Wicked Grin

Hacksaw Gaming's Wicked Grin is a high-volatility video slot played on a 5×5 grid. Scatter pays replace standard paylines, and the RTP is set at 94.32%. Players can select stakes from €0.10 to €100 per spin, with a top prize of 10,000x the bet available in every game mode. The feature set consists of Wicked Grin Coins, multipliers, and 2 bonus rounds, all presented through an old-school casino theme led by Boney Bill.

Gameplay Features and Bonuses

Wicked Grin uses a 5×5 grid with scatter pays, so there are no traditional paylines. The game has an RTP of 94.32% and is highly volatile. Bets range from €0.10 to €100 per spin. The maximum win reaches 10,000x the bet across all game modes.

Wicked Grin Coin: A Wicked Grin Coin on the bottom row expands across its reel after wins pay. Each position then becomes a Coin or Multiplier. Coin values depend on their type:

• Bronze: 1x to 4x
• Silver: 5x to 9x
• Gold: 10x to 50x
• Diamond: 100x to 500x

Epic Wicked Grin Coin: This stronger variant expands its reel and activates all other Wicked Grin symbols already on the grid. Only 1 Wicked Grin type can appear per reel.

Multiplier: Values range from 2x to 20x. A Multiplier adds its value to Coins above it on its reel and eligible Coins on adjacent reels. Multiple values apply one at a time, and Multipliers cannot appear on the top row.

FS Scatter: An FS Scatter on the bottom row expands across its reel, with each covered position worth 1, 2, or 3 Free Spins. The combined values award 5 to 30 spins and activate Stash N Stack.

Super FS Scatter: This icon follows the same principle as the Scatter but activates Coin Craze instead. Its values also provide 5 to 30 initial Free Spins. FS and Super FS icons cannot appear together.

Stash N Stack: Each reel starts with a 1x Stash multiplier. A Wicked Grin expansion applies that multiplier to all Coin values on its reel, after which the Stash rises by 1 for the next spin. Additional FS Scatters award 5 to 15 more Free Spins each, up to 30 extra spins.

Coin Craze: Each reel has a Coin Collector that stores Coin values from Wicked Grin expansions. Multipliers affect eligible Coins and saved Collector totals. Once the bonus ends, all 5 Collector values combine, and the bet applies to the result. Extra Super Scatters provide 5 to 15 more Free Spins each, up to 30 extra.

FeatureSpins and Bonus Buy: 4 paid options provide faster access to special mechanics:

• Bonus Hunt FeatureSpins: 3x bet, 5x higher bonus chance
• Grinny FeatureSpins: 50x bet, at least 1 Wicked Grin per spin
• Stash N Stack: 80x bet, at least 5 Free Spins
• Coin Craze: 200x bet, at least 5 Free Spins

Special-symbol restriction: FS symbols and Wicked Grin icons cannot appear on the grid at the same time.

Design and Soundtrack

Wicked Grin puts a sinister spin on vintage cartoon art. Boney Bill stands beside the 5×5 reels with an enormous grin and hollow red eyes, which gives the otherwise playful presentation an eerie edge. The dark circular backdrop contrasts sharply with colorful grapes, watermelons, cherries, bells, sevens, and card suits, so the grid remains easy to read. Bonus rounds swap the circles for a checkerboard backdrop and establish a noticeable visual change. The audio follows the same mischievous tone, with retro-style effects and energetic cues that become more prominent during feature events.

Other slots that have a similar visual and theme approach are Langley Street 23 by ELK Studios and Bloody Mary Pray for Prey by Peter & Sons.

The Bottom Line

Wicked Grin gets much of its identity from the expanding Wicked Grin symbols, Coin values, and multipliers, though the base game can feel restrained when these figures remain scarce. Stash N Stack adds reel-specific multipliers that rise throughout the bonus, whereas Coin Craze offers the stronger feature through persistent Coin Collectors. Scatter pays and cascades add more activity between bonus rounds. FeatureSpins and direct bonus purchases provide alternative access to the main mechanics, and the 10,000x maximum win remains possible in every mode.
