How Does the Fatter Fish Festival Slot Work?

Before the player starts playing any online casino games, it’s important that they understand how each of these games works. Knowing how the different game elements work together could be key to maximising slot payouts.

In this online slot game, you can open the game help files by selecting “i”. This will open a game menu with the paytable, description of the features, and the basic rules for the Fatter Fish Festival.

Once the player is familiar with the gameplay, they can start a game by confirming their wager in the Stake menu. Bets start from as little as $0.20 and go up to $40 per game. When the reels start to spin, the goal is to land three to five matching symbols on one of the game’s 20 paylines, starting from the leftmost reel. The game’s various features can assist or enhance this symbol matchmaking process.

Fatter Fish Festival Game Features

Fatter Fish Festival isn’t packed with bonuses. Rather, this fishing-themed slot has one feature packed with bonuses.

Fatter Fish Festival Extra Spins Feature

To activate the extra spins feature, the player needs to land a scatter symbol on the reels that unlocks one of the treasure chests (or multiple treasure chests) above the reels.

When this feature is triggered, it begins with 10 spins. Each spin of the reels will reveal fish symbols with cash payouts. These rewards can vary from 0.2x to 1,000x the player’s wager. However, a Collect symbol must land for the player to receive these rewards.

The bonuses in the treasure chests vary depending on where the scatter lands on the reels. Here are the difference enhancements that the player can expect:

  • Reel 1: An activating scatter will unlock extra spins with a multiplier enhancement. This boosts payouts by up to 5x.
  • Reel 2: An activating scatter will unlock extra spins with an adder enhancement. Boosts cash values by adding up to 5x the stack to fish symbols.
  • Reel 3: An activating scatter will unlock extra spins with the Golden Egg feature. Activate all bonus effects.
  • Reel 4: An activating scatter will unlock extra spins with the Symbol upgrade. Adds extra fish symbols to reel positions without fish symbols.
  • Reel 5: An activating scatter will unlock extra spins with the Respin upgrade. When a Collect symbol lands, all non-fish, non-Collect symbols will respin, which could reveal more fish symbols.

Except for the Golden Egg feature, all of these effects can trigger at the same time, resulting in stacking benefits during the extra spins feature. The Golden Egg feature is excluded because it activates all of these effects together.

Fatter Fish Festival Slot Bonuses and Jackpots

Fatter Fish Festival doesn’t have a jackpot prize, but there are bonuses waiting to be won courtesy of the extra spins feature. Depending on which effects a player unlocks, this feature could end up paying out as much as 6,000x the player’s wager.

Fatter Fish Festival Slot Graphics and Design

This Microgaming slot game delivers high-quality, stylised visuals and audio.

The game’s visuals are presented in a style that blends digital painting with a cartoon-like appearance. The backgrounds are surprisingly detailed, depicting underwater cliffs, seaweed, bubbles, and silhouettes of fish swimming by. The reels similarly offer a great deal of detail. The game’s symbols lean more towards the cartoonish, but are still highly appealing.

The game’s soundscape starts off with a Western-style banjo tune that adds life to the game, even when the player hasn’t yet started spinning the reels. The game’s sound effects tie in with the game’s fishing theme and include popping bubbles, spinning fishing reels, and quick banjo strums, all of which highlight the activation of key events during the game.

Fatter Fish Festival Slot Symbols

The reels of the Fatter Fish Festival slot game could unveil a variety of themed and regular slot symbols.

The regular slot symbols are the 10, J, Q, K, and A, and all pay a maximum of 1x the player’s wager. These symbols are followed by the themed symbols. These are the tin of worms, a hook, a fishing reel, a fishing boat, and the fish wild. These symbols pay 2x, 3x, 4x, 5x, and 10x the player’s wager, respectively.

Other special symbols are the fisherman scatter that appears during the base game, as well as the fish and collect scatters that appear during extra spins.
