Auxiliary Prize/Multiplier Reel
Auxiliary Prize/Multiplier Reel is a unique vertical reel that spins independently alongside the main game grid, applying either win multipliers or fixed jackpot values to any wins on the main reels.
Reel Expansion
Reels are meant to be changed
Reel Expansion is a feature where the physical size of the game grid (reels or rows) actually gets bigger, typically upon entering a bonus round like free spins.
This goes beyond simply adding a multiplier; it aims to expand the 'board' of the game itself, providing players with a wider field of opportunity and fundamentally increasing the number of winning ways.

VIEW ALL
Auxiliary Triggered Reel
An additional reel positioned above the main game grid that spins independently and awards multipliers or a collector symbol when a full stack of identical symbols appears on a corresponding main reel.

The Eclipse Feature Trigger is a bonus activation system that requires specific 'Moon' and 'Sun' symbols to align horizontally on the same row, with the intermediate symbol determining the type of bonus awarded.
Expanding Collector Reel
This feature transforms a single 'Collect' symbol into a full-reel collector upon landing, which then sweeps all visible cash prize symbols from other reels.

Full Paying Symbol Cascade
If all paying symbols are destroyed in a single cascade, the following cascade will consist entirely of a single kind of paying symbol.
Gem Block Destruction & Fill
Special Gem Blocks (e.g., Red, Blue, Green) destroy all symbols of their matching color-class on the reels, and then ensure only symbols of that same kind drop in the subsequent cascade.
Grid Reset
A feature that removes all symbols from the grid and replaces them with a completely new set of symbols.
Horizontal Multiplier Reel
Horizontal Multiplier Reel is an innovative reel mechanic where a dedicated horizontal reel, positioned above the main game grid, spins to reveal multiplier values that directly enhance all winning combinations achieved on the main reels in that spin.
Inverted Cascade

Sequential Wild Reels
A feature where a new reel turns into a 'Wild Reel' in a set sequence with each spin.
Splitting Colossal Symbol
A feature where a single giant symbol 'splits' into smaller-sized symbols over multiple stages.
Stackways Engine
The Stackways™ engine is a unique reel mechanic where each reel can randomly display a variable number of symbols, typically ranging from 2 to 10 in the base game, which dynamically changes the number of ways to win, and can expand further in bonus rounds.
Stepper Feature
A unique mechanic where uncollected bonus or jackpot symbols nudge down one position on the subsequent spin, offering an additional chance to trigger a bonus.
Super Cascade Reels
An enhanced version of cascading reels where a win removes all symbols of the 'same kind' from the entire screen.
Symbol Attraction
A feature where a special 'magnet' or 'collect' symbol appears and pulls other specific symbols on the reels toward itself.
Symbol Removal
A feature that temporarily removes specific symbols (usually low-value ones) from the reels, allowing winning combinations to be formed only with higher-value symbols.
Symbol-to-Mini-Slot Transformation
This feature transforms a regular symbol on the main reels into a fully functional single-reel mini-slot machine, which then spins to award unique prizes like multipliers, free spins, or bonus game triggers.
Synchronized Reels
A mechanic where two or more separate reels are linked to land with the exact same symbols.
Fixed Non-Rectangular Grid
This feature establishes a fixed, non-rectangular active playing grid where only specific symbol positions within a larger visual layout are active for symbol landing and win evaluation, creating a unique and static reel shape.
Position Activation and Merge
Winning symbols activate their positions on the reels; positions become partially activated on the first win and fully activated on the second, with adjacent fully activated positions then merging into larger blocks from 2x2 up to the full 5x6 grid.
Grid Rotation
A feature that physically rotates the entire game grid by 90 degrees, repositioning all symbols and potentially creating new winning opportunities based on the new orientation.
Reel-Specific Symbol Selector
Each reel has an independent symbol selector above it; if the selected symbol lands on the reel, all symbols on that reel transform to match the selected symbol.
Electric Reels
Electric Reels introduce a dynamic reel state that causes landing wilds to expand fully and double their multiplier, significantly boosting win potential.
Independent Position Reels
This feature redefines the game grid, transforming each individual position into its own independent spinning reel, creating unique winning dynamics.

Designated Feature Reels are specific reels within the main game grid that are pre-assigned to host unique dormant features, which activate under specific trigger conditions involving other symbols and can be progressively upgraded.
Vertical Reel Shift Respin
During a free spins mode, the entire reel grid dynamically shifts down one row after each win, revealing a new row of symbols at the top and triggering a respin.
