Modifier Feature

Blobsters Clusterbuster has 3 locked modifiers when the game starts. However, there’s a way to unlock them. Usually, if a winning cluster hits next to the 3×3 UFO area in the middle, the adjacent lights go green. A feature unlocks and activates on the next spin if all the lights go green.

All the lights go back to being turned off once the feature starts. If you unlock all 3 features, they can randomly land on future spins. 

In addition, more than 1 feature can activate on a single spin if you have already unlocked it. The character sitting next to the UFO (called Blobby) can also randomly switch on the last light for you if you’ve already lit up the 1st and 2nd lights.

The modifiers are as follows:

  • Upgrader: Blobby shoots random low-value symbols not part of any clusters and upgrades them into random high-value symbols. Blobby can upgrade 8 to 24 symbol upgrades in a standard game or 11 to 31 in the Invader Spins bonus.
  • Frenzy: Blobby shoots at 5 to 20 random symbols, which then turn into wilds. These new wilds can substitute for regular symbols and could help to complete winning combinations.
  • Supersize: Blobby shoots anywhere from 2 to 4 random high-value or wild symbols, growing them to 3×3-sized Super Symbols. These count as 9 regular-sized symbols.

Invader Spins Feature

If you unlock all 3 modifiers, you can win 10 Invader Spins each time all the lights on the UFO go on. During Invader Spins, modifiers can land at an increased rate. Plus, Blobby’s UFO can activate up to 3 times during the spins if all the lights are on.Every time you activate the UFO, you win 3 more spins and increase the global wins multiplier. The 1st, 2nd, and 3rd feature triggers can increase the multiplier value to x3, x7, and x12, respectively.

Return To Player

Return to Player (RTP): 95.7%.

RTP is used to explain the potential money that an online slot or casino game can pay back to players. It appears as a percentage and is generally calculated from gameplay over a long duration of time.

For example, if a slot has a RTP of 97% this means that it could pay back £97 for every £100 wagered.

However, there is no guarantee that players will receive this amount, as slot payouts are entirely random.
