What Is Bubble Up!?

Bubble Up! is a 6-reel online slot provided by Pragmatic Play. The game offers 40 paylines and incorporates a variety of features and unique gameplay mechanics designed to create an engaging experience. Players can place bets ranging from £0.20 to £4.00 per spin, with a high volatility profile.

How Does the Main Game Work?

  • Winning combinations pay from left to right on adjacent reels, starting from the leftmost reel.
  • Payouts occur according to the selected paylines, with only the highest win per line paid.
  • If wins occur on multiple paylines, their values are combined into the total win for that spin.
  • Wins achieved during Free Spins are added to standard payline wins.
  • All win amounts are calculated in coins and multiplied by the bet per line.
  • The Free Spins total win, as recorded in history, reflects the overall amount won during the feature.
  • A malfunction during gameplay voids all pays and results.

What Are the Regular Symbol Payouts?

Payouts are determined by the current bet level. The following table shows possible rewards for matching symbols in succession from left to right:

How Do Scatter and Money Symbols Work?

Scatter Symbol

  • The Scatter symbol (FS) can appear on any reel. Its primary function is to trigger the Free Spins feature when enough are present in a single spin.

Money Symbols

This symbol awards prizes based on the number that land in a single spin. Prizes vary with the bet level, and the payouts are:

  • 6 Money Symbols – £20.00
  • 5 Money Symbols – £10.00
  • 4 Money Symbols – £5.00
  • 3 Money Symbols – £2.00
  • 2 Money Symbols – £1.00

Each Money Symbol that lands can take a random value. These values might include: 0.5x, 1x, 1.5x, 2x, 2.5x, 3x, 4x, 5x, 7.5x, 8x, 10x, 15x, 20x (MINI), 40x (MINOR), 80x (MAJOR), 200x (GRAND), 400x, 800x, 2000x, or 10,000x (MAXI) times the base bet. These values are available to be won if they land inside a frame, as described below.

What Is the Frame Feature?

  • In the base game, a frame can appear randomly with a size of 2×2, 3×3, 4×4, 5×5, or 6×6 symbols.
  • A second frame can also appear, and when both overlap, any Money Symbol located in the overlapped area receives a random multiplier of either 2x, 3x, 5x, 8x, or 10x.
  • All Money Symbols within any frame have their values totalled and awarded together.

How Does the Free Spins Feature Work?

  • Landing 3, 4, 5, or 6 Scatter symbols activates 6 Free Spins. Depending on the number of Scatters, players receive 1, 2, 3, or 4 modifiers, respectively.
  • At the beginning of the Free Spins bonus, eight coin items appear. Uncovering two matching coins grants that corresponding modifier for the duration of the Free Spins round.
  • Modifiers that may be awarded include:
    • Increased number of Money Symbols
    • Increased number of Scatter symbols
    • LEVEL UP: Frame starts expanded to 3×3
    • DUAL: Two frames appear on every spin
  • Each Free Spin is guaranteed to feature at least one frame.
  • During Free Spins, any Scatter symbols that land are collected above the reels. Every time three are collected, the frame size increases and two additional Free Spins are granted, up to a maximum frame of 6×6.
  • Special reels are used throughout the Free Spins feature.
  • The maximum possible win on any play is capped at 10,000 times the bet. If this amount is reached during Free Spins, the round concludes and any remaining spins are forfeited.

What Are the Special Bets?

  • The slot allows players to select a bet multiplier:
    • ANTE BET (30x): Increases the number of Free Spins modifiers available (receiving 2, 3, 4, or 4 modifiers when 3, 4, 5, or 6 Scatters trigger Free Spins).
    • Normal Play (20x): Standard game play setup.

How Do the Paylines Work?

  • There are 40 paylines in total, all paying from left to right beginning on the first reel.

What Is the Volatility and RTP?

  • Bubble Up! is categorised as high volatility, meaning outcomes may vary widely in value and frequency.
  • The Return to Player (RTP) information is displayed within the slot game.

What Are the Minimum and Maximum Bets?

  • The minimum bet per spin is £0.20.
  • The maximum bet per spin is £4.00.
