How do the Fluctometer and Electric Wilds work?
- Fluctometer: each spin, one monster symbol is picked at random. Wins with it charge the Fluctometer, and when it is full (11 symbols) it adds 1 to 3 Electric Wilds.
- Uncharged Wilds: they land as blockers. A winning cluster next to one turns it into an Electric Wild.
- Wild Pair Explosion: when 2 or more Electric Wilds are left after the cascades, they explode.
How does the Quantumeter work?
Electric Wilds charge the Quantumeter. The first level is reached at 55 charges, and the lower levels release Energoon Wilds. A full meter releases Gargantoon, a 3×3 wild. If you overcharge it to 135, Gargantoon gets a 2x multiplier.
