Grinning Harvest is the latest 3×3 high-volatility slot from Trusty Gaming, providing a spooky cinematic Halloween setting along with action-packed Hold-to-Win mechanics and a mighty max win of 15,000x. A game made that’s simply designed for seasonal fun with a powerful combination of glowing pumpkins, value-boosting multipliers and instant-collect features that make for quick reward hits on any device.
The reel set is in a spooky harvest field with Pumpkin symbols of different random cash values that you can collect, including Mini, Minor, Mega, and Grand prizes. Landing Pumpkins next to the Collector Vault adds their visible values to the Vault, which is then paid out at the end of the Free Spins. And that’s when things really heat up: Big Skull and Multiplier Row can turn even small wins into gigantic payouts!
With a 96.26% / 94% RTP, stakes from $0.10 to $50, and the slick Halloween theme, Grinning Harvest has been developed with casual punters as well as high-rollers in mind. The game is the fifth instalment of the Trusty Gaming series and serves to complement the studio’s commitment to building high-performing games, with eye-catching visuals while maintaining the accessibility of gameplay and real win potential. Enter the moonlit pumpkin field, and you may just discover every spin can lead to a frighteningly big win.
The bonus starts when you land:
Pumpkin on reel 1, Collector Vault on reel 2, and Pumpkin on reel 3, all in the same spin (outer reels + centre reel).
The Multiplier Row is an extra row above the main 3×3 grid that appears during the Bonus Game. It can display:
multipliers (boosting values below them for that spin), skulls (teasing/trigger logic), or empty spaces.
The Big Skull is a bonus-only enhancement tied to the skull symbols in the top row. If you hit full set of skulls in one spin, it can apply a large multiplier to all Pumpkin and Collector Vault values on the grid for that spin, which is how the values can turn into a much larger prize.
Hold-to-Win Bonus Game uses a collect-and-clear loop: when a Pumpkin lands, its value is transferred into the Collector Vault and the Pumpkin disappears. The Collector Vault(s) stay on the middle reel (up to 2–3 Collector Vaults can remain), and the spin counter resets whenever a Pumpkin or Collector Vault appears.
