Special Reels
Feature Reel
A special reel at the top that triggers features
A 'Feature Reel' is a horizontal reel that operates independently of the main vertical reel grid. It doesn't create payline wins on its own; instead, it spins at the top or bottom of the grid and interacts with it. The primary purpose of the Feature Reel is to act as a trigger: when a symbol on it 'matches' the symbols on the vertical reel it's paired with, it activates a powerful bonus, such as turning all matching symbols into Wilds or Coins.
Special Reels
Symbol Attraction
The power to pull symbols like a magnet
Symbol Attraction is a mechanism that forcibly moves scattered symbols on the reels to a single point, benefiting the player. This feature helps players win in various ways, such as by gathering Wilds or high-value symbols to create winning combinations, or by collecting scattered cash symbols for an instant payout.
Special Pays
Prize Board
Another winning board above the reels
Prize Board is a feature where a special board displaying various rewards (instant prizes, jackpots, free spins, etc.) exists separately from the reel grid, usually at the top or side of the reels. The core of this feature is to provide a second, completely different winning opportunity apart from regular reel wins. Players simultaneously anticipate both the results on the reels and whether a good prize will appear on the prize board, as well as whether the 'trigger' combination to win it will land on the reels.
Special Wilds
Symbol-Generated Wild
A win that creates another wild
Symbol-Generated Wild is a feature combined with cascading (tumble) reels, where a wild symbol is randomly created in one of the empty positions left behind after a winning symbol cluster explodes and disappears. The core of this feature is that the successful result of a 'win' goes beyond just dropping the next symbols; it provides a highly rewarding cycle by directly creating a powerful 'wild' that helps guarantee the next chain reaction.
Special Reels
Inverted Cascade
Winning symbols stay in place
Inverted Cascade is a highly original mechanism that completely reverses the rules of a standard 'Cascading Reels' feature. The core of this feature is that when a win occurs, the winning symbols 'stick' in place, and only the non-winning 'dud' symbols disappear, with new symbols falling into their empty spaces. This provides the player with the visual pleasure of watching their winning cluster progressively grow larger.
Special Symbols
Persistent Symbol
A powerful ability that never fades
Persistent Symbol is the most powerful and valuable top-tier special symbol found in 'Hold and Respin' bonus rounds. The core of this feature, unlike a regular special symbol (e.g., a Collector) that activates only 'once' upon appearing, is that it repeatedly performs its special ability on every single respin until the bonus round ends. This 'persistence' is what pushes the game's potential to its absolute limit.
Special Pays
Bonus-Only Payout
Only the bonus matters
Bonus-Only Payout is a highly experimental and unique payout system that completely flips the traditional rules of slots. This method does not pay out any winnings for any symbol combination in the base game (regular spins). The core of this feature is to condense all of the player's goals and expectations into one single moment: 'entering the bonus game'. The base game only serves as a 'raffle for an entry ticket' to the bonus; the only path to winning prizes is the bonus game itself.
Special Spins
Reel Shift Respin
Sideways reels bring new chances
Reel Shift Respin is a unique respin feature where, after a win occurs, the entire reel grid shifts horizontally by one position, and the empty reel on the edge is filled with new symbols. The core of this feature is to act like a 'conveyor belt' where the game board itself is constantly moving and opening up new combination possibilities, creating a chain reaction where a single win can lead to an endless succession of wins.
