Bonus Features Deep Dive
1. The Invasion Meter
- Mechanism: A meter on the side of the screen fills up as Invader symbols (the premium symbols) form part of winning combinations.
- Level 1 - UFO Attack: When the first stage is full, 1-2 UFO Wilds (with 2x or 3x multipliers) are added to the reels on the next spin.
- Level 2 - Mothership Bonus: Filling the meter completely triggers this base game feature. The screen shifts to a bonus round where you shoot at a giant Mothership to reveal instant cash prizes, multiplier wilds, or a trigger for the Free Spins round.
2. Free Spins Bonus Round
- Trigger: Land 3 or more Scatter (Warp Gate) symbols OR unlock it via the Mothership Bonus.
Award - 3 Scatters: 8 Free Spins
- 4 Scatters: 10 Free Spins
- 5 Scatters: 12 Free Spins
Enhanced Gameplay - The Invasion Meter is active and fills faster.
- Each time the meter is filled during free spins, a random reel is chosen and locked with a 2x multiplier for the remaining duration.
- Multiple reels can become locked with multipliers, which compound for astronomical win potential.
3. Pixel Perfect Respin
- Trigger: Can occur randomly on any non-winning spin.
- Effect: The reels are shaken up, and a cluster of 4-6 low-value symbols is transformed into the same high-paying Invader symbol, often creating a winning combination.
