Wicked Grin
Wicked Grin Introduction
Wicked Grin is a darkly comic slot from Hacksaw Gaming, combining the visual style of early black-and-white cartoons with an unsettling character called Boney Bill. Released on 8 October 2026, the game takes players into a strange monochrome world where smiling faces, expanding symbols and valuable coins provide the foundations for its main features.
Behind the deliberately old-fashioned presentation is a modern slot built around Scatter Pays, cascading wins and expanding Wicked Grin symbols. These special symbols can transform entire reels into Coins and Multipliers, while two different Free Spins features introduce additional ways of increasing the value of the prizes collected.
Wicked Grin is developed and distributed by Hacksaw Gaming. It has medium volatility, a highest standard RTP of 96.27% and a maximum win of 10,000x the stake.
Overview of Wicked Grin
Wicked Grin uses a 5×5 grid with a Scatter Pays system rather than conventional paylines. Winning combinations are formed by landing six or more matching symbols anywhere on the reels, meaning symbols do not need to appear on consecutive reels or follow a particular pattern.
The paytable combines traditional fruit-machine symbols with card suits and other familiar slot imagery. Cherries, grapes, watermelons, bells and lucky sevens appear alongside lower-paying symbols, giving the game a classic mechanical-slot appearance despite its more elaborate mathematical features.
Whenever a winning combination lands, the Cascading Wins mechanic removes the winning symbols and allows new ones to fall into the empty positions. If another qualifying combination appears, the process repeats, creating the possibility of several consecutive wins from a single paid spin.
The game’s most important symbols are the Wicked Grin and Super Wicked Grin symbols. When either lands on the bottom row, it expands to cover the entire reel, transforming the positions into Coins or Multipliers.
Coin symbols can reveal cash values, while Multiplier symbols increase the value of qualifying Coins. The placement of these multipliers is particularly important because they can influence Coins both above them and on adjacent reels.
The Super Wicked Grin adds another dimension by causing Wicked Grin symbols on neighbouring reels to expand from their existing positions. This can create several interacting expansions and substantially increase the number of valuable symbols on the screen.
Wicked Grin also features two separate bonus rounds, Stash N Stack and Coin Craze, both activated through expanding Free Spins symbols.
Wicked Grin RTP, Payout & Volatility
Wicked Grin has a highest standard Return to Player (RTP) of 96.27%. However, Hacksaw Gaming supplies four different mathematical configurations, allowing operators to select from the following RTP settings: 96.27%, 94.32%, 92.28% and 86.28%.
The differences are considerable. A casino operating the lowest configuration offers a theoretical return almost ten percentage points below the highest version. Players should therefore check the RTP displayed in the game’s information panel rather than assuming every casino offers the same mathematical model.
Hacksaw Gaming rates Wicked Grin at 3 out of 5 for volatility, placing it in the medium category. This is a relatively moderate classification compared with many of the developer’s more extreme releases, although substantial payouts still depend on favourable combinations of expanding symbols, Coins and Multipliers.
The betting range runs from approximately 0.10 to 100 per spin, depending on the casino and currency.
The maximum win is 10,000x the stake. This payout ceiling applies across the game’s different modes, including the base game and both bonus features.
At a stake of 1 per spin, the maximum theoretical payout would therefore be 10,000 in the same currency. As with any maximum-win figure, this represents the mathematical ceiling rather than a typical or expected outcome.
Graphics & Gaming Experience in Wicked Grin
Wicked Grin takes inspiration from the earliest era of animated cartoons, particularly the black-and-white productions of the 1920s and 1930s. Hacksaw Gaming recreates the exaggerated expressions, rubber-hose animation and slightly unsettling character designs associated with that period.
The central character, Boney Bill, is a grinning figure whose appearance combines cartoon humour with a distinctly sinister atmosphere. His enormous smile and exaggerated movements establish the game’s personality, while the monochrome setting gives the presentation a deliberately aged appearance.
The reels feature traditional fruit-machine symbols that contrast with the more unusual character design. Bells, cherries, watermelons and lucky sevens reinforce the classic slot-machine aesthetic, while the special Wicked Grin symbols introduce the game’s darker personality.
The black-and-white presentation also serves a practical purpose. Special symbols and valuable Coins are easy to distinguish from the regular paytable, while reel expansions create clear visual changes when a feature activates.
When a Wicked Grin symbol expands, the transformation of an entire reel into Coins and Multipliers provides an immediate indication that the spin has entered a more valuable phase. Multiple expansions can create a particularly busy screen as additional cash values and multipliers appear.
The soundtrack complements the presentation with old-fashioned cartoon effects and playful musical elements, helping maintain the contrast between the game’s humorous exterior and its potentially rewarding mechanics.
Rather than relying on elaborate three-dimensional graphics, Wicked Grin uses a distinctive artistic direction to give the game its identity.

Bonus Features in Wicked Grin
Wicked Grin includes two main bonus features, Stash N Stack and Coin Craze. Both are triggered through special Free Spins symbols that expand when they land on the bottom row.
