Wicked Grin: Boney Bill's Coin Reels

Wicked Grin is a Hacksaw Gaming slot released on 8 October 2026, built around reels that turn into Coins and Multipliers when a grinning symbol lands on the bottom row. The art is black and white, the host is a skeletal figure called Boney Bill, and the studio's tagline is simply "A smile is all it takes".

On its official game page, Hacksaw Gaming rates the volatility at 3 out of 5, lists a max win of 10,000x and describes the win type as All-Scatter. Four RTP settings are published: 96.27%, 94.32%, 92.28% and 86.28%.

A 3/5 rating places Wicked Grin in the middle of Hacksaw's own five-point scale, paired with a 10,000x ceiling.

Almost every feature in Wicked Grin is triggered on the bottom row. Wicked Grin symbols, Super Wicked Grin symbols, FS symbols and Super FS symbols only act when they land there.

That gives each spin a clear focal point. A special symbol higher up the reel does nothing on its own, so the bottom row is where to look first when the reels stop.

When a Wicked Grin symbol lands on the bottom row it expands up the reel and transforms every symbol on that reel into either a Coin or a Multiplier. Coins carry cash values; Diamond Coins can reveal values of up to 500x.

Multipliers revealed this way carry values of up to x20, applied to Coins. Each Multiplier boosts all Coins above it on its own reel, plus Coins on the adjacent reels in the rows above it.

Position therefore matters. A Multiplier low on its reel covers more Coins than one near the top, because more rows sit above it, both on its own reel and on the neighbouring ones.

The Super Wicked Grin adds a chain. When it expands, any regular Wicked Grin symbols on adjacent reels expand too, from wherever they currently sit, so one landing can convert several reels at once.

The bonus games are triggered by FS and Super FS symbols, again on the bottom row. When at least one is there, each FS symbol expands to cover its entire reel.

The number of free spins is not fixed. It is worked out by adding together the numbers on the positions covered by each FS symbol, and the resulting bonus awards between 5 and 30 free spins.

Which bonus you get depends on the symbol. Expanding at least one regular FS leads to Stash N Stack; expanding at least one Super FS leads to Coin Craze.

Stash N Stack awards 5 to 30 free spins with a Stash above each reel. Each Stash multiplies the Coin values that land on its reel.

The appeal is that the boost belongs to the reel rather than to a single spin, so Coins landing on a reel with a strong Stash are worth more throughout the feature. Watch which reels carry the largest Stash values as the round goes on.

Coin Craze also awards 5 to 30 free spins, but swaps the Stashes for Coin Collectors. These save every Coin value collected and hold it until the end of the bonus.

The difference from Stash N Stack is timing. Stash N Stack lifts Coin values reel by reel as they land, while Coin Craze builds a running total that pays out when the feature ends. Hacksaw does not publish trigger odds for either bonus on its page.

Wicked Grin ships with four RTP versions: 96.27%, 94.32%, 92.28% and 86.28%. Casinos choose which one to run, and the game looks the same in each.

The bottom setting is a long way below the top. In theory, over a very large number of spins, the 96.27% version returns about £96.27 of every £100 staked and the 86.28% version about £86.28, so the house keeps more than three and a half times as much at the lowest setting.

Open the game's information screen at any casino to see which figure applies before you stake real money.

Hacksaw Gaming offers a free demo of Wicked Grin, which is the best way to learn how the reel transformations read on screen. Focus on three things: where Multipliers appear on converted reels, how often Diamond Coins show up, and how the FS numbers add up into a spin count.

Also compare the two bonuses if you reach them, since Stash N Stack and Coin Craze pay in quite different ways. Demo results use virtual credit and say nothing about real-money outcomes. Slots are for adults aged 18 and over; decide your limits before you start.

What is the RTP of Wicked Grin?

Hacksaw Gaming publishes four RTP settings for Wicked Grin: 96.27%, 94.32%, 92.28% and 86.28%. The casino picks which version it runs, and the game looks identical in each, so open the information screen to check the figure in use. The gap of almost ten percentage points between the top and bottom settings makes that check worthwhile.

What is the max win on Wicked Grin?

The max win on Wicked Grin is 10,000x the bet, according to Hacksaw Gaming. The biggest values come from Diamond Coins worth up to 500x combined with Multipliers of up to x20, and from the two bonus games. Treat the cap as a ceiling rather than an expectation, as most rounds pay far less.

Is Wicked Grin high volatility?

No. Hacksaw Gaming rates Wicked Grin at 3 out of 5 for volatility, the middle of its scale. That is a mid-range rating, while the 10,000x max win still leaves room for large results in the Stash N Stack and Coin Craze bonuses.

How do you trigger the bonus in Wicked Grin?

Land at least one FS or Super FS symbol on the bottom row. It expands to cover its reel, and the numbers it covers are added up to set between 5 and 30 free spins. A regular FS leads to Stash N Stack, with a Stash multiplying Coins on each reel; a Super FS leads to Coin Craze, with Coin Collectors.

When was Wicked Grin released?

Hacksaw Gaming lists the release date of Wicked Grin as 8 October 2026. It is an all-scatter slot with a black and white look, a host called Boney Bill, and features built around Wicked Grin symbols that turn reels into Coins and Multipliers when they land on the bottom row.

Can I play the Wicked Grin demo for free?

Yes. Hacksaw Gaming provides a free demo of Wicked Grin, and some casinos and review sites carry it too, subject to local rules. It lets you see how Multipliers boost Coins on converted reels and how FS numbers set the bonus length. Demo play is for adults aged 18 and over and does not predict real-money results.
