Type of play
- Must-hit/positive-state “when to play” based on expanded reel height persistence (3-spin timer) and the max-height “Add Wild” event.
How the advantage works (what you’re exploiting)
- Volcano (Flame) / Trident (Ocean) symbols expand that reel’s height for the next 3 spins (reels start 3-high, can grow to 6-high).
- Taller reels = more paylines/ways coverage, more chances to trigger Free Games, and more chances to land 6 scatters to start Hold & Spin.
- If a volcano/trident lands on a reel that is already max height (6-high), it triggers Add Wild: random wilds are added (typically on reels 2–5), which can create very large line hits. It also resets that reel’s “spins remaining” back to 3.