The number of Free Spins awarded depends on the values displayed by the expanding symbols, with the initial allocation ranging from 5 to 30 Free Spins.
The first bonus, Stash N Stack, is activated by an expanding regular FS symbol.
During this feature, a Stash appears above each reel. These Stashes provide multipliers that increase the value of Coins appearing on their respective reels.
The Stash multipliers can grow as additional Wicked Grin expansions occur, increasing the potential value of subsequent Coins. This gives the bonus a progressive structure, with the possibility of stronger payouts as the feature develops.
A reel that initially produces relatively modest cash values can become considerably more rewarding once its Stash multiplier has increased. The strongest outcomes therefore depend on generating valuable Coins on reels where the associated multipliers have already grown.
The second bonus, Coin Craze, is activated by an expanding Super FS symbol.
Coin Craze replaces the Stash system with Coin Collectors, which accumulate Coin values throughout the bonus. Rather than relying entirely on immediate payouts, the feature allows collected values to build towards a final award.
This changes the way the bonus develops. Early Coins contribute to an accumulating total, while later expansions can add further prizes and multipliers.
The Coin Collectors make the feature particularly interesting when several reels become involved, as the combined value can increase substantially over the course of the Free Spins.
Both bonus rounds can award additional spins when qualifying FS or Super FS symbols expand during the feature. These retriggers can provide between 5 and 15 extra Free Spins per qualifying symbol, with a maximum of 30 additional spins.
The two bonuses therefore offer different approaches to the same underlying mechanics. Stash N Stack concentrates on increasing the value of Coins through reel-specific multipliers, while Coin Craze focuses on accumulating prizes for a larger final collection.
Features in Wicked Grin
The defining mechanic in Wicked Grin is the expanding symbol system. Whenever a Wicked Grin symbol lands on the bottom row, it expands to occupy the entire reel. The affected positions then transform into Coins or Multipliers, creating opportunities for instant cash prizes.
The Coin symbols can reveal values of up to 500x the stake, making them considerably more important than the regular paying symbols when the strongest combinations occur.
Multiplier symbols can carry values of up to 20x. Their influence extends beyond a single position, applying to Coins above them and to qualifying Coins on adjacent reels in higher rows.
This arrangement means that the location of a Multiplier can be just as important as its value. A multiplier positioned beneath several valuable Coins can increase the total payout considerably, particularly when multiple expanded reels interact.
The Super Wicked Grin adds another layer by triggering expansions on neighbouring reels. Instead of requiring every Wicked Grin symbol to land on the bottom row independently, the Super version can activate adjacent symbols from their existing positions.
This creates opportunities for chain reactions in which several reels transform into Coins and Multipliers during the same spin.
Wicked Grin also includes optional enhanced play modes and Bonus Buy features where permitted.
BonusHunt FeatureSpins costs 3x the normal stake and increases the chance of triggering a bonus by five times.
Grinny FeatureSpins costs 50x the stake and guarantees at least one Wicked Grin or Super Wicked Grin symbol on every spin. Free Spins symbols cannot appear in this mode, so it concentrates entirely on the expanding Coin and Multiplier mechanics.
The Stash N Stack Bonus can be purchased directly for 80x the stake, while the more expensive Coin Craze Bonus costs 200x the stake.
These options allow players to access the game’s main features without waiting for a natural trigger, although their availability depends on the casino and jurisdiction.
Each enhanced mode can have its own mathematical return, so the RTP may differ from the standard game.

Summary
Wicked Grin is an entertaining addition to Hacksaw Gaming’s catalogue, combining an unusual visual identity with a feature system built around expanding reels, valuable Coins and strategically positioned Multipliers.
The black-and-white cartoon presentation immediately distinguishes the game from more conventional fruit slots, while Boney Bill provides a memorable central character. Beneath that playful exterior, however, the mathematics revolve around the interaction between Wicked Grin symbols and the cash prizes they reveal.
The expanding reel mechanic is particularly important. A single Wicked Grin symbol can transform an entire reel into Coins and Multipliers, while the Super Wicked Grin can activate neighbouring symbols and create several interacting expansions. With Coin values reaching 500x and multipliers of up to 20x, favourable combinations can produce substantial payouts.
The two bonus features provide different ways of developing that potential. Stash N Stack rewards the accumulation of reel-specific multipliers, while Coin Craze concentrates on collecting cash values throughout the feature before awarding the accumulated total.
The game’s medium volatility makes it somewhat less extreme than many other Hacksaw releases, although its biggest payouts still require favourable combinations of special symbols. The availability of several RTP configurations is also important, particularly given the substantial difference between the highest and lowest settings.
With a 96.27% highest standard RTP, two distinct bonus rounds and a 10,000x maximum win, Wicked Grin successfully combines classic cartoon styling with modern slot mechanics. Its strongest attraction is the expanding symbol system, which gives ordinary spins the potential to develop into considerably more valuable sequences when Coins and Multipliers begin interacting across several reels.
