Pragmatic Play dives underwater with new slot Bubble Up!
Pragmatic Play has sent players back beneath the waves with Bubble Up!, a new slot that swaps the studio’s usual wild-multiplier formula for a grid full of drifting cash frames. It’s a cheerful, cartoonish addition to the underwater slot subgenre, and one built around a fairly unusual collector mechanic rather than the tumbling wilds the developer is best known for.
What’s been released
Pragmatic Play has released Bubble Up!, a new aquatic slot where players can win prizes of up to 10,000x their stake. The game is set against a sunlit coral reef, with a smiling octopus character presiding over the action from atop an underwater monolith. It plays out on an unusually large grid for a Pragmatic Play title, with 6 reels, 6 rows, and 40 paylines, giving the reels plenty of room for the game’s central money-symbol mechanic to develop. Betting flexibility is generous too, with stakes running from a minimum bet of 0.2 up to a maximum of 240, which can be increased to 360 using the Ante Bet.
How it plays
The core hook is the Frame Feature. A Frame Feature can produce one or two frames on the grid, awarding all the cash prizes for every Money Symbol that lands in a frame, with a frame appearing randomly on base spins and guaranteed on every Free Spin. Frames themselves vary in size, with random frames sized from 2×2 up to 6×6 appearing on the grid, and any money symbols inside a frame added together and paid. Things get more interesting when two frames land at once: if two frames overlap, money symbols in the overlapping area receive a random multiplier of x2, x3, x5, x8 or x10.
Money symbols themselves carry a wide spread of potential values, with money symbols carrying values from 0.5x up to 10,000x the base bet, including Mini, Minor, Major, Grand and Maxi tiers. The regular paytable is more modest, with lower-paying symbols returning between 2.5x and 3.75x the bet for a six-of-a-kind win, while the higher-paying fish and seahorse symbols pay between 3.75x and 25x, and notably there are no Wild Symbols, though Scatter Symbols can trigger the Free Spins.
Free Spins bring the growing-frame idea into sharper focus, offering a mini-game of modifier choices and expanding frames to keep bonus rounds varied, alongside a Feature Buy option and Special Bets for players who want to adjust their route into the bonus. Pragmatic Play has set the headline RTP at 96.52%, though as with many of its releases, operators can also configure lower-return versions, so it’s worth checking which model a given UK casino has live before spinning.
Where it fits
Bubble Up! lands in a crowded corner of the slot market: underwater themes are a well-worn setting, and reviewers have already drawn comparisons to other collector-style aquatic titles on the market. What sets it apart from Pragmatic Play’s recent output is the shift away from wild-driven multipliers towards a grid-based collection system, giving it a different rhythm to sit alongside the studio’s tumbling-reel favourites. For UK players, it’s another example of Pragmatic Play’s steady release schedule, which continues to lean on strong visual polish and layered bonus mechanics to keep its catalogue feeling fresh even within familiar themes. Expect it to appear across UK-licensed casino lobbies carrying Pragmatic Play content in the coming days, sitting alongside the provider’s wider library of high-volatility slots.
