Ladies and gentlemen, you join us for a milder form of slot review, one that’s smoother, more refined, and containing a certain level of class that beats all others. For this review, we present Bubble Up! by Pragmatic Play, an underwater-themed animal slot that, in most other cases, would take us on a Jules Verne-style voyage into the depths of the ocean to present it. However, due to a misunderstanding, our entire budget was allocated to this gentleman’s club lounge and bar, where we announced the game’s release.
Joining me for a high-priced cigar and glass of champagne is David Slottenborough, who shares his insight and experience of playing Bubble Up! for real money. Stick with us to learn about the game’s performance, features, and potential payout. Plus, you'll find which of the best casinos are hosting this game in its real-money format.


You join me here in the warm, cozy surroundings of the Gentlemen’s Club, far from the waters of the Pacific Ocean, where death is a near certainty. And where I can comfortably order a Lustau Sherry without having to wear any scuba diving gear. From the comfort of this leather wingback armchair, I shall be playing Bubble Up! by Pragmatic Play, cheers.
The Bubble Up! slot's RTP is 96.52%, and it plays at high volatility. Players may experience a low hit rate, leading to periods of play with few to no wins. The appeal of such a game comes from its ability to pay out high wins at random, which some players see as a worthy reward for the strong patience it requires.
The slot has a 6x6 grid layout with up to forty paylines. Winning is formed by aligning matching symbols across adjacent reels. The highest single win is 10,000x your bet. The cost of play ranges between $0.20 and $240, but the max bet is subject to change depending on the casino you play in. If you can play the max bet, the total jackpot becomes $2,400,000!
While playing Bubble Up! you may come across a section of special features and symbols that lead to more payouts, if you’re lucky. These include Money symbols, Instant Prize Jackpots, there is the Frame Feature, the Free Spins bonus, and you have the Buy Feature, and the Special Bets option.
Bubble Up! is one of those cute, run-of-the-mill slots that you will have seen a hundred times before. Sadly, the same can be said of the performance, but it’s nice to see Pragmatic Play adding more to their game than usual. The free demo is available for you to test yourself, and remember, no bubbly when playing. Chin-chin.
Here, within the tropical coastal beaches bordering the Pacific Ocean, a flurry of sea life has inhabited the Bubble Up! slot as their home, which is now a thriving ecosystem of shellfish, seahorses, and fish. To see this hive of aquatic creatures in their peak mode, we set the bet to $2 per spin and begin playing the slot game.
The first spin presents a $3 win, which is followed by $4.50 three spins later. These two wins are all that land from the first ten spins. The game’s flow is encouraged by cheerful Caribbean-style music, which makes the low hits manageable, for now.
Into the next ten spins, the wagering is raised to $3. The increase brings a win of $2.25 on the fourth spin. Sadly, the sea life aren’t helping to produce anything more than this, and the round of ten spins ends with a worse hit rate than the first round of play. However, with the odds now stacked in favor of a win being due, I raise the bet to $4 per spin and make it one last round of play. It takes till spin five to get a return, which pays out $18, the largest single win so far.
Alas, this was to be the only win of that round. Sadly, the experience was only reflective of my luck, perhaps. The hit rate, however, was very low throughout, displaying signs of how a high-volatility slot performs, given there was only one notable large win.
