Double Bubble: A Guide to the Double Bubble Collection

The Double Bubble series has become one of the most recognisable collections of bubble-themed slot games in the UK. 

Originally created by Gamesys before the studio became Roxor Gaming and later joined Aristocrat Interactive, the online slot game series has expanded by introducing new mechanics while preserving the colourful style and accessible gameplay of the original title.

Each release builds on the same foundation rather than completely redesigning the gameplay. This has allowed the series to evolve while remaining familiar to players at Genting Casino who have enjoyed Double Bubble over the years.

In this article, we’ll be going through the following points:

• How the Double Bubble Series Has Evolved
• Double Bubble
• Double Bubble Colour Connect
• Double Bubble Incredibet
• Double Bubble Fizz
• Double Bubble Cash Wall
• Double Bubble Series Comparison

How the Double Bubble Series Has Evolved

Every title shares the same retro-inspired presentation, but each introduces a feature that gives it its own identity.

Players exploring different online slots can see how the series gradually expands from the original Bubble Line mechanic to colour-based multipliers, progressive bonus systems and persistent collection features. Rather than replacing the original gameplay, every release adds a fresh layer while keeping the familiar Double Bubble style.

Double Bubble

The original Double Bubble established the formula that the rest of the series follows.

Its signature Bubble Line collects qualifying bubble-covered symbols beneath the reels. Winning combinations formed on this additional line receive multipliers before prizes are awarded. The game also includes the Bubble Pop Bonus, an interactive pick feature that awards instant prizes, making it the foundation for every later entry in the collection.

Double Bubble Colour Connect

Double Bubble Colour Connect introduces a new Colour Connect mechanic while retaining the familiar Bubble Line gameplay.

During random spins, the reel colour changes from its default appearance to one of several colours. Cash Bubble symbols that match the active reel colour receive multipliers before they are collected by the Collector symbol. The game also includes Free Spins, during which the Colour Connect feature activates on every spin, making the bonus round feel different from the base game.

Double Bubble Incredibet

Double Bubble Incredibet keeps the familiar Bubble Line and Bubble Pop Bonus while enhancing the original gameplay.

Instead of introducing an entirely new mechanic, this version focuses on increasing multiplier potential through the Incredibet feature. The overall structure remains familiar, making it an easy transition for players who already know the original game while adding a refreshed feature experience.

Double Bubble Fizz 

Double Bubble Fizz represents one of the biggest gameplay changes in the series.

It introduces Bubble Wins alongside the Super Bubble Bonus. During the feature, Bonus symbols merge together into a growing Super Bubble that expandsacross a dedicated grid. The bonus continues while new Bonus symbols join the bubble, creating a progressive feature unlike the earlier games in the collection.

Players interested in feature-driven jackpot slots will notice how this title focuses more on progressive bonus development than the original releases.

Double Bubble Cash Wall

Double Bubble Cash Wall introduces a persistent Bubble Grid known as the Cash Wall.

Cash value bubbles and Free Spins bubbles move into the grid during gameplay, where several different Collector symbols gather rewards using unique collection patterns. 

The Free Spins feature carries the Cash Wall forward from the base game and introduces Collecting Pipes that store additional rewards throughout the bonus round. This persistent collection mechanic gives the game one of the most distinctive gameplay styles in the series.

Genting Casino Tip: When exploring a game series in an online casino, take a few moments to learn what makes each title unique. Although the Double Bubble games share the same overall theme, understanding their different mechanics helps you appreciate how the series has evolved over time.
