Fat Fish Festival Game Features

The Fat Fish Festival slot game offers regular wins and bigger moments reserved for the Bonus Feature.

Fat Fish Festival Wild Symbol Feature

Wild symbols are wooden fish cutouts with the word wild covering them. These substitute for all paytable symbols to help create or extend winning combinations across paylines. Further than that, wilds can also create their own standalone wins when 3-5 wilds land on the reels.

Fat Fish Festival Bonus Feature

The Bonus Feature on this DGCGameflex slot game triggers at random whenever a Fisherman scatter appears on the reels and unlocks the chests above it. Each reel has a locked chest, holding one of five unique feature enhancements. It’s also possible to unlock multiple enhancements at once.

During bonus spins, Fish symbols carrying values between 0.20x and 1,000x the bet appear alongside upgrade symbols, which can boost their active enhancement. Any Fisherman symbol landing along with Fish symbols will collect all Fish values in view, except on a respin, where all values are collected once respins end.

The standard trigger with one unlocked enhancement awards 10 starting spins, with each additional unlocked enhancement awarding an extra three spins. Non-active enhancements can also be randomly unlocked mid-feature, but each chest can only activate once.

The five enhancements are:

Fat Fish Festival Bonus Feature Red Chest (Reel 1)

Unlocks the Multiplier Enhancement starting at 2x and increases by 1x up to a max of 5x when each X symbol lands on the reels. Multipliers are applied to every Fish symbol value or upgraded symbol collected by the Fisherman scatter.

Fat Fish Festival Bonus Feature Green Chest (Reel 2)

Unlocks the Adder Enhancement, adding the value on the chest to every Fish symbol value or upgraded symbol during a Fisherman collection. The value on the chest starts at 1x your bet, adding 1x the bet for each plus symbol landing on the reels. The chest value is capped at 5x the bet.

Fat Fish Festival Bonus Feature Blue Chest (Reel 4)

Unlocks the Symbol Upgrade Enhancement, adding a value to the playing card ranks landing on the reels. Each Arrow Up landing on the reels includes the next card rank to receive a value, moving from 10 through A. These values are collected by the Fisherman symbol, along with Fish and upgraded symbols.

Fat Fish Festival Bonus Feature Purple Chest (Reel 5)

Unlocks the Respin Upgrade Enhancement, adding a respin chance to each collection during the feature. Each new heart symbol landing on the reels adds an extra respin to the mechanic. When a Fisherman lands for a collection, it and all Fish and upgraded symbols lock in place while the rest of the positions respin until no respins are left or the grid fills with collectible symbols.

Fat Fish Festival Bonus Feature Golden Chest (Reel 3)

Activates all enhancements at once, with each chest spinning before the feature starts for a chance to increase their base values. Unlocking the Golden Chest also starts the feature off with 19 bonus spins.

Fat Fish Festival Slot Bonuses and Jackpots

This online casino game doesn’t include any traditional jackpot mechanics, but with all the enhancements available in the Bonus Feature, it isn’t even necessary. During the Bonus Feature, you can collect impressive bonus prizes. And with the right combination of unlocked enhancements, you can push your wins up in no time. If luck is on your side, you could win the top prize of a generous 6,000x your base bet.

How To Win the Fat Fish Festival Slot

The best slot strategy to keep in mind is to cover basic payline wins between feature hits. For these, you’ll need to line up three or more matching symbols on a payline, starting on reel one and moving from left to right. Wild symbols can also help you unlock winning combinations.

You can also win prizes by activating the Bonus Feature. Line wins and additional prizes are up for grabs during this feature.

Fat Fish Festival Game Graphics and Design

This fishing-themed slot features crisp colors and beautifully illustrated elements, ranging from fishing paraphernalia to striking sunset landscapes stretching across the open water. Most of the interface sits in deep blue, where silhouettes of underwater flora and fauna ebb and flow across the screen. The reel grid is framed in wooden panels, with colorful chests strapped with gold chains and locks resting above each reel. A classic banjo-and-fiddle country music anthem and sunset keep this game’s fisherman company during each spin of the reels.

Fat Fish Festival Slot Symbols

The paytable features illustrated fishing elements as the high-paying symbols, with themed card ranks filling out the lower tier. A can of worms, fishing hook, fishing rod, and the boat pay up to 2x, 3x, 4x, and 5x the base bet for five matching symbols, with the fish wild taking the top-paying spot at 10x the bet. Card ranks 10 through A pay a top prize of 1x on the lower end.

Additionally, Fisherman scatter symbols also unlock the game’s top prize of 6,000x your wager if you get lucky and land five matching scatter symbols. During the Bonus Feature, different types of fish scatters can also offer cash prizes when the Fisherman scatter collects them.
