How this slot Pays

The slot runs on a 6×6 grid with 40 paylines. Regular symbol wins pay 0.25x to 25x your stake for 3-6 of a kind – colorful fish, seahorses, shrimp, shells, starfish. No wilds. Instead, blowfish money symbols land with values from 0.5x to 15x, plus four named jackpots (Mini 20x, Minor 40x, Major 80x, Grand 200x) and a Maxi jackpot ranging 400x to 10,000x your stake.

Frames appear randomly during base game spins. They collect all money symbols inside and land in sizes 2×2 up to the full 6×6 grid. Land two frames on the same spin and they can overlap – money symbols in the overlap zone get boosted by a random multiplier of x2 to x10 before payout. This overlap mechanic is where base game tension lives.

Free Spins / Modifiers

Land 3, 4, 5, or 6 scatter symbols and you trigger 6 free spins – the scatter count doesn’t increase the spin grant, it determines how many modifiers you unlock instead (1, 2, 3, or 4). Before the bonus starts, a pick game reveals 8 coins. You match pairs until you hit your modifier limit. Modifiers boost money and scatter symbol frequency on the reel strips, plus guarantee a 3×3 minimum frame size and 2 frames per spin.

During the bonus, one frame is guaranteed each free spin by default. Collect 3 scatters and the minimum frame size upgrades: 2×2 → 3×3 → 4×4 → 5×5 → 6×6. Each upgrade also awards +2 extra free spins, applied on the next spin. Scatters collected during the feature expand the frame floor and add spins – the feature can grow teeth fast.

Ante Bet / Bonus Buy Menu

Feature Cost Effect
Ante Bet 1.5x stake Boost to 2, 3, 4, or 5 modifiers in bonus (from 3, 4, 5, or 6 scatters)
Super Spin 1 20x stake One random-sized base game frame (no bonus trigger)
Super Spin 2 100x stake Two random-sized base game frames (no bonus trigger)
FS Bonus Round 100x stake Trigger 6 free spins directly (organic rate: 1 in 169.63 spins)

Ante is a sharp tool when the base game grind feels long – 1.5x cost for a cleaner bonus entry. Not available in the UK.

RTP / Hit Rate / Volatility

this slot offers three RTP settings: 96.52% (default), 95.55%, or 94.51%. Hit frequency sits at 1 in 6.63 spins across base game. The bonus round itself hits once every 169.63 spins on average. Medium volatility (3 out of 5 in-game scale). Max win is 10,000x your stake – a rare Maxi jackpot symbol or stacked frames with heavy overlap multipliers.

Theme / Presentation

Sunlit coral reef with big-eyed sea creatures – fish, seahorses, shrimp, shells, starfish – all rendered in a bright, Saturday-morning-cartoon style. A smiling octopus perches atop an Easter Island stone head at the reel top. Bubbles rise, reels stop with a bubble pop. Lighthearted, playful, cozy. No wilds means the frame collect system carries all the visual and mechanical weight – and it does the job.

Base Game Friction

Hit rate is low, so dead spins come often. Regular line wins rarely excite – they’re filler between frame hits. The frame collect mechanic is original and more engaging than typical symbol collection, especially when overlap multipliers fire. But the base game can feel flat if frames don’t land. Money symbol values (excluding jackpots) are moderate, and the Maxi jackpot range (400x-10,000x) can mislead players who skip the info section – they assume every Maxi is the 10,000x max, which it isn’t.

Pros

  • Frames up to 6x6 collect all money symbols inside
  • Overlapping frames apply x2 to x10 multipliers to overlap zone
  • 6 free spins with 1-4 modifiers; 2 frames guaranteed per spin
  • Frame size upgrades (every 3rd scatter) add +2 spins each
  • Money symbols worth up to 10,000x stake (Maxi jackpot)
  • Bonus round hits often enough to keep sessions moving

Cons

  • Base game hit rate 1 in 6.63 - expect long dry stretches
  • Regular line wins are weak; action lives in frame collects
  • Money symbol values moderate outside jackpot symbols
  • Maxi jackpot range (400x-10,000x) can confuse players
  • Bonus buy menu not available in UK
  • Frame system requires demo play to understand; not instantly intuitive

FAQ

What's the RTP of Bubble Up!?

Default RTP is 96.52%. Alternative tiers are 95.55% and 94.51%, depending on operator settings. Check your casino's game info to confirm which tier is active.

How often does the bonus trigger?

Organic bonus hit rate is 1 in 169.63 spins. You can buy direct entry for 100x your stake via the FS Bonus Round option, or use Ante Bet (1.5x stake) to boost your modifier count when you do hit naturally.

What happens when two frames overlap?

Money symbols in the overlap zone are boosted by a random multiplier of x2 to x10 before collection. This is the primary way to rack up larger payouts in base game - regular line wins alone won't carry a session.

How many free spins do I get, and what determines modifiers?

You always get 6 free spins regardless of scatter count. Landing 3, 4, 5, or 6 scatters awards 1, 2, 3, or 4 modifiers respectively. A pre-bonus pick game lets you match coin pairs to reveal them.

Can the frame grow during free spins?

Yes. Collect 3 scatters during the bonus and the minimum frame size upgrades (2x2 → 3x3 → 4x4 → 5x5 → 6x6). Each upgrade also grants +2 extra free spins, applied on the next spin.

Reviewed by Marek Dvořák – Senior Slot & Game Mechanics Analyst

this slot leans hard on the frame collect mechanic - it's original and more tactile than standard symbol collection, especially when overlaps trigger multipliers. The bonus round shines with dual frames and scatter upgrades. But the base game hit rate (1 in 6.63) is punishing, and regular line wins barely register. Medium volatility, 96.52% RTP, and a 10,000x ceiling keep it solid, though the frame system demands demo time before real money.
