Grinning Harvest
ABOUT THE GAME
Grinning Harvest is a spooky but fun 3x3 Halloween game with 5 paylines and a fascinating Bonus Game.
In the Base Game, a Pumpkin lands alongside a Collector's Vault for instant loot. Four mysterious Jackpots lurk in the shadows, waiting to award huge prizes to the luckiest players.
But the real madness begins in the Bonus Game with its Hold-and-Win mechanic—only Pumpkins and spooky Collector Vaults appear. Watch out for the extra row above the reels: it can bring juicy multipliers… or reveal three skulls for a terrifying grid-full boost.
Dare to enter and you could leave with a prize of up to 15,000x your bet (in the Bonus Game)... if the Pumpkin Guardian lets you out, of course.
FUNCTIONS
Pumpkin Symbols
The Pumpkin symbols are dynamic payout symbols that display cash values and can only appear on reels 1 and 3. The cash value shown on the symbol represents the actual payout that will be awarded if the Pumpkin is collected by the Collector's Vault. Pumpkin symbols can have values based on the following bet multipliers: 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 25x (Mini Jackpot), 50x (Minor Jackpot), 100x (Mega Jackpot), 1000x (Grand Jackpot).
Jackpot Coins: Mini (25x), Minor (50x), Mega (100x), Grand (1000x). They appear only on Pumpkin symbols.
Collector's Vault Symbol
The Collector's Vault collects Pumpkin values in all game modes and can only appear on reel 2. It only collects Pumpkin values that land on the same spin or subsequent spins after it appears. A new Vault on reel 2 follows the same rule: it does not collect Pumpkins that have already landed. If there are multiple Vaults on the second reel, each one collects independently. There is no interaction between them.
If the value of the Pumpkin or Vault symbols is too large to display in full, it will be shortened to two decimal places. The displayed value will always be the minimum amount you can win. The actual amount awarded may be higher, but never lower, than the displayed value.
For example: a value of 10,250,500 can be rounded down and displayed as 10.25M.
Hold-n-Win Bonus Game
It is triggered by Pumpkins on reels 1 and 3 and a Collector's Vault on reel 2. The Pumpkins and the Vault do not pay out in the Base Game if a bonus is won, but are carried over to the bonus. The Pumpkins are collected before the first bonus spin.
During the Bonus Game, only Pumpkins and Collector Vaults appear. The Vault remains fixed until the end of the Bonus Game, and more may appear (up to a maximum of 3). The free spins counter starts at 3 spins. Each new Pumpkin or Vault resets the counter to 3. The bonus ends after 3 consecutive empty spins.
Row of Multipliers and Great Skull
The Big Pumpkin above the reels becomes the Big Skull during the Bonus Game. An additional row appears above the reels. It can display multipliers, skulls, or empty symbols (a spider web).
Multipliers (2x–5x) are applied only to the symbol directly below it on the reel. If a multiplier appears above a Vault, it is applied first to the Vault's value before collecting Pumpkin values from other reels.
Skulls: A combination of 3 small skulls in the row triggers the Great Skull's gift: a (3x–9x) multiplier applied to all Pumpkin and Vault values on the playing field for that roll.
The empty symbol does not affect the reel below.
The theoretical return to player (RTP) for this game is 94.31%. The RTP was calculated by simulating 10,000,000,000 rounds.
