Fish Boom in the United Kingdom

What is the Fish Boom Game?

The Fish Boom Game is an arcade instant title from iNOUT released in november 2025. Instead of reels and paylines, you get a 4×5 grid with 20 cells and a single hook that drops on one of them each round. It is not a slot and not a crash game, but a fast click-and-drop format where one move settles the result.

Features such as the Bet Bar, Free Spin Mini-Game, TNT Spin blasts and boosters can all change the outcome of a round in Fish Boom and push wins towards the £20,000 ceiling.

How to Play Fish Boom

Fish Boom Online keeps the controls light. Pick a stake in pounds, press spin and watch the hook fall. It locks onto one of the 20 cells and the symbol in that cell sets your payout, booster or feature. The rules are easy to grasp after a few rounds, which suits short sessions on phone or laptop.

Game Mechanics

The core mechanics are simple, but they leave room for strong swings. Key points are:

• Each round starts with stake selection and a single spin; Auto Game can repeat this for a chosen number of rounds.
• The hook lands on one of the 20 cells; that symbol decides the win, multiplier or feature trigger.
• Every spin fills the Bet Bar; when full, it launches the Free Spin Mini-Game.
• The mix of high volatility, dynamite symbols and Big Fish connections creates a constant balance between risk and big-win potential.

Every hook drop carries a visible risk–reward trade-off, which is the main appeal of Fish Boom.

Special Features

This is where the Fish Boom shows its most exciting moments.

• TNT Spin: Dynamite makes the cell explode and pay out, sometimes boosting the multiplier for the round.
• Big Fish: When the hook hits Big Fish, it links two cells and combines their multipliers into one stronger payout.
• Bet Bar & Free Spin Mini-Game: The Bet Bar fills with bubbles on every spin; a full bar opens free rounds with the same grid but extra boosters.
• Turbo and Auto Game: Turbo mode and automated spins let players push through many drops quickly, ideal for testing the game flow.

Together these tools make Fish Boom feel closer to an arcade cabinet while still fitting into modern lobbies.

RTP and Volatility in Fish Boom

Fish Boom comes with an RTP of 96.3%. In real sessions the balance can swing sharply because multipliers and features often cluster together. The high volatility means fewer regular wins but room for heavy spikes when the right symbols line up.
