Bonus Features Deep Dive
1. The Tumble Feature (With a Gravitational Twist)
- Mechanics: Standard cascading reels, where winning symbols explode and new ones fall from the top.
- The Twist - Gravitational Drift: After a tumble, symbols don't just fall straight down. They can "drift" horizontally to fill empty spaces, often spontaneously creating new, adjacent clusters for consecutive wins from a single initial trigger.
2. Anti-Gravity Spins (Free Spins)
- Trigger: Land 4, 5, or 6 Anti-Gravity Crystal Scatters.
- 4 Scatters: 10 Anti-Gravity Spins
- 5 Scatters: 15 Anti-Gravity Spins
- 6 Scatters: 20 Anti-Gravity Spins
Special Rules - Infinite Tumble Multiplier: A win multiplier starts at x1. With every subsequent cascade, the multiplier increases by +1. Crucially, this multiplier does not reset between spins and continues to grow throughout the entire bonus round.
- Increased Black Hole Frequency: The Black Hole Wild appears more often, using its gravitational pull to create massive, winning clusters that drive the multiplier ever higher.
3. The Cosmic Anomaly (Random Base Game Feature)
- Trigger: Can occur randomly on any non-winning tumble.
Mechanics: Space-time warps, causing one of two effects - Nebula Expansion: Expands the grid to 8x8 for one tumble, creating the potential for a gigantic cluster.
- Symbol Singularity: All lower-paying gem symbols on the grid transform into a single, matching high-paying gem.
