About Bubble Up!

Bubble Up! is an online slot developed by Pragmatic Play, featuring six reels and 40 paylines. The game’s mechanics, payouts, and special features are structured around a marine theme, offering a variety of symbol types and bonus elements. All spins adhere to the main rules and payout structures provided by the developer.

How to Play

  1. Set your desired bet amount between £0.20 and £4.00.
  2. Spin the six reels. Winning combinations pay from left to right on adjacent reels, beginning from the far left.
  3. Only the highest win is awarded per payline, but wins on different paylines are combined for a total win.
  4. All win amounts are paid in coins and multiplied by the bet per line.
  5. If a malfunction occurs, all pays and plays during that round are void.

Scatter Symbol

  • The FS (Free Spins) scatter symbol can appear on any reel and is required to activate the Free Spins feature.

Money Symbols

Money symbols award payouts based on the number appearing and the current stake:

  • 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 spin, Money symbols are randomly assigned a value. These values 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 your base bet. The value is awarded if the symbol appears inside a frame.

The Frame Feature

  • During regular play, a frame can appear on the reels in a size of 2×2, 3×3, 4×4, 5×5, or 6×6.
  • A second frame may also land randomly in the same spin. Where two frames overlap and Money symbols are present in the shared area, those Money symbols are given a multiplier of 2x, 3x, 5x, 8x, or 10x.
  • All Money symbols appearing within any frame have their values combined and awarded together.

Free Spins Feature

  • Landing 3, 4, 5, or 6 Scatter symbols awards 6 free spins and activates 1, 2, 3, or 4 modifiers, respectively.
  • At the start of Free Spins, eight coin items appear. Revealing two identical coins grants that modifier for the entire round. Modifiers available are:
    • Additional Money symbols
    • More Scatter symbols
    • LEVEL UP: The starting frame is expanded to 3×3 in size
    • DUAL: Guarantees two frames every spin
  • At least one frame is guaranteed to appear with every free spin.
  • Scatter symbols during Free Spins are collected above the reels. For every set of three collected, the frame increases in size, and an extra two free spins are awarded, up to a maximum frame size of 6×6.
  • Special reels are active during this feature.
  • The maximum win is capped at 10,000x your bet. If this amount is reached in Free Spins, the bonus round concludes immediately and unused spins are forfeited.

Special Bet Options

  • The game offers two modes:
    • ANTE BET: Increases the bet multiplier to 30x, awarding more Free Spins modifiers (2, 3, 4, or 4 when triggering with 3, 4, 5, or 6 Scatter symbols).
