Scruffy Duck makes the Free Spins choice on the player’s behalf. Three Scatters on reels three, four or five open the feature, then a duck reveals one of five randomly selected modes, each with its own spin count and rule. Some modes multiply wins or remove low-paying symbols; others add Colossal or recurring Random Wilds. The common thread is an Expanding Wild that appears in both the base game and bonus, but its reel restrictions change during Colossal Wild play.

A fixed-line game with stacked symbols
The official record describes five reels, three rows and 25 lines. Duck symbols appear in stacks in the main game and Free Spins, and a visible part of a stack can contribute to a winning bet line under the paytable. Expanding Wilds also appear in both modes, substitute for all symbols except the Free Spins symbol and pay the highest possible line win. Outside Colossal Wild, they can land on any reel; during that feature they are restricted to reels one and five.
Three Free Spins symbols on reels three, four or five in the main game trigger the bonus. The player chooses one of five ducks, but the selected duck reveals a randomly chosen feature. The available modes therefore are not freely selectable, and the number of spins depends on which feature appears. Additional Free Spins cannot be won. That makes the trigger a choice of presentation rather than a choice of mechanic: the feature outcome remains random after the duck is picked.
Five modes, different durations
The Multiplier Feature awards 15 spins and applies ×3 to all wins. Symbol Removal awards 12 spins and removes low-paying symbols. Colossal Wild gives 10 spins with 2×2 or 3×3 Wild blocks on reels two through four; if a block forms a winning line it splits into two to nine ordinary Wilds. Random Wilds awards eight spins and places two to five Wilds after every spin. Those Wilds do not expand, cannot land on Colossal Wilds, and interact with an Expanding Wild conditionally: if the overlap creates a win, the Expanding Wild expands over it; otherwise the Random Wild overlays it.
Double Feature is the shortest at six spins and randomly combines two of the preceding modes. Each option changes more than duration, so the number of spins alone is not a measure of strength. Colossal Wild also has a special relationship with ordinary Expanding Wilds: in its mode, those expanders are limited to the outer reels, while the large blocks occupy the middle three. The official packet describes how a Colossal block splits after forming a winning line but does not state any separate multiplier for it. No such modifier is inferred.
Reference math and uncertainty
The exact-title record lists RTP 96.38%, volatility 5.8 and a maximum payout of 1,200× bet. It identifies the game as 5×3 with 25 lines. The figures do not show the probability of any particular duck, feature or Double Feature combination, and the maximum-win probability is not recorded. The feature structure is specific; its frequency remains unknown.
Strengths and weak points
Strengths
Five bonus modes alter the game in materially different ways, and their fixed spin counts make the contrast visible. Colossal blocks and Random Wilds also have explicit interaction rules.
Weaknesses
The player chooses a duck but not its feature, and no additional Free Spins can be won. The source gives no odds for each mode or for its maximum payout.
Our Editor’s View
Scruffy Duck’s variety comes from five bonus modes that change both the number of spins and the way the reels behave. The ×3 mode is a direct multiplier; Symbol Removal changes the symbol pool; Colossal Wild creates large blocks that can break into ordinary Wilds; Random Wilds adds symbols after each spin; and Double Feature pairs two rules for a shorter round. Dino Drop’s sticky Wild reels offer a persistent-Wild contrast, while Scruffy Duck’s key distinction is that a randomly revealed mode determines which reel rule applies. Meanwhile, Expanding Wilds bridge base and bonus play but shift to the outside reels in Colossal mode. This gives the feature selection a clear mechanical identity, yet the player cannot choose which rule set the duck reveals, and the bonus cannot retrigger. It suits players who enjoy varied, surprise-driven rounds and can follow changing Wild behavior; those who prefer control over bonus type or a consistent spin count may find the random selection limiting.
