Bubble Craze Free Spins

The maximum duration of free spins is five turns. A series is activated when three Scatter symbols appear on the game screen. The feature of bonus spins is that a transforming symbol or a multiplier symbol appear on the screen as a result of every spin. Every free spin produces a guaranteed win.

During free spins, the total bet is not removed for activating the reels. All wins are credited to your balance. The series of free spins cannot be extended or restarted during the bonus rounds. 

Colours of balls and rewards

Combinations in the Bubble Craze slot are formed of at least four balls of the same colour, neighbouring each other. As a result of a spin, one or more winning combinations may land. The maximum number of single-type bubbles in a combination is nineteen.

Each winning combination has its own reward displayed in coins. Wins grow depending on the number of bubbles in a winning combination. For example, the highest-paying silver bubble earns you 75, 100, 150, 200, 250, 300, 400, 500, 600, 750, 1,000, 1,500, 2,000, 2,500, 5,000 and 10,000 coins for 4-19 symbols in a row, respectively. Other pictures award you the following way:

  • Brown and violet pictures – from 10 to 1,000 coins for 4–19 identical balls, respectively
  • Blue and green – from 15 to 1,500
  • Yellow and orange – from 25 to 2,000
  • Red – from 50 to 5,000

You can raise your rewards or activate additional game options by collecting bonus balls in the game window. Bonus symbols and their functions The Bubble Craze game comes with three types of bonus balls:

  • A symbol of transformation
  • Multiplier symbols
  • A symbol to activate free spins

The symbol of transformation has 8 arrows pointing in all directions, which appears in a bubble of any colour. At the end of a spin, the symbol paints the neighbouring balls in the colour that is assigned to this bonus picture. As a result of a spin, several symbols of transformation can appear in the game window simultaneously.

The multiplier symbols are represented by pictures of two types: х2 and х5. Each of them raises the reward for a combination the corresponding number of times. Multipliers also appear in balls of any colour. If such a bubble takes part in a combination, your win enlarges. If two multipliers have played in combinations simultaneously, only the largest of them is counted.

The Scatter is a symbol in the form of a rainbow coloured flower. It does not matter in which ball the picture has appeared and where exactly it is positioned in the game window. The main goal is to collect three of these pictures at a time to launch a series of free spins.

Bubble Craze is an unconventional slot by IGT based on the popular Bubbles game. Experienced players notice a number of both advantages and disadvantages of the slot machine. The weak points of the slot include:

  • Small payouts for combinations
  • A "floating" theoretical return to player (92.65 – 96.2%)
  • The lack of a risk game

Among the advantages are:

  • A high probability of forming combinations due to the non-standard rules and the absence of paylines
  • Increased chances to win with the help of the transformation symbol
  • The opportunity to earn a bigger reward for a winning combination with the help of multiplier symbols
  • Guaranteed rewards in the course of free spins

The absence of the auto spin option is related to the functional disadvantages of the demo version. The feature is only available in the real game. Play for fun more neon slot games online available in their free demos at neonslots.com.
