Win & Spin Symbols

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.
