Slot Overview

Wicked Grin is a high-volatility video slot from Hacksaw Gaming, set across a 5×5 grid with scatter pays instead of fixed paylines. The RTP stands at 94.32%, and stakes range from €0.10 to €100 per spin. The character Boney Bill brings the classic casino theme, along with Wicked Grin Coins, multipliers, and 2 separate bonus rounds. The highest possible award equals 10,000x the stake across all game modes.

Slot Theme

Wicked Grin Theme

Wicked Grin adopts a dark take on vintage cartoon art, with a grinning skeletal character beside the 5×5 grid. A charcoal circular backdrop places greater focus on the colourful fruit, bells, sevens and card suits.

Bonus rounds replace this background with a checkerboard pattern, which gives these features a distinct visual identity. Retro sound effects complement the mischievous theme, and more energetic audio cues accompany bonus events.

Slot Bonuses & Features

Wicked Grin Gameplay

Wicked Grin bases much of its feature set around special symbols that can transform complete reels and modify Coin prizes.

Coin symbols and reel effects: A standard Wicked Grin Coin can activate from the lowest row after a win. It covers its full reel and replaces each spot with either a Coin or Multiplier. 4 Coin tiers determine the possible values:

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

The Epic Wicked Grin Coin has an additional effect. Once activated, it covers its own reel and triggers every other Wicked Grin icon visible elsewhere on the grid. Each reel permits only 1 Wicked Grin type.

Wicked Grin Coin Multipliers

Multiplier symbols: These carry values from 2x to 20x and never occupy the uppermost row. Their value is added to applicable Coins above them on the same reel, plus qualifying Coins on either neighbouring reel. Several Multipliers can affect a Coin, with each value added separately.

Free Spins triggers: 2 Scatter types lead to separate bonus rounds. Each must appear on the lowest row before it can cover its reel. The revealed positions show awards of 1, 2, or 3 Free Spins, which combine into an initial total of 5 to 30.

Wicked Grin Scatter

The regular FS Scatter starts Stash N Stack. Each reel enters the bonus with a 1x Stash multiplier. Whenever a Wicked Grin Coin expands, all Coin values on that reel receive the relevant Stash value. That multiplier then rises by 1 ahead of the next spin. Further FS Scatters award 5 to 15 spins apiece, subject to a maximum of 30 additional Free Spins.

The Super FS Scatter starts Coin Craze. Here, every reel has its own Coin Collector. Coin rewards from Wicked Grin expansions accumulate inside the relevant Collector, and Multipliers can modify eligible Coins as well as stored Collector amounts. Once the round finishes, the values from all 5 Collectors form one total, to which the bet is then applied. Further Super FS Scatters provide 5 to 15 additional spins each, up to 30 in total.

Wicked Grin Buy Feature

Regular FS Scatters and Super FS Scatters cannot occur together. FS figures also cannot share the grid with Wicked Grin icons.

Paid feature options: 4 choices alter access to the slot’s special mechanics.

  • Bonus Hunt FeatureSpins cost 3x the bet and increase the bonus chance by 5x.
  • Grinny FeatureSpins cost 50x and guarantee at least 1 Wicked Grin on every spin.
  • Stash N Stack costs 80x and starts with at least 5 Free Spins, whereas Coin Craze costs 200x and also starts with a minimum of 5.

Conclusion

Wicked Grin places its greatest award potential in its Coin mechanics and multipliers, with Stash N Stack and Coin Craze as the main attractions. The former raises reel-specific multipliers as the bonus progresses, whilst the latter stores Coin values across 5 Collectors.

Base play may feel subdued when special symbols appear less often, although scatter pays and cascades add some variety. FeatureSpins and bonus purchases offer quicker routes to special features, and every mode retains access to the 10,000x maximum win.
