Bonus features

Mega symbols

  • Mega symbols may appear in 2x2, 3x3, 4x4, 5x5, 6x6, 7x7 symbol sizes.
  • Each mega symbol has a cluster value randomized up to 13.
  • When forming wins, a mega symbol counts as a single symbol, but its cluster value is used when determining the payout of the winning cluster.
  • Each winning mega symbol leaves a WILD on the grid. If a mega symbol cannot drop down, it fills up the space with its own 1x1 versions, without cluster values. On any non-winning round, 5 to 10 QUANTUM WILDS may be added randomly.
  • GARGANTOON WILDS may appear through the QUANTUMETER only. WILDS substitute for all symbols! Each winning symbol counts as one charge towards the QUANTUMETER, but mega symbols add their cluster values.


  • QUANTUMETER has 4 charge levels and holds up to 100 charges.
  • Collect 25 charges for DISINTEGRATION, 50 for METAMORPHOSIS, 75 for RADIATION, and 100 for GARGANTOONZ
  • When there are no more cascades, the next charge feature in line triggers. QUANTUMETER inactivates for the round if all features are played out.
  • DISINTEGRATION removes all instances of 4 randomly selected symbols. METAMORPHOSIS randomly transforms all instances of one symbol into a different symbol, including mega symbols. RADIATION adds 1-4 mega symbols and 2-5 QUANTUM WILDS randomly.
  • GARGANTOONZ plays out in 2 steps, one by one after wins conclude. Firstly, all mega symbols turn into mega GARGANTOONZ. At least 3 mega GARGANTOONZ appear, regardless of how many mega symbols are present. Additionally, 2-4 1x1 GARGANTOONZ appear. Mega GARGANTOONZ are not removed with wins. Secondly, the mega GARGANTOONZ break down into 1x1 GARGANTOONZ, which are removed normally
