Wicked Grin

Wicked Grin is a black-and-white skeleton slot from Hacksaw Gaming, released on 8 October 2026. Its host is Boney Bill, a grinning skeleton in a red bow tie and white gloves who looks like he stepped out of a 1930s cartoon, and his huge toothy smile is the symbol that drives the whole game. That spooky-but-playful style makes it a natural pick for Halloween. The game uses a 5x5 grid with All-Scatter wins, the RTP is up to 96.27%, the volatility is medium (3 out of 5) and the maximum win is 10,000x the bet.

A Cartoon Skeleton In Black And White

The whole screen is drawn in grey tones with a hypnotic spiral in the background, and colour appears only on the symbols and on Bill’s red outfit. The reels are filled with classic fruit machine icons: blue sevens, golden bells, red cherries, purple grapes and green watermelons, plus the four card suits as low-paying symbols. In the bonus rounds the backdrop changes to a glowing checkerboard floor, as if the show moved onto an old vaudeville stage, and red theatre curtains frame the intro and result screens.

All-Scatter Wins With Tumbles

There are no paylines. A win needs 6 or more matching symbols anywhere on the grid, and the pay grows in seven steps up to groups of 17 or more. The four card suits pay up to 25x the bet for 17+, the fruits pay between 50x and 75x, and the best symbol pays 100x for the largest group. After every win the winning symbols disappear and new ones tumble in, so one spin can bring several wins in a row.

Expanding Wicked Grin Coins

The Wicked Grin symbol is Bill’s grinning skull on a silver coin. When it lands on the bottom row, it expands up the whole reel after all wins are paid, and every symbol on that reel turns into a Coin or a Multiplier:

• Bronze Coins are worth 1x to 4x the bet, Silver Coins 5x to 9x, Gold Coins 10x to 50x and Diamond Coins 100x to 500x;
• Multipliers of x2, x3, x4, x5, x10 or x20 boost every Coin above them and the Coins on the neighbouring reels in the rows above.

The rarer Epic Wicked Grin goes one step further: when it expands, it also makes every other Wicked Grin symbol on the grid expand from its current spot, even if it is not on the bottom row.

Spreading FS Symbols

The bonus is triggered in a similar way. When an FS or Super FS scatter sits on the bottom row, it spreads across its whole reel, and every position it covers shows a number of 1, 2 or 3 free spins. These numbers are added together, so one bonus can start with anything from 5 to 30 free spins. Up to two such scatters can be on the grid at once, and new expanding scatters in the bonus add 5 to 15 more spins each.

Stash N Stack Or Coin Craze

A normal FS symbol opens Stash N Stack. Above each reel sits a Stash multiplier that starts at x1. When a Wicked Grin expands on that reel, the Coins are multiplied by the Stash, and the Stash then grows by 1 for the next spin, so the same reel keeps getting stronger.

A Super FS symbol opens Coin Craze. Here each reel has a Coin Collector on top. Every time a Wicked Grin expands, all Coin values on that reel are saved in its collector until the end of the round, and Multipliers boost both the Coins and the saved values on that reel and the reels next to it. At the end, all collectors are added up and paid in one sum.

Bonus Buy Menu

Four options are available where bonus buys are allowed. BonusHunt FeatureSpins cost 3x the bet and make the bonus five times more likely, and Grinny FeatureSpins cost 50x and guarantee at least one Wicked Grin symbol on every spin. Stash N Stack costs 80x and Coin Craze costs 200x the bet. In the version we played, the RTP of all four options stayed between 94.24% and 94.41%, very close to the base game, so buying does not cost you extra return. Both bonus rounds are marked as high volatility in the menu, while the BonusHunt mode is rated very high.

Seven Spins Of Coin Craze

We set the demo to €2 per spin and bought Coin Craze for €400. A Super FS coin spread up the fourth reel, and the round started with 7 free spins. The first spins were quiet, with only small wins of 20 cents, but then a Wicked Grin on the bottom row filled two reels with Coins and an x3 Multiplier, and the collectors jumped to 3x and 6x. A few spins later another big expansion pushed them to 26x, 32x and 45x, and the last reel reached 58x. When the collectors were paid out, the counter climbed through a Big Win, and the round ended at €359.40, not far from the price of the bonus.

RTP And Betting Range

Hacksaw offers Wicked Grin with an RTP of 96.27%, and also with lower versions at 94.32%, 92.28% and 86.28%. The demo we played ran the 94.32% version, so it is worth checking the game info at your casino. The volatility is medium, the maximum win of 10,000x can be reached in all game modes, and the demo allows bets from €0.10 to €2,000.

Our Take

Wicked Grin is a stylish change from Hacksaw’s colourful slots. The black-and-white cartoon look and the creepy grin give it a nice Halloween flavour, the expanding Coins make every bottom-row skull exciting, and the Coin Collectors in Coin Craze build up a clear, satisfying payout at the end.
