Hacksaw’s Boney Bill Hides 10,000x Behind a Wicked Grin

A slot that drains every colour out of its own artwork takes a certain confidence, and Wicked Grin has it. Hacksaw Gaming launched the game on October 8, 2026, putting a grinning skeleton named Boney Bill in charge of a monochrome comic world where coins pile up behind that smile. A smile is all it takes, or so the tagline claims, though Bill keeps a few tricks tucked away. Underneath the styling sits a coin collect engine with one of the friendliest bonus triggers Hacksaw has built.

Game Overview

Wicked Grin runs on a five by five grid with an All-Scatter win type, so paylines never enter the conversation. Symbols pay from anywhere they land. The whole game revolves around converting full reels into stacks of coins, which makes reel position matter far more than symbol matching. Here is the spec sheet:

• Grid: 5 reels, 5 rows
• Win type: All-Scatter, no paylines
• RTP: 96.27% default, with operator variants at 94.32%, 92.28% and 86.28%
• Volatility: 3 out of 5 on the developer’s scale
• Max win: 10,000x the bet
• Bet range: 0.10 to 100
• Release date: October 8, 2026

Theme and Design

The art direction commits hard. Every symbol, background and animation lives in black, white and shades of grey, drawn with the thick inked outlines of an old newspaper comic strip. Boney Bill holds court beside the reels, all teeth and bad intentions.

The audio plays against the visuals, running a bouncy tune under a world that looks thoroughly haunted. That contrast hands Wicked Grin its personality, and it keeps the quieter stretches of the base game from feeling grim. Diamond Coins glinting against the grey do the rest.

Gameplay and Mechanics

Spins work differently here. Nothing needs to line up, so a result depends entirely on what the Wicked Grin symbols decide to do when they reach the bottom row. Everything else on the grid just waits its turn.

When one of those symbols touches the bottom row, it expands upward and transforms every position on its reel into Coins or Multipliers. Coins carry their own value, and Diamond Coins can reveal up to 500x. Multipliers then apply their value to all Coins above them, and the reach extends sideways too, catching Coins on adjacent reels in the rows above.

That sideways reach is the detail worth remembering, because a single well placed multiplier can inflate three reels at once instead of just the one it landed on. Values climb as high as x20. Drop one near the bottom of a loaded grid and the arithmetic turns interesting fast.

Features and Bonus Rounds

Expanding Wicked Grin Symbols

The base mechanic doubles as the headline feature. Each expanded symbol claims a full reel and rewrites it, so one landing can change the entire shape of a spin. Multiple expansions across neighbouring reels stack coins and multipliers into combinations that pay well beyond what the grid size suggests.

Super Wicked Grin Symbols

The upgraded version adds a chain reaction. A Super Wicked Grin symbol that expands forces any ordinary Grin symbols on adjacent reels to expand too, and they do it from wherever they sit. No bottom row required. One landing can ripple across the grid and convert reel after reel in a single sweep.

Spreading FS Symbols

Free spins in Wicked Grin arrive through FS and Super FS symbols, and only one of them needs to reach the bottom row. Every FS symbol on screen then expands to cover its entire reel. The spin count comes from adding up the values printed on the positions those expanded symbols cover, so the length of the round depends on where they land.

Stash N Stack

One expanding FS symbol is enough to open Stash N Stack, a round of 5 to 30 free spins. A Stash sits above each reel and multiplies the Coin values landing beneath it, so no two reels carry the same weight once the round starts. Catching a fat Diamond Coin under a heavy Stash does the damage here.

Coin Craze

Super FS symbols unlock Coin Craze instead, again running 5 to 30 free spins. Every reel gets a Coin Collector that holds onto Coin values and saves them until the bonus ends, so nothing slips away between spins. The round builds as one long accumulation.

Bonus Buy

Players who would rather skip the hunt can buy their way into the bonus games. Pricing varies between operators, so the exact cost shows up in the paytable at whichever casino hosts the game. Local rules matter too, since several markets block buy features outright.

RTP, Volatility and Win Potential

Wicked Grin ships with a default RTP of 96.27%, comfortably above the current industry average. Operators can also run it at 94.32%, 92.28% or 86.28%, and that bottom figure marks a steep drop worth checking before you spin. The in-game paytable confirms which version a casino has live.

Volatility sits at 3 out of 5 on the developer’s scale, so this plays as a medium game rather than a punishing one. That rating next to a 10,000x ceiling makes an odd pairing. Most slots reaching five figures ask for far more patience, and the single scatter trigger should keep bonus rounds coming more often than the genre norm.

Who This Slot Is For

Coin collect fans will feel at home immediately, and Wicked Grin serves them a version with far less waiting between rounds. Medium volatility suits players who want features to show up. Anyone chasing 50,000x ceilings and violent swings should look elsewhere, because Wicked Grin caps out at 10,000x and plays a steadier game.

The monochrome styling also pulls in a crowd that normally scrolls straight past coin slots. There is real identity here beyond the maths, which counts for something in a category where most releases look interchangeable. Bets run from 0.10 to 100.

Final Thoughts

Hacksaw took a familiar format and fixed the part players complain about most. Wicked Grin lets a single scatter open the door, builds the spin count from where symbols land, and rewards smart multiplier placement over raw luck on trigger counts. The black and white presentation gives it a hook the maths alone would never provide.

Boney Bill delivers on his promise, more or less. A smile really is all it takes to start a bonus round in Wicked Grin, though the Stash and the Collectors still decide how kindly it ends. For a medium volatility coin game with a 10,000x top end, that trade feels fair.
