Hacksaw Gaming released Wicked Grin on October 8, 2026, introducing a new online slot built around expanding symbols, coin-based payouts, and two distinct free spins bonuses. The game features a monochrome cartoon setting led by Boney Bill, a grinning skeleton character who appears alongside the reels.
The launch adds another title to the developer’s collection of dark, playful games, following releases such as Pray for Six and Six Six Six. Wicked Grin uses a 5×5 grid and a scatter-pays system, with winning combinations formed by landing at least six matching symbols anywhere on the playing area. Winning combinations also activate cascades, allowing new symbols to fall into the grid and create further opportunities for payouts.
Hacksaw Gaming has assigned the game a maximum win of 10,000 times the player’s stake. Its mathematical model has medium volatility, while the standard return-to-player (RTP) setting is 96.27%. Operators can select alternative RTP configurations of 94.32%, 92.28% or 86.28%.
A Scatter-Pays System Built Around Expanding Symbols
Wicked Grin draws on a retro cartoon aesthetic, with a dark background featuring moving monochrome circles. The central grid contains five reels and five rows, while Boney Bill stands beside the playing area. The background changes to a checkerboard pattern during the bonus rounds.
The game combines traditional card-suit symbols with higher-paying fruit and number icons. Clubs, diamonds, hearts and spades form the lower-paying group, while grapes, watermelons, golden bells, cherries and sevens occupy the higher-paying category. The payout depends on the number of matching symbols, with combinations of 17 or more paying 25 times the stake for lower-paying symbols and between 50 and 100 times the stake for higher-paying symbols.
Winning combinations disappear through the cascade mechanic, allowing symbols above them to drop and new symbols to enter the grid. The process continues while subsequent drops produce additional wins.
Its central feature revolves around Wicked Grin symbols, which expand when they land on the bottom row. Once the initial wins have been settled, an expanding symbol transforms every position on its reel into either a Coin or a Multiplier.
Coin symbols come in four varieties, with values ranging from 1x to 500x the stake. Bronze coins carry values of 1x to 4x, silver coins range from 5x to 9x, and gold coins offer 10x to 50x. Diamond coins can reach 500x, with available values of 100x, 150x, 250x and 500x.
Multiplier symbols affect coins positioned above them, as well as coins on neighboring reels in rows above the multiplier. Their values can reach 20x, and when several multipliers appear, the game applies their values to the relevant coins one at a time. Multipliers cannot land on the top row.
The expanded Super Wicked Grin symbol adds another layer to this mechanic by triggering other Wicked Grin symbols on the grid to expand from their current positions. This can bring multiple reels into the same sequence. Only one type of Wicked Grin symbol can land on an individual reel at a time.
Two Free Spins Bonuses Offer Different Coin Mechanics
Free spins begin through the game’s spreading scatter feature. When at least one FS or Super FS symbol lands on the bottom row, it expands across its reel. Each position covered by the symbol displays a value of one, two or three free spins, and the game adds these values together to determine the award.
The two scatter types cannot appear on the grid simultaneously, and no more than two scatter or Super Scatter symbols can be present at once. Landing an expanding FS symbol activates Stash N Stack, while an expanding Super FS symbol triggers Coin Craze. Both bonus rounds award between five and 30 free spins.
Stash N Stack retains the core gameplay while adding a multiplier stash above every reel. Each stash begins at 1x. When a Wicked Grin symbol expands, the stash multiplier applies to all coin values on that reel. Its multiplier then increases by 1x for the next free spin, allowing subsequent expansions to use a higher value.
The bonus can retrigger when additional expanding scatter symbols land, awarding further free spins. The total additional award can reach 30 spins, according to the game’s feature description.
Coin Craze uses a different system to track payouts during the bonus. Each reel has a Coin Collector that starts at a value of 1. Whenever a Wicked Grin symbol expands, the collector saves the coin values from that reel until the feature ends.
Multipliers also affect the accumulated amounts. When a multiplier appears during an expansion, it applies to the relevant coin values and increases the saved value in the collector on that reel and adjacent reels. At the end of the bonus, the game combines the values stored in all Coin Collectors and awards the resulting total.
Players can also access four feature-buy options, although the published descriptions contain a discrepancy over the price of Coin Craze. BonusHunt FeatureSpins costs 3x the stake and makes a bonus five times more likely to trigger on each spin. Grinny FeatureSpins costs 50x and guarantees either a Wicked Grin or Super Wicked Grin symbol on the reels. Both options use high-volatility settings, with stated RTPs of 96.39% and 96.23%, respectively.
The Stash N Stack purchase costs 80x the stake and carries an RTP of 96.26%. Hacksaw Gaming’s launch information lists Coin Craze at 250x, with an RTP of 96.28%, while another game description gives its purchase price as 200x the stake. The supplied information therefore does not establish a consistent price for that option.
Czech Republic Partnership Extends Hacksaw Gaming’s Reach
The Wicked Grin launch comes as Hacksaw Gaming continues to expand its distribution across Central Europe. The company has entered a partnership with Sazka Hry, a brand of Allwyn Česko, to make its games available to players in the Czech Republic.
Hacksaw Gaming said the agreement brings its portfolio to another locally established operator and increases its reach in the country’s licensed online gaming sector. Following the partnership, the supplier is live with operators representing more than 30% of the Czech Republic’s locally licensed online gaming market.
