remainder of a feature, taking part in every winning combination it touches while it holds its position.

What it means for you: Makes free-spin and bonus rounds compound over their duration, shifting return from the base game into the feature and raising volatility.

The Wild Kraken symbol occupies the third row of reels 3 and 4 on every spin and remains on the reels for the whole of that spin's cascade sequence. It substitutes for all symbols except Scatter. The provider's own sheet does not describe it as landing and locking; it is present by design on every spin rather than triggered, the closest fit in this project's curated mechanic set.

A fixed multiplier factor applies to wins, usually inside a feature, stated as a single value or a capped range rather than a progression.

What it means for you: Scales the whole feature's payouts. The biggest wins on the game are usually a multiplier event rather than a paytable one.

During any main-game spin with 3 or more winning (cascade) rounds, once no more winning combinations remain, the total win of that spin is multiplied by a fixed x5 before wins are paid.
