Win Lines

• All games are played with 25 win lines.
• Win line diagrams are provided in the rules (see related section for reference).
• Only the highest award is paid per winning combination.
• Wins pay left to right starting from the leftmost reel.

Wild Symbol

• The Wild symbol substitutes for all symbols except Win & Spin symbols.
• The Wild appears on reels 2, 3, 4, and 5 in the standard spins base game only.

Win & Spin Symbols

• Win & Spin symbols feature in both the base game and the Win & Spin Bonus.
• There are two types:
  • Invader cash symbols: Display a cash value.
  • Possible values: 1x to 9x the active stake.
  • UFO Jackpot symbols: Display Mini, Minor, or Major jackpots.
  • Mini Jackpot: 10x base bet
  • Minor Jackpot: 25x base bet
  • Major Jackpot: 100x base bet
• Landing 6 or more of any Win & Spin symbol triggers the Win & Spin Bonus.
• Values are awarded only in the Win & Spin Bonus.

UFO Coin Trigger

• Every UFO Win & Spin symbol landing during the base game adds a coin to the coin pile above the reels.
• The coin pile can increase up to 5 levels, but size does not affect the trigger chance.
• After adding coins, the pile may tumble, triggering the Win & Spin Bonus. Multiple coins increase this chance.
• If fewer than 6 Win & Spin symbols land, extra symbols are added before the bonus starts.
• Bonus triggers from the coin pile increase the chance of landing UFO symbols during the bonus.

Win & Spin Bonus

• Awarded when 6 or more Win & Spin symbols land in any position.
• Bonus can also be triggered by the coin pile mechanism.
• Initially, 3 spins are awarded. Each new Win & Spin symbol resets the spins to 3.
• Bonus continues until all spins are used or all 15 positions are filled.
• At the end, all Win & Spin values in view are awarded.
• Filling all 15 positions awards the Grand Jackpot (1000x base bet) in addition to other prizes.

Cannon Feature

• If no new Win & Spin symbols are added on the final spin, the cannon may appear.
• Mini invaders are added to empty positions. The cannon may convert one or more into Win & Spin symbols.
• Remaining mini invaders disappear if less than 15 positions are filled, resetting spins to 3 if needed.

• Only Win & Spin symbols appear; all others are removed.
