Double Bubble Graphics and Sound

Double Bubble Slot is love at first sight for punters looking for a refreshing spin session. It has a pulsating ambience that comes alive out of a green background. The game is available in full HD and the animations are top class. Double Bubble Slot has amazed players for long due to its smooth and textured animations. After the recent upgradation, Double Bubble has become more vibrant with more visual fonts and a completely new background. The sound effect is apt and suits the overall environment. The symbols are designed and spaced in a very comfortable manner, and it looks good on any device size.

Double Bubble Gameplay, Volatility, RTP, Max Win

There are 5-reels and 3 rows in Double Bubble slot game. The game carries a max payout of 30,000x of coin size, yielding a maximum cash value of £90,000. The slot is progressive in nature and has paid out impressive amounts in the past. In total, the slot has generated more than £8.5 million of prize money to lucky punters since its launch. After a recent upgrade of its jackpot network, the jackpot amount usually triggers in the range of £30,000-£50,000. There are 20 paylines and it forms quite an interesting pattern. The volatility is extremely balanced and stays in the domain of medium to high. Double Bubble Slots pays out in frequent intervals compared to many other fruit-based slots.

However, apart from its grand jackpot, Double Bubble Slot has very good volatility that suits casual punters, who are looking for frequent hits. In our tests of 300 spins in the game, we found a hit rate of 14% high wins and 19% low-medium hits. We kept changing the bet amount but there was no noticeable difference in the outcomes. This makes it less attractive for high-rollers since the RTP is capped at 96%. If you are looking for some quick brownie points, then Double Bubble Slot is a refreshing destination where you can reap some quick returns.

Double Bubble Slot received its own local jackpot network in January 2017, becoming one of the few brands of Gamesys to do so. The Double Bubble Jackpot has been triggered quite often, averaging 1 trigger every 2-3 months. The jackpot feature was a quick success and it pooled in many top gamers. Company representatives have confirmed plans for the upgrade of the jackpot amount to £100,000.

Conclusion

Double Bubble Slot is one of the oldest online slots in the iGaming industry. The game has won player’s trust for its simple mechanics and light-hearted graphics. It is one of Gamesys’s flagship launches and it carries the mojo to compete with slots of Microgaming and NetEnt. The full HD graphics, a good frequency of wins, a new jackpot feature, and super smooth mobile gaming are some of the major selling points for the brand. Double Bubble may have an edge in its design and bet range, but it loses some of its sheen with the lack of variable RTP for high rollers and fewer bonus rounds. The house edge of 4% is a bit too steep for its niche. The gameplay is just average and it lacks any unique feature.

Double Bubble Slot was highly popular during its hay days but it hasn’t been able to innovate itself to suit the 21st century punting needs. The lack of exciting bonus rounds took away a lot of young punters away from the brand. The developers have included some changes in its façade with the launch of its new mobile version, but it does need more than just bandage therapy.

However, Double Bubble remains a class apart when it comes to graphics and sound. We recommend this game to casual punters who want a simple slot with good hit rate and vibrant graphics. For serious games, looking for special features, there are other classics in the fruit slots genre.
