Grinning Harvest Slot by Trusty Gaming
Step into a candlelit patch of pumpkins in Grinning Harvest, a 3x3 Halloween-themed slot with 5 paylines from Trusty Gaming. This eerie crowd-pleaser blends fast base-game action with a sticky Hold-n-Win bonus, a surprise Multiplier Row, and four in-game jackpot values that can show on Pumpkin symbols. Smooth animations, crisp audio, and a compact grid deliver quick-fire thrills on every spin.
How Grinning Harvest Plays
- Reels and lines: 3x3 grid with 5 paylines
- Theme: Spooky harvest, pumpkins, skulls, and vaults
- Volatility: 4/5 for punchy, high-octane sessions
- Wilds: Substitute for all symbols except Pumpkin and Collector Vault (base game only)
Instant Loot and Bonus Trigger Conditions
The core of Grinning Harvest is the Pumpkin + Collector Vault combo:
- Instant Loot (Base Game): Land a Pumpkin on reel 1 OR reel 3 with a Collector Vault on the middle reel (reel 2) to claim an instant cash prize.
- Pumpkin symbols can display values as play multipliers: 2x–10x, or Mini (25x), Minor (50x), Mega (100x), Grand (1000x).
- The Collector Vault gathers the values of all Pumpkins that land in the same spin. Each Vault collects independently.
- Hold-n-Win Bonus Trigger: Land Pumpkins on BOTH reels 1 and 3 plus a Collector Vault on reel 2 in the same spin to launch the Bonus Game.
Hold-n-Win Bonus: Sticky Vaults and Resetting Respins
During the Bonus Game, only Pumpkins and Collector Vaults appear:
- Triggering symbols lock in place and you start with 3 respins; any new Pumpkin or Collector Vault resets the counter to 3.
- Collector Vaults are sticky and can collect the values from Pumpkins multiple times during the bonus.
- Up to 3 Collector Vaults may land, and each Vault collects independently.
This setup creates a tense, escalating endgame where sticky Vaults keep cashing in, and new Pumpkins refresh your lifeline.
Multiplier Row & Big Skull Explained
When the bonus begins, the Big Pumpkin above the reels morphs into the Big Skull, revealing an extra row that can show:
- Multipliers (2x–5x): Applied to the symbol directly below. If the multiplier sits above a Collector Vault, it boosts the Vault’s value first, before the Vault collects other Pumpkins.
- Skulls: Land 3 small skulls to trigger the Big Skull gift — a powerful 3x–9x multiplier applied to all symbols on the grid for that spin.
- Spider web (empty): No effect.
This Multiplier Row adds a strategic layer, supercharging either the Vaults or the Pumpkins beneath it.
